What is the primary purpose of using a BVM?

The primary purpose of using a Bag-Valve-Mask (BVM) is to assist with ventilation in patients who are unable to breathe adequately on their own. When a patient is in respiratory distress or has stopped breathing, the BVM allows a rescuer to deliver positive pressure ventilation, ensuring that oxygen is effectively provided to the lungs. This is crucial in situations like cardiac arrest or severe respiratory failure, where maintaining oxygenation is vital for the patient's survival.

Using a BVM requires a proper seal over the patient's mouth and nose, which enables the rescuer to deliver breaths effectively. This device can be coupled with supplemental oxygen to enhance the oxygen concentration delivered to the patient, but its primary function remains assisting with the mechanical process of ventilation. In life-threatening situations, efficient ventilation is necessary to keep vital organs perfused with oxygen-rich blood.

Other choices focus on different aspects of patient care, such as medication delivery and CPR techniques, which are important but not the main goal of the BVM. The device's specific design and function prioritize helping patients breathe when they are unable to do so effectively on their own.
