Symptoms / Chief complaintCough




Chest pain (chest tightness / discomfort)


CoughType Dry, Productive , Short, Brassy, Bovine ,Barking , whooping, Cough syncope, Nocturnal, Drug induced

Onset & Duration

Pattern : activities, time of day, weather


Timing and associated features

Causes of cough: Normal chest X-rayAbnormal chestX-ray

Acute cough(8 weeks)GERD, Asthma, Post viral bronchial hyper reactivity, Rhinitis/sinusitis, Cigarette smokingDrugs (ACE inhibitors, Irritant dusts/fumes) Lung tumor, TB, Interstitial lung disease, BronchiectasisSputumSputum is mucus produced from the respiratory tract. The normal lung produces about 100 ml of clear sputum each day, which is transported to the oropharynx and swallowed

Dyspnoea (breathlessness) is undue awareness of breathing and is normal with strenuous physical exercise.

Patients use terms such as shortness of breath,difficulty getting enough air in, or tiredness

Grades: M R C classification:

Grade I: Breathless when hurrying on the level or walking up a slight hill

Grade II: Breathlessness when walking with people of own age or on level ground

Grade III: Walks slower than peers, or stops when walking on the flat at own pace

Grade IV: Stops after walking 100 metres, or a few minutes, on the level

Grade V: Too breathless to leave the house (Too breathless to wash or dress Sherwood )Modes of onset, duration and progressionMinutes Pulmonary thromboembolismPneumothorax, Asthma, Inhaled foreign bodyAcute left ventricular failureHours to daysPneumonia, Asthma , Exacerbation of COPD, LHFWeeks to monthsAnaemia, Pleural effusion, Respiratory neuromuscular disordersMonths to yearsCOPD, Pulmonary fibrosis, TB, Muscle weakness


Orthopnoea :Breathlessness when lying flat (LVF)

Platypnoea: Breathlessness on sitting up with relief on lying down right-to-left shunting

Trepopnoea : Breathlessness when lying on one side is due to unilateral lung disease dilated Cardiomyopathy13Paroxysmal nocturnal dyspnoea : wakes the patient from sleep

Breathlessness improving at weekends or holidays occupational asthma.

Spine AbmormalitesKyphosis: Causes the patient to be bent forward.

Ankylosing spondylitis: Diminished volume of lung & capacity of the chest

Scoliosis: spine is curved to either the left or right.

Type of breathing

RateNormal: 14-18 breaths/minType of breathingPulse : Respiratory rate (4:1)Tachyponea:Nervousness, fever, hypoxia, exertionAPE, Pneumonia, Pul. Emobolism, ARDS, Metabolic acidosisBradypnoea: Alkalosis, Hypothyroidism, raised ICTHyperpnoea:Acidosis, brainstem lesion, Hysteria


Inspiration: by the contraction Of the external intercostal muscles and the diaphragm

Expiration: Depends upon the elastic recoil of the lungsAbnormal breathing patternsCheyne-Stokes respirations

Hyperpnoea followed by apnoeaperiods of respirations during which the tidal volume starts shallow and gets progressively deeper, and then gets progressively shallower. Causes: strokes, traumatic brain injuries, brain tumors, CO poisoning, and metabolic encephalopathy, normal side-effect of morphine administration.

Kussmaul's Breathing:

Labored hyperventilation characterized by a deep and rapid respiratory pattern.

Causes: late stages of a severe metabolic acidosis (DKA).

Apneustic Breathing:

prolonged inspiratory phases with each breathe, followed by a prolonged expiratory phase

causes: lesion to the upper part of the pons

Ataxic Breathing:

A completely irregular breathing pattern with irregular pauses and unpredictable periods of apnea.

Cause: lesion to the medulla oblongata secondary to trauma or stroke.

very poor prognosis.

Biot's Breathing

Apnoea between several shallow or few deep inspirations

It is very similar to Cheyen-Stokes except the spontaneous t
