- Provide a barrier between the rescuer and the victim's mouth and nose during rescue breathing.
- Allow for one-way flow of air, reducing the risk of cross-contamination.
- Portable and easy to use in emergencies.

b.) Bag valve mask:

- Manual resuscitator used to provide ventilation assistance to a victim who is not breathing or has inadequate breathing.
- Consists of a self-inflating bag, a face mask, and a valve system that allows for controlled administration of air.
- Requires more advanced training and practice to use effectively.
