The following are variables that causes a breath to begin during mechanical ventilation: I. Negative pressure II. Flow III. Time IV. Pressure Limit 

A patient is currently on CMV with the following ventilator settings and ventilator waveform: AC/VC Rate – 14 breaths/min Set VT – 450 ml PEEP – +10 cm H2O FIO2 – 0.50     What should the respiratory care practitioner suspect?

An 18-year-old patient who is having a severe asthmatic episode is being mechanically ventilated. The pressure limit alarm is sounding frequently. The patient is very agitated and his respiratory rate is 36 bpm. Bilateral breath sounds with minimal wheezing are noted. Which of the following should the respiratory therapist recommend?
