Dual-control modes of ventilation are auto-regulated pressure-controlled modes of mechanical ventilation with a user-selected tidal volume target. The ventilator adjusts the pressure limit of the next breath as necessary according to the previous breath's measured exhaled tidal volume.
Airway pressure release ventilation graph. Airway pressure release ventilation is a time-cycled alternant between two levels of positive airway pressure, with the main time on the high level and a brief expiratory release to facilitate ventilation. [5] Airway pressure release ventilation is usually utilized as a type of inverse ratio ventilation.
Originally developed for use in anaesthesiology, many variants of breathing system are in clinical use, but most comprise a source of fresh gas flow, a length of breathing tubing to direct the gas, an adjustable pressure limiting valve to control pressure within the system and direct waste away, and a reservoir bag to allow assisted ventilation ...
Optimal - e.g. - PC-IMVoi, oi is the tag for Adaptive Support Ventilation (ASV), technically due only to minor safety algorithms, if not it would only be "optimal" but not "intelligent". [5] Dual - e.g. - VC-CMVd is the tag for CMV + pressure limited ventilation. Biovariable - PC-CSVb is the tag for Variable Pressure Support.
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 be referred to as BiVent.
Another type is the intermittent abdominal pressure ventilator that applies pressure externally via an inflated bladder, forcing exhalation, sometimes termed exsufflation. The first such apparatus was the Bragg-Paul Pulsator. [43] [44] The name of one such device, the Pneumobelt made by Puritan Bennett has to a degree become a generic name for ...

The ventilator prevents the accumulation of carbon dioxide so that the lungs don't collapse due to the low pressure. [2] [3] The use of artificial ventilation can be traced back to the seventeenth century. There are three ways of exchanging gases in the body: manual methods, mechanical ventilation, and neurostimulation. [4]
