A bag valve mask, abbreviated to BVM and sometimes known by the proprietary name Ambu bag, is a hand-held device used to provide positive pressure ventilation to a patient who is not breathing or who is breathing inadequately. The device is a normal part of a resuscitation kit for trained professionals, such as ambulance crew. The BVM is frequently used in hospitals, and is an essential part of a crash cart. The device is used extensively in the operating room to ventilate an anaesthetised patient in the minutes before a mechanical ventilator is attached. The device is self-filling with air, although additional oxygen (O2) can be added.
Use of the BVM to ventilate a patient is frequently called "bagging" the patient. Bagging is regularly necessary in medical emergencies when the patient's breathing is insufficient (respiratory failure) or has ceased completely (respiratory arrest). The BVM resuscitator is used in order to manually provide mechanical ventilation in preference to mouth-to-mouth resuscitation (either direct or through an adjunct such as a pocket mask).

Famous quotes containing the words bag and/or mask:
“English general and singular terms, identity, quantification, and the whole bag of ontological tricks may be correlated with elements of the native language in any of various mutually incompatible ways, each compatible with all possible linguistic data, and none preferable to another save as favored by a rationalization of the native language that is simple and natural to us.”
—Willard Van Orman Quine (b. 1908)
“Mediocrity is the most effective mask a superior spirit can wear, because to the great majority, which is to say, to the mediocre, it will not suggest a disguise:—and yet it is precisely for their sake that he puts it on—so as not to arouse them, and, indeed, not infrequently to avoid this out of pity and benevolence.”
—Friedrich Nietzsche (1844–1900)
