A pocket mask, or pocket face mask or CPR mask, is a device used to safely deliver rescue breaths during a cardiac arrest or respiratory arrest. The pocket mask is a small device that can be carried on one's person. Air is administered to the patient when the emergency responder exhales through a one-way filter valve. Modern pocket masks have either a built in one-way valve or an attachable, disposable filter to protect the emergency responder from the patient's potentially infectious bodily substances, such as vomit or blood.
Many masks also have a built-in oxygen intake tube, allowing for administration of 50-60% oxygen. Without being hooked up to an external line, exhaled air from the provider can still provide sufficient oxygen to live, up to 16%. Earth's atmosphere consists of approximately 21% oxygen.
CPR stands for cardiopulmonary resuscitation. CPR helps to restore the partial flow of oxygenated blood to the brain and the heart, thus delaying tissue death and widening the window of opportunity to delay brain damage. During the emergency procedure the rescuer may provide breaths (ventilation) by mouth to mouth or utilizing a device (CPR face Mask) that pushes air into the victim's lungs. A CPR mask is a medical device used to safely deliver rescue breaths during a cardiac arrest or respiratory arrest. CPR mask is also named as pocket mask, or pocket face mask or CPR face mask, which is not as efficient as a bag valve mask, but in contrast to bag valve mask , the CPR mask has the advantages of easier portability and operation. The CPR mask is designed small and can be carried on one person.
The volume of gas passing through a flow sensor was measured at the face mask. This was a good estimate of the tidal volume entering and leaving the lung in this model. Gas leakage between the mask and mannequin was also measured. This occurred principally during inflation, although gas leakage during deflation was seen when the total leakage was large. A volume of gas that distended the mask but did not enter the lung was also measured.
Emergency Medical Products carries a complete line of CPR face Masks intended for emergency, first response, home or office use. We offer CPR face Masks that come in both hard case and soft case varieties.
