Session 2Agenda- Physiology – Circulatory System

High Frequency

CIRCULATORY SYSTEM

CirculationYour body resembles

a large roadmap, There are routes or

“arteries” that take you to the “heart” of the city.

.

What is circulatory SystemThe circulatory system carries blood and dissolved

substances to and from different places in the body.

The Heart has the job of pumping these things around

the body

The Heart pumps blood and substances around the

body in tubes called blood vessels

The Heart and blood vessels together make up the

Circulatory System

3 Major Parts of the Circulatory system

Heart – pumps or pushes blood through body

Blood Vessels - routes blood travels

Blood – carries important “ *stuff ” through body

* Stuff – includes oxygen, food, & waste

Heart PhysiologyThe heart is the muscular organ of the circulatory

system that constantly pumps blood throughout

the body.

Approximately the size of a clenched fist.

The heart is composed of cardiac muscle

tissue that is very strong and able to contract and

relax rhythmically throughout a person's lifetime.

Heart –Right side pumps

deoxygenated blood.Left side pumps

oxygenated blood.

Blood volume – 4-5 litres- female5-6 litres – male

the right side of the

system

deals with

deoxygenated

blood.

the left side of the

system

deals with

oxygenated

blood.

The ARTERY

thick muscle and elastic

fibres

Arteries carry blood away from the heart.

the thick muscle can contract

to push the blood along.

The VEIN

Veins carry blood towards the heart.

thin muscle and elastic fibres

body muscles surround the veins so that when they contract to move the body, they also squeeze the veins and push the blood along the vessel.

The CAPILLARY

Capillaries link Arteries with Veins

the wall of a capillaryis only one cell thick

The exchange of materials between the blood and the body can only occur through capillaries.

Your Blood is made of

Red Blood Cells

They carry oxygen to all parts of the body

A straw-coloured liquid that carries the cells and the platelets which help blood clot.

• carbon dioxide

• glucose

• amino acids

• proteins

• minerals

• vitamins

• hormones

• waste materials like urea.

It also contains useful things like;

PlasmaLiquid part of blood

White Blood CellsFight and kill germs that may enter your bloodstream

PlateletsForm “scabs” when you cut yourself

Helps stop the bleeding

HIGH FREQUENCY

1906 1918 2008

High frequency current moves

backward and forward at high speed.

Works on alternating or oscillating

current.

Frequency measured at 100 000-

250 000 hertz.

Used for both beauty and hair

treatments.

High frequency current is also called

“Tesla current” (pioneer Nikola Tesla).

Types of High Frequency

High voltage used for beauty treatments.

Lower voltage used by the Dermatologist for Epiliation.

The Machine….

ElectrodesElectrodes are made up of glasses.

It has metal cap, which is a push fit into

electrode.

Electrodes are available in different sizes and

shapes.

Types of ElectrodesMushroomSpot knobSaturatorNeck shapeComb shape

Electrodes- ColorElectrodes contains gases:

Neon – Orange

Argon – Violet

Mercury - blue

Direct High FrequencyThe electrode is placed directly on the skin

The therapist holds electrode in contact with the

treatment area and gently moves it over the skin.

The electrode discharges its high frequency

energy directly into the skin at the point of

contact.

There are 2 Ways of using direct High Frequency

This method uses a

glass electrode, which

is moved slowly over

the skin; it is known as

Effluvation

SPARKING

FORMATION OF OZONE-

When the high frequency current is passed

through oxygen, it produces ozone.

This occurs between the electrode and the skin

and more intensely when the electrode is lifted

very slightly off the face to ‘spark’ pustules.

 

Indication GreasyAcne prone skin Oily CombinationDry skin

Benefits/ Effects :Warms the skin’s tissue

Stimulating effect of nerves

Vasodilatation resulting in erythema

Increases the blood flow

Improves metabolism

Increases glandular ( sebaceous glands) activity

Generates the ozone which has a germicidal action

Drying effect

PRODUCTTalc

Medicated powder

Boric powder

Ozone cream

Duration – 6 to 8 min.

Indirect High FrequencyWhen the current is switched on, it flows

through the saturator and charges the

client, the therapist massages the client’s

face and the current discharges from the

face to the massaging fingers.

The therapist is a part of the circuit.

Indication: Dry, dehydrated skin

Poor circulation

Tired skin

Relaxes tense muscles

Mature skin

Effects :Warmth is produced in the superficial tissues

Improves circulation

Improving metabolic activity.

Mild and slow massage has a sedative effect.

Thus relaxing tense tissues.

Desquamation

PRODUCTCream – Soothing and relaxing effect

Duration – 6 to 8 min.

CONTRAINDICATION Acne roseacea

Any cuts and abrasions

Headache or migraine

Vascular condition

Hyper sensitive skin

Excessive metal filling

Hairy client

Skin diseases and disorders

Pregnancy

Lack of tactile sensation

Systemic Edema

PRECAUTIONRemove jewellery and metal.

Ensure that the client does not touch the metal.

Warn the client about the machine’s noise.

Always keep the electrode in contact with the skin.

Do not spark more than quarter inch away from the skin

surface, as this is destructive to tissue.

The saturator must be held by the client tightly.

Put talc on the client’s hand before placing the electrode.

Always keep one hand in the client’s and keep it moving,

while the other hand intensifies the current.

DANGERSThe main danger is shock –

By touching faulty apparatus

Using gel or water based product

Touching metal

Lifting the electrode off the skin during treatment

Placing the electrode on the skin with high intensity

Sparking from a great distance and a long duration.
