Ambu bag or generically as a manual resuscitator or resuscitator bag, is a handheld first aid tool used to deliver positive pressure ventilation to any subject who is not breathing or not breathing adequately. When performing CPR with an Ambu bag it is imperative to maintain a good mask seal. An Ambu bag consists of a self-inflating bag, a one-way valve, a mask, and an oxygen reservoir. Ambu bags can also be used to maintain airway patency, for example, in cases of severe asthma attacks or allergic reactions. Oxygen reservoir allows the user to deliver higher concentration of oxygen to the patient.

How to do CPR with an Ambu bag?

1. See if there is another way you can get a patient who is not breathing to breathe again. If this cannot be done, proceed with an Ambu bag.
2. Make sure the patient’s airway is clear of mucus and not blocked by any foreign bodies or their own tongue.
3. Tilt the patient’s head back slightly so that the nose is up. You can place something under their neck or shoulders to keep them in the right position, like a rolled up towel or jumper.
4. Ensure that the Ambu bag is sealed and connected properly. The bag should be connected to the oxygen tubing, and the tubing should be connected to the regulator on the tank.
5. Place the mask tightly over the patient’s mouth and nose.
6. Begin ventilations. Squeeze the Ambu bag hard enough to make the patient’s chest rise just as it would with a normal breath. Squeeze once every 2-3 seconds for a child, every 5-6 seconds for an adult. If the patient’s head is not rising, adjust their position and try again.
