You are checking a ventilator and notice that the peak pressure has decreased from 30 to 15 cm H2O and the volume on the exhaled tidal volume display has dropped from 800 to 400 ml. Which of the following may have happened? The patient has become disconnected from the circuit. The exhalation tubing has loosened. The cuff on the endotracheal tube has been deflated or has developed a leak. The temperature probe site is not capped tightly. There is water in the tubing.

A patient is being mechanically ventilated in Pressure assist/control mode, with an FIO2 of 0.6, PEEP of 5, a set rate of 18, and a tidal volume of 650 ml. The patient is breathing 1:1 with the ventilator. Results of an arterial blood gas analysis are below: pH 7.52 PaCO2 27 torr PaO2   70 torr HCO3- 21 mEq/liter Base excess -1 mEq/liter SaO2    93% On the basis of these results, the most appropriate action would be to:
