A non-rebreather mask is a special medical device that helps provide you with oxygen in emergencies. These masks help people who can still breathe on their own but need a lot of extra oxygen. The non-rebreather oxygen mask is a medical device used for the delivery of high concentrations of oxygen to patients who require or are at risk of severe hypoxemia (low blood oxygen levels).
1. Design:
- The non-rebreather mask is a type of oxygen mask designed to
cover the nose and mouth of the patient.
- It is made from medical-grade PVC (polyvinyl chloride), which is
a flexible and transparent material.
2. Reservoir Bag:
- One of the distinctive features of the non-rebreather mask is the
presence of a reservoir bag attached to the mask.
- The reservoir bag allows the accumulation of oxygen during
inhalation, preventing the patient from inhaling exhaled air and
increasing the delivered oxygen concentration.
3. One-Way Valves:
- The mask typically includes one-way valves between the mask and
the reservoir bag to ensure that the patient breathes in oxygen
from the reservoir rather than inhaling room air or exhaled air.
4. Adjustable Nose Clip:
- Some non-rebreather masks have an adjustable nose clip to secure
the mask comfortably on the patient's face.
5. Elastic Strap:
- An elastic strap is usually included to secure the mask around
the patient's head, ensuring a proper fit.
6. Oxygen Flow Rate:
- The flow of oxygen is set by adjusting the oxygen source, such as
an oxygen concentrator or cylinder, to achieve the prescribed
oxygen flow rate.
Non-rebreather masks are commonly used in emergency medical situations, intensive care units, and other healthcare settings where high concentrations of oxygen are required. It's important for healthcare professionals to ensure proper mask fit, monitor the patient's response, and adjust the oxygen flow rate as needed.

Why is it called non-rebreather mask?
The non-rebreather mask gets its name from its design and function, which is aimed at preventing the patient from inhaling exhaled air or room air during the breathing cycle. The key features of the non-rebreather mask contribute to the prevention of rebreathing, distinguishing it from other types of oxygen masks.
Here's why it's called a non-rebreather mask:
1. Prevents Rebreathing:
- The primary purpose of the non-rebreather mask is to deliver high
concentrations of oxygen to the patient while preventing the
inhalation of exhaled air.
- The mask includes a reservoir bag that collects and stores oxygen
during inhalation. This reservoir bag is inflated with oxygen and
helps minimize the intake of exhaled or ambient air.
2. One-Way Valves:
- The non-rebreather mask is equipped with one-way valves that
allow the patient to inhale oxygen from the reservoir bag without
drawing in air from the surrounding environment.
- Exhaled air is directed away from the patient, reducing the risk
of rebreathing carbon dioxide.
3. Open Exhalation Ports:
- The mask design includes open exhalation ports or vents that
allow exhaled air to escape, preventing its accumulation in the
mask and reducing the likelihood of rebreathing.
The term "non-rebreather" emphasizes that this type of mask is designed to avoid the rebreathing of exhaled air, which can lead to a decrease in oxygen concentration and an increase in carbon dioxide levels. This is particularly important when higher concentrations of oxygen are needed, such as in emergency situations or for patients with severe hypoxemia.
This mask is called “non-rebreather” because, when you're using it, you're unable to inhale anything you exhale. It allows you to breathe only pure oxygen. A non-rebreather mask typically delivers 70 to 100 percent oxygen.
Which patient needs non-rebreather mask?
The non-rebreather mask is typically used for patients who require high concentrations of oxygen and are at risk of severe hypoxemia (low blood oxygen levels). It is commonly employed in various medical settings, including emergency rooms, intensive care units, and during certain medical procedures. The non-rebreather mask may be indicated for the following types of patients:
1. Hypoxemic Patients:
- Patients with critically low blood oxygen levels (hypoxemia) may
benefit from the high concentrations of oxygen delivered by a
non-rebreather mask.
2. Respiratory Distress or Failure:
- Individuals experiencing respiratory distress or respiratory
failure may require increased levels of supplemental oxygen to
support their breathing and improve oxygenation.
3. Emergency Situations:
- The non-rebreather mask is often used in emergency medical
situations where rapid and effective oxygen delivery is crucial,
such as in cases of severe trauma, cardiac emergencies, or acute
respiratory distress.
4. Post-Surgical Patients:
- After certain surgeries, patients may be at risk of decreased
oxygenation. The non-rebreather mask can be utilized to provide a
higher concentration of oxygen during the postoperative recovery
period.
5. Severe Respiratory Conditions:
- Patients with severe respiratory conditions, such as acute
exacerbations of chronic obstructive pulmonary disease (COPD) or
pneumonia, may require the high oxygen concentrations delivered by
a non-rebreather mask.
6. In Conjunction with Nebulized Medications:
- Non-rebreather masks are sometimes used in conjunction with
nebulized medications to deliver both oxygen therapy and
aerosolized medications to patients with respiratory conditions.
