Proportional assist ventilation

Considerable interest has developed in pressure-assisted methods of ventilatory support. Two of these have been described: pressure support ventilation and the more recent proportional assist ventilation described by Magdy Younes in 1992. These methods assist each spontaneous breath by providing positive pressure at the airway during the period of spontaneous inspiration. During these ventilatory modes, the ventilator-controlled variable is airway pressure, while inspiratory flow and tidal volume are determined by the combined action of the pressure generated by the respiratory muscles (muscular pressure) and the pressure generated by the ventilator (airway pressure). Because the ventilatory consequences of these methods are essentially the result of patient-ventilator interaction, the patient retains considerable control over flow and breathing pattern.
