You are caring for a patient in the ICU admitted with ARDS after exposure to toxic fumes from a hazardous spill at work. The patient has become hypotensive. What is the cause of this complication to the ARDS treatment?
A) Pulmonary hypotension due to decreased cardiac output
B) Severe and progressive pulmonary hypertension
C) Hypovolemia secondary to leakage of fluid into the interstitial spaces
D) Increased cardiac output from high levels of PEEP therapy
Ans: C
Feedback: Systemic hypotension may occur in ARDS as a result of hypovolemia secondary to leakage of fluid into the interstitial spaces and depressed cardiac output from high levels of PEEP therapy. Pulmonary hypertension, not pulmonary hypotension, sometimes is a complication of ARDS, but it is not the cause of the patient becoming hypotensive.
