By request, some ICU topics. This mode of ventilation is occasionally used in medical, surgical, or trauma patients with acute respiratory distress syndrome. The advantage is that it allows the patient to be awake or lightly sedated, spontaneously ventilating. Its high mean airway pressures aid alveolar recruitment.
Challenge: What kind of mode is this?

this is the type of ventilation with lower frequency and prolonged positive airway pressure to maximize exchange time. it is described as a more protective and still efficient method for ARDS patients ( plateau pressure ventilation i think)
yes - no definite benefit in large randomized trials, but we sometimes use it as a rescue strategy in refractory ARDS

Ventilators I
This is airway pressure release ventilation (APRV), an inverse ratio pressure control mode. The patient spends the majority of time at a high airway pressure (Phigh for Thigh) and can spontaneously ventilate at that pressure. To allow ventilation, the mode drops the patient very briefly to a low airway pressure (Plow for Tlow).
