You are helping an EMT crew ventilate a patient with a bag-valve-mask device. What is the best action to take when you feel air coming from the mask?

When you feel air coming from the mask while using a bag-valve-mask (BVM) device, the best action to take is to hold the mask more firmly on the face. This response is crucial because if air is escaping from around the edges of the mask, it indicates that a proper seal has not been achieved. A tight seal is essential for effective ventilation, as it ensures that the air delivered from the bag enters the patient's airway instead of leaking out.

Achieving a good seal involves positioning the mask correctly on the patient's face and applying sufficient pressure to maintain contact with the skin without causing discomfort. Firmly holding the mask in place allows for optimal inflation of the lungs, which is critical in emergencies requiring respiratory support.

The effectiveness of ventilation directly correlates with how well the mask seals against the patient's face, making this action vital for patient care in situations requiring ventilatory assistance. Proper technique with the bag-valve-mask can significantly impact the patient's oxygenation and overall outcome.
