Resuscitation. Doctor using an "Ambu bag" to resuscitate an unconscious woman. The Ambu bag (centre) is made up of a mask connected to a bag by a one-way valve. Oxygen is supplied to the bag. Squeezing the bag forces the mixture of air and oxygen into the patient's lungs, maintaining oxygenation of the blood and stimulating natural breathing.
