Ambu Bag (Bag-Valve Mask – BVM) – Manual Resuscitator
An Ambu Bag, also known as a Bag-Valve Mask (BVM), is a manual resuscitation device used to provide positive pressure ventilation to patients who are unable to breathe adequately on their own. It is an essential tool in emergency medicine, anesthesia, and intensive care, helping to maintain oxygen supply and airway support until more advanced respiratory assistance is available.
Components & Design
The Ambu bag consists of the following key components:
- Self-Expanding Bag – A squeezable, air-filled bag that reinflates after compression.
- One-Way Valve – Prevents exhaled air from being inhaled back into the bag, ensuring fresh air or oxygen delivery.
- Face Mask – A soft, contoured mask that forms a seal around the patient’s nose and mouth.
- Oxygen Reservoir (Optional) – Connects to an oxygen source for increased oxygen concentration delivery.
- PEEP Valve (Optional) – Helps maintain positive airway pressure for patients requiring continuous ventilation support.
