The "mask" is often interchangeable for use on the mouth, on a tracheal tube, or even on an intubation tube. The bag is roughly the size and shape of an American football. When squeezed, air flows only through a valve leading to the mask, providing positive pressure to the lungs. When released, the valve to the mask closes, and another opens allowing air to flow into the bag to reinflate it as the bag regains its shape. The fill valve usually opens to the air, but an oxygen tube can also be attached to increase the partial pressure of oxygen.

  • 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.
