What does BVM stand for in Basic Life Support terminology?

The term BVM refers to "Bag Valve Mask," which is a crucial piece of equipment used in Basic Life Support (BLS) to provide positive pressure ventilation to patients who are not breathing adequately or at all. This device consists of a self-expanding bag, a unidirectional valve, and a mask that fits over the patient's nose and mouth.

Using a BVM helps to ensure that oxygen is effectively delivered to the patient's lungs, which is vital in preventing hypoxia and helping to maintain adequate oxygen saturation levels during a medical emergency. The design allows the rescuer to seal the mask tightly against the patient's face while compressing the bag to deliver the necessary breaths, making it a highly efficient tool in resuscitation efforts.

Understanding the function and proper use of a Bag Valve Mask is fundamental for anyone trained in Basic Life Support, as it directly impacts the likelihood of patient survival during critical situations.
