bag-mask ventilation
Manual ventilation technique using a self-inflating bag and face mask to deliver positive pressure breaths during emergencies or procedures.
Full Definition
Bag-mask ventilation, also known as bag-valve-mask (BVM) ventilation, is a fundamental respiratory therapy technique used to provide manual positive pressure ventilation. The device consists of a self-inflating bag connected to a one-way valve system and a face mask that forms a seal over the patient's nose and mouth. This technique is commonly employed during cardiopulmonary resuscitation, anesthesia induction, or when mechanical ventilation is temporarily unavailable. Proper technique requires maintaining an adequate mask seal while delivering appropriate tidal volumes at correct rates. The method allows for immediate ventilatory support while more definitive airway management is established.
Usage
Usage note: Often abbreviated as BVM in clinical documentation.
