respiratory therapist should initiate - CORRECT ANSWER: a heated humidifier and
oxygen therapy.
A 33 year-old patient with trauma has been ventilated at the current settings for 24 hours. While reviewing ventilator data from the patient, the respiratory therapist notes
the following:
0800 Peak Inspiratory Pressure (cm H2O) *28* Plateau Pressure (cm H2O) *23* 1000 Peak Inspiratory Pressure (cm H2O) *35* Plateau Pressure (cm H2O) *25* 1200 Peak Inspiratory Pressure (cm H2O) *50* Plateau Pressure (cm H2O) *25*

should - CORRECT ANSWER: replace the tracheostomy tube.
