Explanation

The acronym AMBU stands for Artificial Manual Breathing Unit.
This term refers to a hand-held device, generically known as a Bag-Valve-Mask (BVM), used for manual resuscitation.
It is a fundamental tool in emergency situations to provide positive pressure ventilation to patients with respiratory failure or arrest.
The name originates from the company that first manufactured and marketed the device.
