A bag-valve-mask (BVM) is specifically designed to assist with ventilation in patients who are unable to maintain their own airway or breathe adequately on their own. When a patient cannot independently manage their airway due to conditions such as decreased level of consciousness, severe respiratory distress, or obstructions, the use of a BVM becomes critical. This device allows for adequate ventilation and delivery of oxygen, ensuring that the patient receives the necessary support to maintain oxygenation and prevent hypoxia.

In scenarios where a patient is fully conscious, long-term oxygen therapy is needed, or dealing with allergic reactions, other interventions are typically more appropriate. For instance, a fully conscious patient may have the ability to protect their own airway and breathe adequately without assistance, making the use of a BVM unnecessary. Similarly, long-term oxygen therapy usually involves devices like nasal cannulas or oxygen masks, which are more suitable for ongoing respiratory support. In the case of allergic reactions, while the patient may experience respiratory distress, the initial response is often focused on addressing the allergic reaction itself, potentially with medications before considering the need for a BVM.
