prevent the spread of disease or illness
It is commonly referred to as a CPR Mask, or even an ambu-bag.
Dr. Peter Safar invented the CPR mouth barrier.
30 compressions 2 breaths. Per 2010 AHA guidelines. Compression only CPR can be performed if no barrier device is present.
When CPR or rescue breathing is performed, a breathing barrier is used to prevent such infections; the clap is not transferred via CPR even if a barrier is not used.
1 rescuer CPR for infant is 30 compressions to 1 breath.
There really shouldn't be any doubt in your mind about using a barrier device. The purpose of a barrier device is to reduce the risk of transmission of disease between you and the victim. Barrier devices by definition are tools that reduce that risk while still enabling you to render quality care. The only 'con' (and it is so minor that I hesitate to even acknowledge it) that I can think of is the few seconds it takes you to put a barrier device in place, but it is more than worth the time for the safety of your victim and yourself.
You could just do compressions at a speed of 100/minute, or you could do the 'mouth to mouth' part without the barrier. It all depends on you and how well you know the person. Either way, make sure EMS has been called!
If the infection wound is around the mouth area, you can be infected with staph from giving CPR. Using a breathing barrier (CPR mask) minimizes risks of transfer.
To prevent transmission of body fluids from victim to rescuer and from rescuer to victim.
It is possible to get an infectious disease from performing CPR. The risk is low, but there is a risk. That is why the ARC and AHA advise the use of a breathing barrier when performing CPR (even during class practice on the mannequin).
Breathing is required for CPR. You can use a breathing barrier such as a mask; or use a bag valve mask for the breaths. Mouth to mouth, per se, is not recommended.
