What type of mask allows ventilation of a non-breathing guest without using solely a resuscitation mask?

The Bag Valve Mask is specifically designed for providing positive pressure ventilation to a non-breathing guest. This device consists of a self-expanding bag and a unidirectional valve that prevents exhaled air from re-entering the bag. When used correctly, it allows a rescuer to effectively deliver oxygen to someone who is not breathing by creating a seal over the person's face and squeezing the bag.

In emergency situations, utilizing a Bag Valve Mask can significantly improve the chance of resuscitating an individual by ensuring that they receive adequate ventilation. This is essential because, in cases of respiratory arrest or cardiopulmonary arrest, restoring adequate breathing is a critical objective. The Bag Valve Mask can be used in conjunction with supplemental oxygen, further enhancing its effectiveness.

Other options, while useful in different contexts, do not serve the same function as a Bag Valve Mask for providing assisted ventilation. The face shield is primarily designed to protect the rescuer during CPR but does not facilitate adequate ventilation on its own. A standard mask does not typically provide the required ventilatory support, and a non-rebreather mask is used to deliver high concentrations of oxygen, but it is unsuitable for assisting in ventilation for a non-breathing guest. Thus, the Bag Valve Mask
