What is the function of a resuscitation mask?

The function of a resuscitation mask is primarily to ventilate a non-breathing individual while ensuring that there is no direct mouth-to-mouth contact between the rescuer and the casualty. This is important for both the safety of the rescuer and the effectiveness of the ventilation process.

Resuscitation masks create a seal around the mouth and nose of the victim, allowing the rescuer to deliver breaths while minimizing the risk of transmitting infectious diseases. The design of this mask facilitates the proper delivery of air into the lungs, which is essential in performing effective rescue breaths. The presence of a one-way valve further aids in preventing exhaled air from escaping back towards the rescuer, enhancing safety and hygiene during such critical interventions.

Reasons why the other options do not apply include the fact that resuscitation masks are not designed for administering medications, nor do they provide oxygen directly to a patient. Additionally, while CPR may involve checking for a pulse, the primary role of a resuscitation mask focuses on ventilation, not bypassing the pulse check.
