Oxygen masks may cover only the nose and mouth (oral nasal mask) or the entire face (full-face mask). They may be made of plastic , silicone , or rubber . In certain circumstances, oxygen may be delivered via a nasal cannula instead of a mask.
A nasal cannula is generally used wherever small amounts of supplemental oxygen are required, without rigid control of respiration, such as in oxygen therapy. Most cannulae can only provide oxygen at low flow rates—up to 5 litres per minute (L/min)—delivering an oxygen concentration of 28–44%.
A non-rebreather mask (NRB, non-rebreather, non-rebreather facemask, etc.) is a device used in medicine to assist in the delivery of oxygen therapy. A NRB requires that the patient can breathe unassisted, but unlike a low-flow nasal cannula , the NRB allows for the delivery of higher concentrations of oxygen .
The simple face mask can deliver higher flow rates than nasal cannula (6–10 liters per minute) for an FiO2 of 30- 60% oxygen. Nasal cannula and simple face masks are described as low flow delivery systems. Unlike the non-rebreather and partial rebreather masks, the simple face mask lacks a reservoir bag.
Oxygen can be delivered via nasal cannula, face mask, or endotracheal intubation at normal atmospheric pressure, or in a hyperbaric chamber. It can also be given through bypassing the airway, such as in ECMO therapy. Oxygen is required for normal cellular metabolism.
The traditional low flow system used for medical gas delivery is the Nasal cannula which is limited to the delivery of 1–6 L/min of oxygen or up to 15 L/min in certain types. This is because even with quiet breathing, the inspiratory flow rate at the nares of an adult usually exceeds 30 L/min.
