PY - 2018 T2 - Reichman's Emergency Medicine Procedures, 3e AB - The term noninvasive ventilation (NIV) refers to delivering positive-pressure ventilation through an interface (i.e., face mask, nasal mask, or nasal plugs) rather than intubating the trachea.1,2 It may be used to prevent acute respiratory failure (ARF) as a prophylactic treatment, to treat ARF, or as a curative treatment to avoid reintubation.3,4 There are different types or modes of NIV. The most frequently used are continuous positive airway pressure (CPAP) and bilevel positive airway pressure (BIPAP). CPAP is a method to deliver constant positive airway pressure during the inspiratory and expiratory phase of breathing.5 BIPAP refers to the association of two positive airway pressures (i.e., pressure support ventilation [PSV] during inspiration and lesser pressure value during expiration).5 The pressure applied during expiration is commonly incorrectly referred to as positive end expiratory pressure (PEEP). The correct term is expiratory positive airway pressure (EPAP), or the pressure delivered throughout the expiratory phase.
