– normally an inspiratory to expiratory time ratio (I/E) of 1:2 is used – inverse I/E is also utilized in ARDS to prevent barotrauma – long sustained inspiration reduces mean airway pressure while increasing the PaO2 for a given FiO2; – despite the benefits in gas exchange, the prolonged inspiratory duration relative to expiration is … Read more
