POCKET MASK
The POCKET MASK is a barrier device used to provide rescue breathing.
It
has a one-way valve that prevents exchange of bacteria or viruses between
the victim and rescuer.
It is made of firm plastic with a cushioned rim and is
triangular in shape.
The rim creates a flexible seal around the victim’s nose
and mouth.
The mask fits over the victim’s mouth and nose.
The narrowest
portion of the mask is placed over the bridge of the victim’s nose.
APPLICATION OF THE POCKET MASK
Apply the rim of the mask first between the casualty’s lower lip and chin,
thus retracting the lower lip to keep the mouth open under the mask.
Position the end marked ‘nose’ over the casualty’s nose.
Use a C-Clamp to seal the mask completely.
Blow slowly into the mask until the chest rises.
After blowing, remove your mouth to allow exhalation.
After using the Pocket Mask, the user has to change the disposable replacement
valves with a new piece.
Also, the mask must be cleaned thoroughly with
alcohol swabs.
BREATHING DIFFICULTIES
The
Respiratory System
is the system of the body that deals with breathing.
The body breathes air from the atmosphere which is drawn in through the nose
or mouth and down through the trachea (windpipe).
The trachea is then divided
into two tubes called bronchi. As it progresses deeper into the lungs, the bronchi
branches out into smaller tubes called bronchioles, until finally they reach small
air sacs called alveoli. The alveoli are where the exchange of gases occurs. The
diaphragm is the breathing muscle that controls the breathing.The
LUNGS only
absorb 5-6%
oxygen inhaled from the 21% oxygen in atmospheric air and expel
the remaining oxygen together with carbon dioxide during exhalation.
