Nasal prongs or a nasal mask is the most common modality of treatment. [13] Nasal prongs are placed directly in the person's nostrils. A nasal mask is a small mask that covers the nose. There are also nasal pillow masks which have a cushion at the base of the nostrils, and are considered the least invasive option. [16]
Non-invasive ventilation (NIV) is the use of breathing support administered through a face mask, nasal mask, or a helmet.Air, usually with added oxygen, is given through the mask under positive pressure; generally the amount of pressure is alternated depending on whether someone is breathing in or out.
A breathing mask, also called a facepiece, is a component which covers the mouth and nose, sometimes also the eyes and other parts of the face, and may seal against the face. A breathing mask is usually effective, allows mouth and nose breathing, and can usually be sealed adequately without effort by the user.
Elastomeric masks must be individually fit-tested and inspected for full efficacy. [2] They may be somewhat easier to fit than filtering facepiece respirators. Older mask designs were designed only to fit young adult men of average weight and a narrow range of ethnicities; newer ones use updated anthropometry and fit more people. [5]
An open circuit SCBA typically has three main components: a high-pressure gas storage cylinder, (e.g., 2,216 to 5,500 psi (15,280 to 37,920 kPa), about 150 to 374 atmospheres), a pressure regulator, and a respiratory interface, which may be a mouthpiece, half mask or full-face mask, assembled and mounted on a framed carrying harness.
