How much volume does an ambu bag deliver?

AMBU bag must deliver between 700 and 1000 milliliters of air to the victim's lungs, but if oxygen is provided through the tubing and if the victim's chest rises with each inhalation (indicating that adequate amounts of air are reaching the lungs), 400 to 600 ml may still be adequate. Squeezing the bag once every 5 seconds for an adult or once every 3 seconds for an infant or child provides an adequate respiratory rate (12 respirations per minute in an adult and 20 per minute in a child or infant).
