Bag-Valve-Mask (BVM)

A Bag-Valve-Mask (BVM) is a medical device used to provide positive pressure ventilation to individuals who are not breathing or not breathing adequately. It consists of a self-expanding bag, a unidirectional valve, and a face mask. When squeezed, the bag forces air into the patient's lungs through the mask, while the valve prevents air from escaping back out. BVMs are commonly used by healthcare professionals in emergencies to support breathing until further medical help is available. Proper technique is essential for effective use and to ensure the patient receives enough oxygen.
