Ambu Bags for CPR - What, Why, and How to do CPR with an Ambu Bag
An Ambu bag, or bag-valve-mask (BVM), is a handheld medical device that manually delivers positive pressure ventilation (air or oxygen) to a patient with inadequate or no spontaneous breathing. It consists of a self-inflating bag, a one-way valve, and a mask, used to support respiration during emergencies like cardiac arrest or respiratory distress by forcing air into the lungs. Proper use involves securing a mask to the patient's face, establishing a good seal, and squeezing the bag at an appropriate rate to achieve visible chest rise, all while continuing till professional medical help arrives.
