pressure-support ventilation

pressure-support ventilation (PSV),

mechanical ventilatory assistance in which each breath triggers a pressure-limited amount of support. The ventilator only provides support of each breath to a preset amount of pressure, thus the volume breathed can differ from breath to breath taken.

Many forms of closed-loop, automatically applied partial support protocols have been developed on many different ventilators; I have reviewed and tried all of them, including mandatory minute ventilation (MMV), pressure-support ventilation (PSV), proportional assist ventilation (PAV), SmartCare/PS, AutoMode and NAVA (Neurally Adjusted Ventilatory Assist).
Effects of heat and moisture exchangers on minute ventilation, ventilatory drive, and work of breathing during pressure-support ventilation in acute respiratory failure.
Towards this end intermittent mandatory ventilation (IMV) with CPAP (the latter assisted by pressure-support ventilation (PSV)) worked in some and bilevel positive airway pressure (BIPAP) (again with PSV) gave reasonable results in others.
For their patients with high risk for respiratory distress after extubation, the authors use a form of noninvasive positive pressure ventilation (NIPPV) called noninvasive pressure-support ventilation (NPSV).
The ventilator has dimensions similar to a laptop computer and offers volume-control ventilation, pressure-control ventilation, pressure-support ventilation, flow-triggering, internal oxygen-blending, and low-pressure oxygen supplementation.
(11,23,24) Tassaux and colleagues demonstrated improvement in patient-ventilator interaction and reduction in signs of asynchrony with ASV compared with synchronised intermittent mandatory ventilation (SIMV) and pressure-support ventilation (PS) in patients during early weaning with partial ventilator support.
Baseline values for the hypercapnia test were obtained after applying five minutes of pressure-support ventilation (PSV) with a pressure of 7 cm[H.sub.2]O, without positive end-expiratory pressure, and Fi[O.sub.2] was set at 1.0 to prevent hypoxaemia for patients' security and to avoid hypoxic stimuli.
