alarm is being briefly activated prior to each breath. Which of the following is most likely
the cause?
A. the patient is fighting the ventilator
B. the flow rate is set too fast
C. the alarm delay is set too short
D. the peak pressure limit is set too high: C.

ventilated. An arterial blood gas has been obtained. Ventilatory data andblood gas results

D. Decrease the FIO2 to 0.35: C. Decrease the mechanical deadspace
3. A spontaneously breathing 76-year-old patient who weighs 60 kg (132 lb) ison an FIO2
of 0.45 via a trach collar. He has had a change in his tidal volumefrom 600 mL to 300 mL
and his respiratory rate went from 12 /min to 24 /min.Which of the following changed
