What is Ambu bag used for?
An ambu bag is also called bag-valve mask (BVM). It is a portable device that is used to provide positive pressure ventilation to any individual who is taking insufficient or inefficient breaths. The product has a self-inflating bag, a one-way valve, a mask, and an oxygen reservoir. In case there is a respiratory emergency, then this device is used to manually ventilate the patient. One main indication for use of ambubags is respiratory failure because of hypercapnic hypercapnia.
