If there is a change in the mechanical properties of the lung/thorax and patient effort, the delivered tidal volume will be affected. The user must then regulate the pressure support level to obtain desired ventilation. [19] [20] Pressure support improves oxygenation, [21] ventilation and decreases work of breathing. Also see adaptive 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.
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.
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.
Mechanical ventilation is often a life-saving intervention, but carries potential complications. A common complication of positive pressure ventilation stemming directly from the ventilator settings include volutrauma and barotrauma. [11] [12] Others include pneumothorax, subcutaneous emphysema, pneumomediastinum, and pneumoperitoneum.
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 pressure throughout the breathing cycle. Thus, the ventilator does not cycle ...
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.
