NRBM Full Form

NRBM Full Form – non-rebreather mask, Non-rebreather masks are supplied air via a two-stage filtering system. The first stage is composed of an inlet filter, which pulls all particles larger than 4 microns out of the air stream, and under-mask filters that removes small particles between 1 and 3 microns from the air passing through it. The second stage is composed of exhalation valves, which vent exhaled gases to ambient providing positive pressure ventilation for patient’s lungs during general anesthesia.

They were one of the most commonly used devices for delivering oxygen to surgical patients before standard anesthesia masks became available. Their use before standard masks became available is due primarily to their lowered resistance (less effort by health care provider).

  1. Non-rebreather masks are used in situations where there is a need for oxygen, but the person cannot use their own lungs.
  2. They are often used on patients that have difficulty breathing or are having an asthma attack.
  3. The non-rebreather mask has one tube which goes into the mouth and another tube which provides air from a tank or machine.
  4. These masks can be placed over the nose and mouth to provide fresh air to someone who isn’t able to breathe well enough on their own.
  5. A non-rebreather mask should not be worn by anyone who has trouble swallowing due to risk of aspirating fluids into the lungs.
  6. Non-rebreather masks should only be worn when necessary as they do not allow for humidity like regular respirator masks do.


  1. Non-rebreather masks are designed to be worn over the nose and mouth, while BiPAP is a machine that delivers air through a tube.
  2. The non-rebreather mask has more of an open design than BiPAP because it doesn’t use tubes.
  3. A non-rebreather mask can only be used with people who have some lung function, but BiPAP can be used by any person.
  4. You may need to adjust settings for your specific needs with both devices.
  5. Patients should talk with their doctor before deciding on which device they want to use.
  6. It’s important to know what type of sleep apnea you have before choosing between these two devices.

NRBM Mask Uses

  1. Non-rebreather masks are used for anesthesia, as well as other medical purposes.
  2. It is also used to protect the patient’s airway in case of an emergency.
  3. Non-rebreather mask can be used by people who have difficulty breathing or swallowing.
  4. The most common use for non-rebreather mask is during surgery procedures like open heart surgery and neurosurgery.
  5. They provide a way to deliver gas (oxygen) that is more efficient than traditional face masks because it does not require the person wearing one to breathe into them before they start delivering oxygen.
  6. Because they do not cover the nose, they allow patients to speak without removing them from their mouth.
