A Pocket BVM is a compact bag-valve-mask resuscitator designed to provide assisted ventilation to a patient who is not breathing adequately. It offers controlled airflow support in emergency situations when manual ventilation is required. When a patient is not breathing adequately, immediate assisted ventilation may be required while awaiting advanced medical care. The Pocket BVM is designed to provide manual ventilation support in a compact, portable format. Its reduced size makes it suitable for trauma kits, response bags, and environments where space and weight are limited, while still delivering the core function of a full-sized bag-valve-mask.
