The Adult Ambu Bag, also known as a manual resuscitator or self-inflating bag, is a crucial medical device used for manual ventilation during emergencies. Designed for adults, it consists of a self-expanding bag, a unidirectional valve, and a face mask. Medical professionals utilize the Ambu Bag to manually deliver positive pressure ventilation to individuals experiencing respiratory distress or failure. With a squeezable bag and adjustable components, it allows for controlled airflow into the patient's lungs. The Adult Ambu Bag is an essential tool in situations where immediate and temporary respiratory support is required, such as in pre-hospital care, emergency rooms, and critical care settings.
