Mr. Franklin, a 75 kg patient with ARDS, is being mechanically ventilated in VC-SIMV rate 12 and VT 600 mL. Over a period of 8 hours, the peak inspiratory and plateau pressures have increased to 66 and 45 mmHg, respectively. The attending physician asks the therapist to suggest changes to minimize the effects of rising airway pressures. The therapist should recommend initiation of

A patient is receiving bilevel noninvasive therapy at the following settings: IPAP 15 cmH2O, EPAP 5 cmH2O, FiO2 0.50. Recent arterial blood gas results reveal hypoxemia. To compensate, the respiratory therapist increases the EPAP setting to 8 cmH2O. What other change should be made to ensure a consistent level of ventilatory support is maintained during spontaneous breaths?

Which of the following is a condition that could trigger the high-pressure alarm?

A 75 kg (165-lb) male is being mechanically ventilated in the volume-control mode at the following settings: Tidal volume 550 mL, Rate 10, FiO2 0.30, PEEP 5 cmH2O Arterial blood gases reveal the following: pH 7.41, PaCO2 39 torr, PaO2 49 torr, HCO3 24 mEq/L Which of the following should the therapist recommend be increased?

What are the two ventilator parameters that can be adjusted to maintain the optimum minute ventilation?

The fundamental dimensions are length, mass and time.
