Bromed CPR Mask is a device used to safely deliver rescue breaths during a cardiac arrest or respiratory arrest. The CPR 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 CPR 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. Same way CPR face shield, a barrier with a filter valve can also suffice the same purposes.
