An ambu bag, also known as a manual resuscitator or bag valve mask (BVM), is a medical device used to assist a person who is unable to breathe on their own. It is a soft, compressible bag that fix to a face mask. When a doctor or nurse presses the bag, it forces air into the patient's lungs.
Ambu bags are used in hospitals, ambulances, and during emergency situations like CPR (cardiopulmonary resuscitation). It's very important for patients who have stopped breathing or who are suffering from breathing problems. Some Ambu bags are made of silicone and can be reused after proper cleaning.
This simple device can save lives by providing the brain and body with the necessary oxygen.
