What is the purpose of a CPR barrier mask?

The purpose of a CPR barrier mask primarily focuses on protecting the rescuer from potential infection during mouth-to-mouth resuscitation. This mask creates a physical barrier between the rescuer and the victim, significantly reducing the risk of transmitting infectious diseases. It is designed to allow airflow while filtering out exhaled air and any potential pathogens, thus creating a safer environment for performing rescue breathing.

While keeping the airway open is crucial during rescue operations, the primary role of the barrier mask is not about maintaining the airway, but rather about ensuring the safety of the person administering CPR. Furthermore, preventing water aspiration is not a function of the mask; this is generally related to drowning prevention measures. Lastly, while the barrier mask is beneficial during rescue breathing, it is not exclusively used for this purpose, as it can also provide protection during other aspects of CPR. Thus, its primary design and intent are closely aligned with infection control, making the emphasis on protection during mouth-to-mouth resuscitation a key reason for its use.
