Positive airway pressure (PAP) is a mode of respiratory ventilation used in the treatment of sleep apnea.PAP ventilation is also commonly used for those who are critically ill in hospital with respiratory failure, in newborn infants (), and for the prevention and treatment of atelectasis in patients with difficulty taking deep breaths.
The application of positive pressure may be intended to prevent upper airway collapse, as occurs in obstructive sleep apnea, or to reduce the work of breathing in conditions such as acute decompensated heart failure. CPAP therapy is highly effective for managing obstructive sleep apnea.
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.
A pressure-time graphic. Airway pressure release ventilation (APRV) is a pressure control mode of mechanical ventilation that utilizes an inverse ratio ventilation strategy. APRV is an applied continuous positive airway pressure (CPAP) that at a set timed interval releases the applied pressure. Depending on the ventilator manufacturer, it may ...
For moderate to severe sleep apnea, the most common treatment is the use of a continuous positive airway pressure (CPAP) or automatic positive airway pressure (APAP) device. [67] [70] These splint the person's airway open during sleep by means of pressurized air. The person typically wears a plastic facial mask, which is connected by a flexible ...
Continuous spontaneous ventilation is any mode of mechanical ventilation where every breath is spontaneous (i.e., patient triggered and patient cycled).. Spontaneous breathing is defined as the movement of gas in and out of the lungs that is produced in response to an individual's respiratory muscles.

Mean airway pressure typically refers to the mean pressure applied during positive-pressure mechanical ventilation. Mean airway pressure correlates with alveolar ventilation, arterial oxygenation, [1] hemodynamic performance, and barotrauma. [2] It can also match the alveolar pressure if there is no difference between inspiratory and expiratory ...
