A female patient who is 5'7" tall and weighs 68 kg is being mechanically ventilated with vol-ume-controlled continuous mandatory ventilation (VC-CMV), set rate 12,
patient trigger rate 25 breaths/min, tidal volume (VT) 500 mL, set flow rate 60 L/min, fractional inspired oxygen (FIO2) 40%, positive end-expiratory pressure (PEEP) 5 cm H2O. The patient is currently in distress using accessory muscles of inspiration. The respiratory therapist performs a patient-ventilator system check. The flow-time waveform shows a failure of the expiratory flow to return to zero before the next breath is triggered. The most appropriate action for the respira-tory therapist to take includes which of the following? a. Sedate the patient. b. Switch to pressure-controlled continuous mandatory ventilation (PC-CMV). c. Decrease set rate to 8 breaths/min. d. Switch to volume-controlled intermittent mandatory ventilation (VC-IMV).
