Which tool is acceptable for first responders to use when ventilating a patient?

When ventilating a patient, first responders have several tools at their disposal, of which both a pocket mask and a bag-valve-mask (BVM) device are acceptable and commonly used.

A pocket mask is designed to create a proper seal over the patient’s mouth and nose, allowing for effective ventilation while minimizing the risk of contamination from the patient. The mask helps ensure that the rescuer's breath can flow into the patient’s lungs without significant leakage, making it a suitable tool for assisted ventilation.

The bag-valve-mask device is another essential tool used for ventilating patients, particularly in emergencies where a higher volume of air is needed. The BVM consists of a self-expanding bag, a unidirectional valve, and a mask. When used correctly, it can deliver positive pressure ventilation, which is critical in situations where the patient is not breathing or has inadequate breathing.

Both tools are effective and serve different purposes based on the situation and the first responder's training. Therefore, the correct answer includes both options, highlighting that either can be used appropriately for ventilating patients based on the circumstances and the rescuer's capability.
