Question 22

The RT performs a patient-ventilator system check on a 24-year-old,5-foot,10-inch male patient who has been intubated because of a drug overdose.The RT notices what appears to be swelling around the patient's upper anterior chest and neck area.Palpation elicits a tissue paper feeling.The ventilator settings are: VC-CMV,rate 12/min with no patient assist,Vᴛ 900 mL,PEEP 5 cm H₂O,FɪO₂ 0.4,Tɪ 1.2 sec.The most appropriate action for the RT to take is which of the following?

(Multiple Choice)

4.8/5
