BVM ventilation is a critical skill for emergency providers. Most oftenly, a BVM is an emergency procedure carried to tide over until intubation is done.

Use of manual resuscitators to ventilate a patient is frequently called "bagging" the patient and is regularly necessary in medical emergencies when the patient's breathing is insufficient (respiratory failure) or has ceased completely (respiratory arrest). Use of the manual resuscitator force-feeds air or oxygen into the lungs in order to inflate them under pressure, thus constituting a means to manually provide positive-pressure ventilation. It is used by professional rescuers in preference to mouth-to-mouth ventilation, either directly or through an adjunct such as a pocket mask (rescue CPR mask).

Winner ambu bag including the disposable ambu bag and reusable ambu bag are the most demanding item in the market. There are some other items such as Rescue resuscitation mask cpr, Ventilation CPAP mask for sleep apnoea treatment etc.
