For providing emergency artificial respiration for resuscitation this consists of a bag, valve and facepiece. The bag remains inflated in its resting state and when squeezed closes the expiratory port and inflates the patient's lungs. When the bag is released it automatically re-inflates with fresh air and the patients expired air passes out to atmosphere via the expiratory valve. Oxygen may be supplied to the bag via a small tube and valve at one end of the bag. The facepiece is usually transparent so that vomit can be seen. A similar type of respirator is the Air Viva.
