AMBU BAG

An Ambu bag, also known as a bag-valve-mask (BVM), is a medical device used to provide positive pressure ventilation to a patient who is not breathing adequately or has inadequate oxygenation. It consists of a flexible bag made of silicone or other materials, a face mask, and a valve system that allows the bag to be squeezed manually to deliver air or oxygen to the patient's lungs.

• Provide assisted ventilation to people who are either not breathing or are having trouble breathing.
•  The bag needs to be compressed to force a volume of air into the lungs.
• Consists of a bag, adapter and one-way valve. The bag is the main part of the device.
•  It can be attached directly to an endotracheal tube or a mask using the adapter.
•  The bag also has a one-way valve which allows the oxygen to flow to the patient and prevents the patient from breathing in his exhaled air.
•  Some bags may have a reservoir, which increases the amount of oxygen the patient receives.
