A bag valve mask (BVM), sometimes known by the proprietary name Ambu bag or generically as a manual resuscitator or "self-inflating bag", is a hand-held device commonly used to provide positive pressure ventilation to patients who are not breathing or not breathing adequately.
A resuscitator is a device using positive pressure to inflate the lungs of an unconscious person who is not breathing, in order to keep them oxygenated and alive. [citation needed] There are three basic types: a manual version (also known as a bag valve mask) consisting of a mask and a large hand-squeezed plastic bulb using ambient air, or with supplemental oxygen from a high-pressure tank.
Mechanical ventilation is a method to mechanically assist or replace spontaneous breathing. [8] This involves the use of ventilator assisted by a registered nurse, physician, physician assistant, respiratory therapist, paramedic, or other suitable person compressing a bag valve mask.
The device must have a pressure relief valve that opens at 60cm of water pressure to avoid over ventilation and trauma to the lungs. The (FROPVD) is contraindicated in adult patients with potential chest trauma and all children. Note: ( In cases with an apneic patient the best results will be achieved using the Two person bag-valve-mask technique.)
Ventilators may be computerized microprocessor-controlled machines, but patients can also be ventilated with a simple, hand-operated bag valve mask. Ventilators are chiefly used in intensive-care medicine, home care, and emergency medicine (as standalone units) and in anesthesiology (as a component of an anesthesia machine).
