During inspiration, the inspiratory positive airway pressure, or IPAP, forces air into the lungs—thus less work is required from the respiratory muscles. The bronchioles and alveoli are prevented from collapsing at the end of expiration. If these small airways and alveoli are allowed to collapse, significant pressures are required to re ...
Nasal expiratory positive airway pressure (Nasal EPAP) is a treatment for obstructive sleep apnea (OSA) and snoring. [ 1 ] [ 2 ] Contemporary EPAP devices have two small valves that allow air to be drawn in through each nostril, but not exhaled; the valves are held in place by adhesive tabs on the outside of the nose.

Treatment for central sleep apnea differs in that the device is set not at one constant optimal pressure but rather at two different settings, one for inhalation (IPAP) and for exhalation (EPAP), maintaining normal breathing rhythm by inflating the patient's lungs at regular intervals whose specifics, such as the breathing rate and the duration ...
Nasal EPAP, which is a bandage-like device placed over the nostrils that utilizes a person's own breathing to create positive airway pressure to prevent obstructed breathing. [121] Automatic positive airway pressure, also known as "Auto CPAP", incorporates pressure sensors and monitors the person's breathing. [122] [123]
Modes of mechanical ventilation are one of the most important aspects of the usage of mechanical ventilation.The mode refers to the method of inspiratory support. In general, mode selection is based on clinician familiarity and institutional preferences, since there is a paucity of evidence indicating that the mode affects clinical outcome.
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.
Positive end-expiratory pressure (PEEP) is the pressure in the lungs (alveolar pressure) above atmospheric pressure (the pressure outside of the body) that exists at the end of expiration. [1]
Peak inspiratory pressure (P IP) is the highest level of pressure applied to the lungs during inhalation. [1] In mechanical ventilation the number reflects a positive pressure in centimeters of water pressure (cm H 2 O).
