CIRCULATORY SYSTEM
![Page 3: Use of High Frequency Machine for Facial Treatments. This knowledge was shared & demonstrated by LTA School Of beauty in one of its PG CIDESCO Lecture Series](https://reader033.fdocuments.us/reader033/viewer/2022061206/54824fb1b4af9f3e4e8b4704/html5/thumbnails/3.jpg)
CirculationYour body resembles
a large roadmap, There are routes or
“arteries” that take you to the “heart” of the city.
![Page 4: Use of High Frequency Machine for Facial Treatments. This knowledge was shared & demonstrated by LTA School Of beauty in one of its PG CIDESCO Lecture Series](https://reader033.fdocuments.us/reader033/viewer/2022061206/54824fb1b4af9f3e4e8b4704/html5/thumbnails/4.jpg)
.
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
![Page 5: Use of High Frequency Machine for Facial Treatments. This knowledge was shared & demonstrated by LTA School Of beauty in one of its PG CIDESCO Lecture Series](https://reader033.fdocuments.us/reader033/viewer/2022061206/54824fb1b4af9f3e4e8b4704/html5/thumbnails/5.jpg)
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.

The ARTERY
thick muscle and elastic
fibres
Arteries carry blood away from the heart.
the thick muscle can contract
to push the blood along.
![Page 13: Use of High Frequency Machine for Facial Treatments. This knowledge was shared & demonstrated by LTA School Of beauty in one of its PG CIDESCO Lecture Series](https://reader033.fdocuments.us/reader033/viewer/2022061206/54824fb1b4af9f3e4e8b4704/html5/thumbnails/13.jpg)
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.

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).

It has metal cap, which is a push fit into
electrode.
Electrodes are available in different sizes and
shapes.

Electrodes- ColorElectrodes contains gases:
Neon – Orange
Argon – Violet
Mercury - blue
![Page 29: Use of High Frequency Machine for Facial Treatments. This knowledge was shared & demonstrated by LTA School Of beauty in one of its PG CIDESCO Lecture Series](https://reader033.fdocuments.us/reader033/viewer/2022061206/54824fb1b4af9f3e4e8b4704/html5/thumbnails/29.jpg)
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.
![Page 30: Use of High Frequency Machine for Facial Treatments. This knowledge was shared & demonstrated by LTA School Of beauty in one of its PG CIDESCO Lecture Series](https://reader033.fdocuments.us/reader033/viewer/2022061206/54824fb1b4af9f3e4e8b4704/html5/thumbnails/30.jpg)
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
![Page 31: Use of High Frequency Machine for Facial Treatments. This knowledge was shared & demonstrated by LTA School Of beauty in one of its PG CIDESCO Lecture Series](https://reader033.fdocuments.us/reader033/viewer/2022061206/54824fb1b4af9f3e4e8b4704/html5/thumbnails/31.jpg)
SPARKING
![Page 32: Use of High Frequency Machine for Facial Treatments. This knowledge was shared & demonstrated by LTA School Of beauty in one of its PG CIDESCO Lecture Series](https://reader033.fdocuments.us/reader033/viewer/2022061206/54824fb1b4af9f3e4e8b4704/html5/thumbnails/32.jpg)
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.

![Page 36: Use of High Frequency Machine for Facial Treatments. This knowledge was shared & demonstrated by LTA School Of beauty in one of its PG CIDESCO Lecture Series](https://reader033.fdocuments.us/reader033/viewer/2022061206/54824fb1b4af9f3e4e8b4704/html5/thumbnails/36.jpg)
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.

![Page 41: Use of High Frequency Machine for Facial Treatments. This knowledge was shared & demonstrated by LTA School Of beauty in one of its PG CIDESCO Lecture Series](https://reader033.fdocuments.us/reader033/viewer/2022061206/54824fb1b4af9f3e4e8b4704/html5/thumbnails/41.jpg)
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.

By touching faulty apparatus
Using gel or water based product
Touching metal
