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.
Positive pressure is a pressure within a system that is greater than the environment that surrounds that system. Consequently, if there is any leak from the positively pressured system, it will egress into the surrounding environment. This is in contrast to a negative pressure room, where air is sucked in.

The therapy is an alternative to positive end-expiratory pressure (PEEP). Both modalities stent open the alveoli in the lungs and thus recruit more of the lung surface area for ventilation. However, while PEEP refers to devices that impose positive pressure only at the end of the exhalation , CPAP devices apply continuous positive airway ...
Bilevel positive airway pressure (BPAP) is a mode used during non-invasive ventilation (NIV). First used in 1988 by Professor Benzer in Austria, [10] it delivers a preset inspiratory positive airway pressure (IPAP) and expiratory positive airway pressure (EPAP). BPAP can be described as a Continuous Positive Airway Pressure system with a time ...
The operating pressure inside a typical isolation chamber is set only marginally above local pressure; typically only 0.05 kilopascals (about 0.007 pounds per square inch) above local atmospheric pressure. This is low enough to be undetectable to operators working inside the enclosure (a person sitting in a bathtub full of water is exposed to ...
The ventilator pushes warm, moist air (or air with increased oxygen) to the patient. Exhaled air flows away from the patient. In its simplest form, a modern positive pressure ventilator, consists of a compressible air reservoir or turbine, air and oxygen supplies, a set of valves and tubes, and a disposable or reusable "patient circuit". The ...
Mechanical ventilation utilizes several separate systems for ventilation, referred to as the mode. Modes come in many different delivery concepts, but all conventional positive pressure ventilators modes fall into one of two categories:volume-cycled or pressure-cycled.
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 ...
