Non-rebreather mask

A Non-rebreather mask (pronunciation: non-ree-bree-thur mask) is a device used in medicine to assist in the delivery of oxygen in emergency situations.

Etymology

The term "Non-rebreather mask" is derived from its function. The mask is designed to allow a patient to "breathe in" oxygen, while not "re-breathing" the exhaled carbon dioxide, hence the term "non-rebreather."

Function

The Non-rebreather mask is typically used in emergency situations to provide high concentrations of oxygen to the patient. It consists of a face mask connected to a reservoir bag that is filled with a high concentration of oxygen. The mask has a one-way valve system which prevents the exhaled gases from being inhaled again, hence the name "non-rebreather."

Usage

Non-rebreather masks are used in situations where the patient requires a high concentration of oxygen, such as in cases of trauma, carbon monoxide poisoning, smoke inhalation, and severe pneumonia. They are also used in pre-hospital care settings, such as by paramedics and emergency medical technicians.
