Legionnaires disease

is a common name for one of the

several illnesses caused by

Legionnaires' disease bacteria (LDB).

resulting from entry of endogenous or

extrogenous substances into the lower

airway.

Anaerobic Bacteria (S. Pneumoniae, H.

influenzae, S. aureus)


8/174

SIGNS AND SYMPTOMS (Legionnaires Disease)

Legionnaires' disease usually develops two

to 14 days after exposure to the legionella

bacteria. It frequently begins with the

following signs and symptoms

Headache

Muscle pain

Chills Fever that may be 104 F (40 C) or higher


9/174

If you have Legionnaires' disease, by thesecond or third day, you'll develop other signsand symptoms that may include:

Cough, which may bring up mucus and sometimes blood

Shortness of breath Chest pain

Fatigue

Loss of appetite

Gastrointestinal symptoms, such as nausea, vomiting anddiarrhea

Confusion or other mental changes


10/174

Complications:

Respiratory failure

Septic shock

Acute kidney failure


11/174

Anatomy and Physiology

Function:

The function of the respiratory system is to give us asurface area for exchanging gases between the air

and our circulating blood. It moves that air to andfrom the surfaces of the lungs while it protects thelungs from dehydration, temperature changes andunwelcome pathogens. It also plays a part in makingsounds such as talking, singing, other nonverbalsounds and works with the central nervous systemfor the ability to smell.


12/174

Upper Respiratory Anatomy

The upper respiratory system

consists of the nostrils (externalnares), nasal cavity, nasalvestibule, nasal septum, bothhard and soft palate,nasopharynx, pharynx, larynx andtrachea. Within the nostrils,course hairs protect us from dust,

insects and sand. The hard palateserves to separate the oral andnasal cavities. There is aprotective mucous membranethat lines the naval cavities andother parts of the respiratorytract. It is secreted over the

exposed surfaces and then thecilia sweeps that mucus and anymicroorganisms or debris to thepharynx, so it is swallowed andthen destroyed in stomach acids.


13/174

Lower Respiratory Anatomy

The trachea branches off into what is known as thebronchi (more commonly called bronchial tubes).These two main bronchi have branches forming thebronchial tree. Where it enters the lung, there isthen secondary bronchi. In each lung, the secondary

bronchi divides into tertiary bronchi and in turnthese divide repeatedly into smaller bronchioles. Thebronchioles control the ratio of resistance to airflowand distribution of air in our lungs. The bronchiolesopen into the alveolar ducts. Alveolar sacs are at the

end of the ducts. These sacs are chambers that areconnected to several individual alveoli, which makesup the exchange surface of the lungs.


14/174

The Lungs

The human respiratory system has two lungs, whichcontain lobes separated by deep fissures.

Surprisingly, the right lung has three lobes while the

left one has only two lobes. The lungs are made up

of elastic fibers that gives it the ability to handlelarge changes in air volume. The pleural cavity is

where the lungs are located. The diaphragm is the

muscle that makes up the floor of the thoracic cavity

and plays a major role in the pressure and volume ofair moving in and out of the lungs.


15/174

Significance

Our lungs filter and deliver oxygen that is

necessary for healthy red blood cells. It isimportant that we keep the respiratory tract

healthy through proper rest, hydration, diet

and exercise


16/174

Pathophysiology

Risk factors include:

Alcoholism

Cigarette smoking

Diseases such as kidney failure or diabetes

Diseases that weaken the immune system, including cancer

Long-term (chronic) lung disease, such as chronic obstructivepulmonary disease (COPD)

Long-term use of a breathing machine (ventilator)

Medicines that suppress the immune system, includingchemotherapy and steroid medications

Older age

23/174

Diagnostic/Laboratory Results

1. Arterial blood gases

Blood gases is a measurement of how muchoxygen and carbon dioxide is in your blood.

It also determines the acidity (pH) of yourblood

2. Chest x-ray-Definition

A chest x-ray is an x-ray of the chest, lungs,heart, large arteries, ribs, and diaphragm


24/174

3.Complete blood count (CBC), including white blood

cell count

a basic evaluation of the cells (red blood cells,

white blood cells, and platelets) suspended in the

liquid part of the blood (plasma). It involves

determining the numbers, concentrations, and

conditions of the different types of blood cells

4. Erythrocyte sedimentation rate

ESR stands for erythrocyte sedimentation rate. It is

a test that indirectly measures how muchinflammation is in the body.


25/174

5. Liver function tests

Liver function tests, or LFTs, include tests for

bilirubin, a breakdown product of hemoglobin,and ammonia, a protein byproduct that isnormally converted into urea by the liverbefore being excreted by the kidneys.

6. Sputum indirect fluorescent antibody test

Sputum direct fluorescent antibody (DFA) is atest that looks for microorganisms in lung

secretions


26/174

Pharmacological management:

Antibiotics commonly used to treat this

condition include:

Quinolones (ciprofloxacin, levofloxacin,moxifloxacin, or gatifloxacin)

Macrolides (azithromycin, clarithromycin, or

erythromycin)


27/174

Other treatments may include:

Fluid and electrolyte replacement

Oxygen (given through a mask or breathingmachine)


28/174

NURSINGMANAGEMENT

Improving airway patency

Encourage hydration (2 to 3 L/day)

Chest physiotherapy (percussion and postural drainage) isimportant in loosening and mobilizing secretions

Oxygen therapy


29/174

Promoting rest and conserving energy

Encourage the patient to rest and avoid

overexertion and possible exacerbation of

symptoms.

Semi-fowlers position

Change position frequently to enhance secretion

clearance and pulmonary ventilation andperfusion.

PNEUMOCONIOSIS

REPORT-NCM 103 LECTURE


33/174

DEFINITION

Any disease of the lung

caused by chronic inhalation of

dust, usually mineral dust of

occupational or environmental

origin.


34/174

DEFINITION

Some kinds of

pneumoconioses are

asbestosis, coal workers

pneumoconiosis and silicosis.


35/174

The development of pneumoconiosis

is dependent on the following:

The amount of dust retained in the lung and

airways.

The size and shape of the particles (particlesbetween 1 and 5 m are the most dangerous).

Solubility and physiochemical properties of

the particles.

Concomitant effects of other irritants, such as

smoking.


36/174

Examples of Pneumoconiosis

Asbestos exposure from mining,

insulation related work: asbestosis.

Coal dust exposure from coal mining:coal workers pneumoconiosis.

Silica exposure from foundry work,

sandblasting, stone cutting: silicosis


37/174

ASBESTOSIS

Chest X-ray in asbestosis shows

plaques above diaphragm


38/174

ASBESTOSIS

-a breathing disorder caused by inhaling

asbestos fibers.

-prolonged accumulation of these fibers inyour lungs can cause scarring of lung tissue

and shortness of breath.

-symptoms can range from mild to severe,

and usually don't appear until years after

exposure.


39/174

ASBESTOSIS

Signs and Symptoms:

Shortness of breath

Decreased tolerance for physical activity Coughing

Chest pain

Finger deformity (clubbing) in some cases


40/174

COAL WORKERS PNEUMOCONIOSIS

This chest x-ray shows coal worker's

lungs. There are diffuse, small, light

areas on both sides (1 to 3 mm) in all

parts of the lungs


41/174


-also called as black lung disease.

-caused by long exposure to coal dust.

-common affliction of coal miners and otherswho work with coal.

-inhaled coal dust progressively builds up inthe lungs and is unable to be removed by the

body that leads to inflammation, fibrosis, andin the worst case, necrosis.


42/174


Signs and Symptoms:

Chronic cough

Shortness of breath


43/174

SILICOSIS


44/174

SILICOSIS

-also known as Potter's rot, is a form of

occupational lung disease caused by

inhalation ofcrystalline silica dust, andis marked by inflammation and scarring

in forms ofnodular lesions in the upper

lobes of the lungs.


45/174

SILICOSIS

Signs and Symptoms:

Shortness of breath following physicalexertion

Cough

Minor fatigue

Loss of appetite

Occasional chest pains

Bluish skinat edges of extremities


46/174

SILICOSISThree types of silicosis:

Simple chronic silicosis-results from long-termexposure (more than 20 years) to low amounts of silicadust. Swellings caused by the silica dust form in thelungs and chest lymph nodes. This disease may causepeople to have trouble breathing.

Accelerated silicosis-occurs after exposure to largeramounts of silica over a shorter period of time (5 - 15years). Swelling in the lungs and symptoms occurfaster than in simple silicosis.

Acute silicosis-results from short-term exposure tovery large amounts of silica. The lungs become veryinflamed and can fill with fluid, causing severeshortness of breath and low blood oxygen levels.

66/174

MEDICAL/SURGICALMANAGEMENT Asbestosisa.Bronchoalveolar lavage

-helpful in diagnosing infections that may present

with diffuse infiltrates, which simulate asbestosis.

-can provide quantitative information by asbestos

fiber counts. More than 1 asbestos body (ie,

coated asbestos fiber) per milliliter of lavage

effluent suggests significant exposure.


67/174

MEDICAL/SURGICALMANAGEMENT

b.Bronchoscopy

-performed to facilitate BAL.

-indicated for airway examination when radiologic

studies are suggestive of bronchogenic carcinoma.

-Transbronchoscopic lung biopsy is not

recommended for diagnosis of asbestosis. This

procedure yields inadequate tissue and may cause

crush alterations to the tissue.


68/174


Open-lung biopsy is not indicated in most cases. However,this procedure provides sufficient tissue for the pathologistto make a definitive diagnosis.

Antibiotics may be prescribed to combat infection. Aspirinor acetominophen (Tylenol) can relieve minor discomfortand bronchodilators that are swallowed or inhaled can relaxand widen breathing passages.

Diuretics (drugs that increase urine production andexcretion) or digitalis glycoside (Digitalis purpurea) areprescribed for some patients. Others may need to usesupplemental oxygen or use less salt.


69/174

a.Bronchodilator medications

b.Inhaled corticosteroids

c. Chest physiotherapyd. Oral corticosteroids.

e. Home oxygen therapy

f. Antibiotics for bronchitis

g. Influenza vaccine

h. Pneumonia vaccine


70/174


Silicosis

a. Antibiotics for bacterial lung infection.

b. TB prophylaxis for those with positive tuberculin skin test.

c. Prolonged anti-tuberculosis (multi-drug regimen) forthose with active TB.

d. Chest physiotherapy to help the bronchial drainage of

mucus.

e. Oxygen administration to treat hypoxemia, if present.


71/174


Bronchodilators to facilitate breathing.

Lung transplantation to replace the damaged lung

tissue is the most effective treatment, but is

associated with severe risks of its own.

For acute silicosis, Whole-lung lavage (see

Bronchoalveolar lavage) may alleviate symptoms,

but does not decrease overall mortality.


72/174

NURSINGMANAGEMENT

Monitor vital signs.

Check for the presence of cyanosis (blue color) of

the feet or hands.

Check for the presence of edema (swelling) of thefeet and lower legs.

Supportive treatment of symptoms includes

respiratory physiotherapy to remove secretions

from the lungs by postural drainage, chestpercussion, and vibration.


73/174

NURSINGMANAGEMENT

Position in high fowlers of semi fowlers.

Provide health teachings such as:

a. Stop smoking if you are a heavy smoker, it is

vital that you stop this habit as soon as you havebeen diagnosed with pneumoconiosis.

b. Prevent infections by avoiding crowds and

persons with colds or similar infections.

c. Avoid exposure to dust.

75/174

Pleurisy


76/174

Overview of the Disease

Also known as pleuritis, is an inflammation of the pleura thatproduces sharp chest pain with each breath.

The membranous pleura that encases each lung is composedof two close-fitting layers; between them is a lubricating fluid.

If the fluid content remains unchanged by the disease, the pleurisy issaid to be dry.

If the fluid increases abnormally, it is a wet pleurisy, or pleurisy witheffusion.

If the excess fluid of wet pleurisy becomes infected, withformation of pus, the condition is known as purulent pleurisy


77/174

Two types of pleurisy

Dry pleurisy-the more common condition, the

inflamed pleurae rub directly against each

other.

Wet pleurisy- fluid oozes from the inflamed

tissue into the space between the lungs and

the chest wall. This fluid may compress the

lungs, making breathing difficult.


78/174

Both types of pleurisy often occur as complications

of respiratory tract infections, such as pneumonia,

viral infections, and tuberculosis, and are more likelyto develop in persons who are highly susceptible to

such infections. They also can be caused by a tumor

or an injury.

Some cases are due to certain gastrointestinal tract

diseases, particularly of the liver and pancreas, which

can inflame the diaphragm (the large muscleseparating the chest and abdominal cavities) and the

portions of the pleurae that cover the diaphragm.


79/174

Causes

Infections (pneumonia or tuberculosis.)

It is often a sign of a viral infection of the

lungs.

Anatomy and Physiology

The Pleura

A thin, moist, and slippery membrane that covers the outer surface of theof the rib cage. Parietal Pleura- is the outer layer of the pleura that lines the walls of the

thoracic cavity, covers the diaphragm, and forms the sac containing each lung. Parietal means relating to the walls of the cavity

Visceral Pleura- is the inner layer of pleura that surrounds each lung. Visceral means relating to the internal organs.

Pleural Cavity- also known as pleural space is the airtight area betweenthe layers of the pleural membranes. This space contains a thin layer offluid that allows the membranes to slide easily during breathing

Assessment

Nursing History The history of patient with pleurisy is very important. It may

suggest pleural empyema.

A known diagnosis of SLE/ history of takingdrugs(precainamide, hydralazine, quinidine), associated with

lupus syndrome, sarcoidosis, rheumatoid disease/uremia should alert the clinician to the potential cause ofpleurisy.

An increase leucocytes count with a shift to left suggestbacteria infection, i.e. pneumonia, esophageal rupture(mediastinitis, empyema), hepatic/ splenic abscess/ severe

inflammation (pancreatitis). Leucopoenia maybe seen in patient with viral pleurisy or SLE.


85/174

Signs and Symptoms:

fever

Shortness of breath

Weight loss Poor appetite

Sharp chest pain with breathing.

Inability to take a deep breath due to chestpain


86/174

Physical Exam

Using a stethoscope, the doctor will listen to the patientsbreathing to find out whether your lungs are making anyabnormal sounds.

In pleurisy, the inflamed layers of the pleura make a Rough, scratchy (pleural friction rub).

If you have a pleural effusion, fluid buildup in the pleuralspace will prevent a friction rub. But if the theres a lot offluid, the doctor may hear a dull sound when he or she tapson your chest, or he or she may have trouble hearing anybreathing sounds.

Muffled or dull breathing sounds also can be a sign of apneumothorax.

Diagnostic Studies


87/174

Diagnostic Studies

Chest X Ray

A chest x ray is a painless test that creates apicture of the structures in your chest, such asyour heart, lungs, and blood vessels. This testmay show air or fluid in the pleural space.

A chest x ray also may show what's causing apleural disorderfor example, pneumonia, afractured rib, or a lung tumor.

Sometimes a chest x ray is taken while you lie

on your side. This may show fluid that didn'tappear on an x ray taken while you werestanding


88/174

Blood Tests

Blood tests can show whether you have anillness that may make it more likely that you'lldevelop pleurisy or another pleural disorder.

Such illnesses include bacterial or viralinfections, pneumonia, pancreatitis (an

inflamed pancreas), kidney disease, or lupus. Blood may show organ failure:

High BUN/Creatinine -- Kidney failure

High liver or pancreatic enzymes

l l d


89/174

Arterial Blood Gas Tests

For this test, a small amount of blood is taken

from an artery, usually in your wrist. It's then

checked for oxygen and carbon dioxide levels.

This test shows how well your lungs are taking

in oxygen.


90/174

Thoracentesis

Once your doctor knows whether fluid has built up in thepleural space and where it is, he or she can remove a samplefor testing.

This is done using a procedure called thoracentesis (THOR-a-

sen-TE-sis). During the procedure, your doctor inserts a thinneedle or plastic tube into the pleural space and draws outthe excess fluid. After the fluid is removed from your chest,it's sent for testing.

The risks of thoracentesis usually are minor and will get betteron their own, or they're easily treated. Your doctor may do achest x ray after the procedure to check for complications.


91/174


92/174

Fluid Analysis

Doctors look at the fluid removed during

thoracentesis under a microscope. They look

at the chemicals in it and its color, texture, and

clearness for signs of infection, cancer, orother conditions that may be causing fluid or

blood to build up in the pleural space.


93/174

Biopsy

If your doctor thinks that tuberculosis or cancer may havecaused fluid to build up in your pleural space, he or she maywant to look at a small piece of the pleura under amicroscope.

To take a tissue sample, your doctor may do one of the

following procedures: Insert a needle through the skin on your chest to remove a

small sample of the outer layer of the pleura.


94/174

Insert a small tube with a light on the end(endoscope) into tiny cuts in your chest wall so thathe or she can see the pleura. Your doctor can thensnip out small pieces of tissue. This procedure mustbe done in a hospital. You'll be given medicine totemporarily put you to sleep while the procedure isdone.

Snip out a sample of the pleura through a small cutin your chest wall. This is called an open pleuralbiopsy. It's usually done if the sample from theneedle biopsy is too small for an accurate diagnosis.This procedure must be done in a hospital. You'll be

given medicine to temporarily put you to sleep whilethe procedure is done.


95/174

Medical and Surgical Management

Treat underlying disorder

Rest

Oxygen, if levels are low

Aspirin and other NSAIDs (e.g., Ibuprofen, Indocin, etc.) are

effective in reducing the inflammation, fever, and pain. Painkillers such as codeine can help.

In severe pain, a nerve block is performed using a numbingagent (e.g., Xylocaine) that is injected into the nervesbetween the ribs for temporary relief of pain.

Therapeutic Thoracentesis is done to remove the effusion,which helps breathing.


96/174

NursingManagement

Because the patient is in pain on inspiration, thenurse offers suggestions to enhance comfort, such as Lying on the painful side may be more comfortable,

because it will splint the chest wall, reduce the stretchingof the pleurae

Breathing deeply and coughing to clear mucus as the paineases

Getting rest

Limiting movement on the side of affected pleura to lessenthe pain.

Also teaches the patient to use hands or pillows to splintthe rib cage while coughing.

Bronchogenic Carcinoma


98/174

Overview

Lung Cancer Cancer is caused by a variety of malignant

neoplasm in which cells mutate and

invade surrounding tissue and can travelvia lymphatic system or blood vessels to

other secondary sites.


99/174

Primary cancer is the body system or site

where the cancer was first observed

Secondary when it spreads (metastasizes)

from cancer in other areas of the body.

Etiology and Pathogenesis

Occupational associations: asbestos,uranium( in miners), arsenical fumes, nickel,radon gas.

Other factors include air pollutions , ionizingradiation .

Nowadays it is reported that tuberculosis isassociated with the incidence of lung cancer.

Eti l d P th i


109/174


Many factors influence the formation of lung

cancer. The development of lung cancer is

multistep process. The transformation of normal

bronchial epithelial

cells to malignant cells is unknown.


110/174

Perhaps It is related to:

damage to cellular DNA

alteration in cellular oncogene

expression; tumor-derived factors thatstimulate cellular division.

Eti l d P th i


111/174


Chronic inflammation of the lung, such as

from interstitial fibrosis and areas of

scarring is associated with the occurrence

of adenocarcinoma.

Genetic factors also involve the formation

of lung cancer.

TNM S t


113/174

TNMSystem

a classification system developed and recently

revised by the American Joint Committee on

Cancer (AJCC) and the Union Internationale

Contre le Cancer (UICC; International UnionAgainst Cancer). According to this system:

T = tumor size

N = node involvementM = metastasis status

T mors


114/174

Tumors

TX: Tumor cannot be evaluated or tumor isproven by the presence of cancer cells in thesputum or bronchial washings, but it cannotbe seen during imaging or bronchoscopy

("occult" tumor)

T0: No evidence of primary tumor

Tis: Carcinoma in situ


115/174

T1: Tumor 3 centimeters (< 3 cm) or less ingreatest dimension, surrounded by lung orpleura, and not located in the main stembronchus

T2: Tumor more than 3 centimeters (> 3 cm) ingreatest dimension, or tumor involving themain stem bronchus, 2 cm or more from thecarina, or tumor invading the visceral pleura,

or tumor with incomplete lung expansion orobstructive lung infection that does notinvolve the entire lung

T3: Tumor of any size that directly invades the chest


116/174

wall, diaphragm, pleura, or pericardium, or tumorthat involves the main stem bronchus less than 2

centimeters (< 2 cm) from the carina (ridge betweenthe right and left main stem bronchi), or tumor thatis associated with complete lung collapse orobstructive lung infection involving the entire lung.

T4: Tumor of any size that invades the heart, greatvessels (aorta, superior or inferior vena cava,

pulmonary artery, or pulmonary vein), trachea,esophagus, vertebral body, or carina, or separatetumor nodules in the same lung lobe, or tumorassociated with a malignant pleural effusion.

Nodes


117/174

Nodes

The regional lymph nodes (N) are clinically divided intothe following categories:

NX: Regional lymph nodes cannot be assessed

N0: Regional lymph nodes contain no metastases

N1: Metastasis to same-side peribronchial (aroundthe bronchi) and/or hilar (pit in the lungs where

vessels enter and exit) lymph nodes and nodeswithin the lungs that are involved by direct spreadof the primary tumor

N2 M t t i t id di ti l


118/174

N2: Metastasis to same-side mediastinal

and/or subcarinal (under the carina, or

tracheal ridge) lymph nodes.

N3: Metastasis to opposite-side mediastinal

or hilar nodes or to same- or opposite-side

scalene (neck/upper rib) or supracalvicular

(above collarbone) lymph nodes.

Metastasis


119/174

Metastasis

Lung Cancer with Invasion Into SpineThe state ofmetastasis (M) is defined as follows:

MX: Distant metastases cannot be assessed

M0: No distant metastases are found

M1: Distant metastases are present (this alsoincludes separate tumor nodules in a different lobeof lung on either side).

Lung

The Lungs are paired

elastic structures enclose

in the thoracic cage,

which is an airtightchamber, with distensible

walls.

Ventilation requiresmovement of the walls of

the thoracic cage and of

its floor, the diaphragm.

The effect of its movement is alternately to


124/174

The effect of its movement is alternately toincrease and decrease the capacity of the

chest, when the capacity of the chest isincreased, air enters through the trachea(inspiration) because of the loweredpressure within and inflates the lungs.

When the chest wall and diaphragmreturn to their previous positions

(expiration), the lungs recoil and force theair out through the bronchi and trachea.

I i ti d i th fi t thi d f


125/174

Inspiration occurs during the first third of

the respiratory cycle, expiration during thelatter two thirds.

The inspiratory phase of the respirationnormally requires energy, the expiratory

phase is normally passive requiring very

little energy.

Sometimes the cancer is diagnosed onroutine examination, and the patient hasno or minimal symptoms. Symptoms andsigns are dependent upon the location and

spread of the tumor.


132/174

Diagnostic Test

Chest X ray


133/174

Chest X ray

WHY IS ITGIVEN?

Are done to detect

size and position ofthe heart and

structural

abnormalities of the

lungs.

HOW DOES THE TEST WORK?


134/174

HOW DOESTHE TEST WORK?

Directs x-ray through the chest and ontofilm positioned behind the patients back.

As x-ray are directed to the patient, someare absorbed by the body and others passthrough the x-ray film.Areas of the bodythat absorb x-rays appear light on the x-

ray film. Dark areas on the film representx-ray that passed through the body.

WHAT TO DO?


135/174

WHATTO DO?

Explain the test to the patient and that the

patient will be asked to hold his or her

breath while the x-ray is taken.

Before the test, remove all jewelry,

zippers, hooks, and any metal on the part

of the body being x-rayed.

Bronchoscopy


136/174

Bronchoscopy

WHY IS IT DONE?

Bronchoscopy is used

to view the bronchialtree and to remove

foreign obstructions,

obtain tissues for

biopsy, or forsuctioning fluid.

HOW DOES IT WORK?


137/174

HOW DOES IT WORK?

The patient is anesthetized and a

bronchoscope is inserted into the patients

mouth and down the trachea and

bronchial tree. The bronchoscope containsa tiny video camera and probes that the

physician manipulates to perform the

procedure.

WHAT TO DO?


138/174

WHATTO DO?

Before the procedure

The patient must sign an informed consent for aninvasive procedure.

The patient is NPO for 8 hours except in an

emergency, to reduce chances of vomiting whenthe bronchoscope is passed down the throat.

During the procedure

Monitor vital signs, respiratory effort, and skincolor, cardiac monitor.

After the procedure:


139/174

After the procedure:

The patient remains nothing by mouth, (NPO)until the gag reflex returns to avoid aspiration.

Verify the cough and gag reflex returns.

Monitor respirations for rate, effort, use of

accessory muscles, and breath sounds. Monitor heart rate and respiratory status for

change.

Monitor sputum for blood due to irritation

within bronchi.

Pulmonary Angiography


140/174

Pulmonary Angiography

WHY IS IT DONE?

Provides a view of the

pulmonary circulatorysystem so that the

physician can

determine the

condition of bloodflow to the lungs.

HOW DOES THE TEST WORK?


141/174


Radiopaque dye is inserted into the

patients veins after a catheter has been

passed through the heart into the

pulmonary artery fluoroscopically. Theimage is watched on a screen as the dye

flows through he pulmonary circulatory

system.

WHAT TO DO?


142/174

WHATTO DO? Before the procedure:

Verify the patient is not allergic to contrast dye,iodine, or shellfish. If the patient is then eitheranother diagnostic study will be done, or the patient

will be premedicated for this test if no other test isdeemed appropriate. Diphenhydramine andprednisone may be given prior to the test to lessen orprevent an allergic reaction while closely monitoringthe patient.

The patient must sign an informed consent based oninstitutional policy.

Instruct the patient that a flushed feeling is commonhen the dye is injected intravenously.

During the procedure:


143/174

During the procedure:

Monitor patient for tolerance of procedureand possible reaction to dye.

Afte

roce

dure:

Monitor the insertion site for bleeding.

Sputum Culture and Sensitivity


144/174

p y

WHY IT IS DONE?

Sputum from the patient

is cultured to determinewhich, if any, bacteria is

contained in the sputum

and determine which

antibiotic kills thebacteria.



145/174

Sputum is collected from the patient in asterile container and sent to the lab where thesample is smeared in Petri dishes andincubated to grow the bacteria. Samples of

the bacteria are stained and examined undera microscope to identify the bacteria. Thesamples are checked periodically, but areusually given 72 hours to complete thetesting process. Once identified, bacteria are

exposed to known antibiotics to determinewhich antibiotic kills the bacteria.

WHATTO DO?


146/174

Before the test:

Use a sterile specimen container to determine that thebacteria that grow in the lab have come from the patientand not from contamination.

Collect sputum only and not saliva- there are bacterianaturally found in the mouth, so saliva samples willgrow bacteria in the lab even though it is not causingany infection.

After the test:

Sample needs to go to lab

Teach the patient:

How to properly obtain sputum sample.

Thoracentesis


147/174

WHY IT IS DONE?

Removal of fluid from

the pleural sac to

drain fluid or identifythe contents of the

fluid.



148/174

The patient either sits at the edge of the

bed or lies on the unaffected side. The

affected site is anesthetized.A needle

work is inserted into the plural sac andfluid is drained using a syringe.

WHATTO DO?


149/174

Befo

re the test:

The patient must sign an informed consent for aninvasive procedure.

Position the patient at the edge of the bed or lying

on the unaffected side with the head of the bedelevated 30 degrees.

During the test:

Monitor the patient for tolerance of the procedure. Monitor respiratory status for rate, effort, skin

color, use of accessory muscle, and breathsounds.


150/174

After the test:

Lay the patient on the affected side for 1 hourfollowing the procedure. This applies directpressure to the puncture site, reducing thechance of bleeding.

Monitor the injection site for leakage;reinforce dressing noted.

Monitor respiratory status for changes.

Pulmonary Function Test (PFT)


151/174

y ( )

WHY IS IT DONE?

This test assesses

the lungs ability to

move air. Monitorchange from normal

function; differentiate

obstructive from

restrictive disease.



152/174

The patient takes a deep breath. Thespirometer is inserted into the patients mouthand the patient breathes outward quickly atfull force until all air is expelled.A deep

breath is then taken in through themouthpiece and this process is repeatedthree times.A computer then calculates thelungs volume and vital capacity bymeasuring the amount of air moving in and

out. The force of the air flow is measured.The duration of time of exhalation ismeasured.

What to do?


153/174

Before the test:

The patient should not smoke prior to the

test. Smoking may have an effect on the

outcome of the test.

During the test:

Instruct the patient to take a deep breath

and then exhale completely into thespirometer followed by deep inhalation.


154/174

After the test: Administer bronchodilators after the initial

testing is gone and repeat the test if

indicated. This will show the effect ofbronchodilators on pulmonary function.

Albuterol or levalbuterol are typically used.

LungBiopsy


155/174

g p y

Why is it done?

Removal of a tissue

to be examined by thehistology lab for

abnormalities

How does the test work?


156/174

A tissue sample can be extracted by

inserting a needle through the chest and

into the lung or by using a bronchoscope.

A biopsy can also be performed as anopen procedure through the chest wall,

opening the lung to remove tissue

samples.

What to do?


157/174

Before the test:

The patient must sign an informed

consent. This is required for an invasive

procedure which will remove somethingfrom the body.

NPO for 8 hours to decrease the chance

of aspiration if done as an openprocedure.

During the test:


158/174

During the test:

Monitor vital signs, skin color, andrespiratory effort; cardiac monitor;

After the test:

Examine the incision site for bleeding. Monitor respiration for changes, potential

for pneumothorax development after a

piece of the lung has been removed.

Arterial Blood Gas (ABG)


159/174

Why is it done?

This determines the

patients ventilation,

tissue oxygenation,and acid-base status.

How does the test work?


160/174

Three top five milliliters of blood is sampled froman artery in a heparinized syringe. If the samplecannot be analyzed right away, it should be placedon ice.

The normal results are; pH 7.35-7.45

Pa02 80-100 mmHg

PaCO2 35-45 mmHg

HCO3 22-26 mEq/L

What to do?


161/174

Before the test:

Provide the lab with information on whetheror not patient is receiving supplementaloxygen or mechanical ventilation as well asthe amount of oxygen received or the settingof the ventilator. Oxygen supplementation atthe time of testing will be reported with theresults.

Note the patients temperature.Alteration intemperature may alter the results of the test.
