What does BVM stand for in a medical context?

In a medical context, BVM stands for Bag Valve Mask. This device is used to provide positive pressure ventilation to individuals who are not breathing adequately on their own. The BVM consists of a self-expanding bag, a unidirectional valve, and a face mask. When the bag is squeezed, air flows through the valve and into the patient's lungs, which can be critical in emergency situations such as respiratory failure or cardiac arrest.

The design of the BVM allows for controlled administration of oxygen directly into the lungs, making it an essential tool for lifeguards and other first responders trained in CPR. Mastery of its use is crucial, as proper technique can significantly enhance the likelihood of maintaining adequate oxygenation of a patient until further medical help arrives.
