Question

Quizplus · Accepted Answer

Pressure support ventilation (PSV) ends inspiration when flow decreases to a preset value, allowing for more natural breathing patterns and improved patient comfort. Intermittent mandatory ventilation (IMV) and continuous mandatory ventilation (CMV) are both modes where the ventilator initiates and terminates breaths according to a set frequency and tidal volume, not based on the patient's respiratory efforts. Airway pressure release ventilation (APRV) is a mode that allows for prolonged inspiratory times and uses two levels of positive airway pressure to improve oxygenation. It does not end inspiration when flow decays to a preset value.
