You are caring for a 25 year old male post op for a lap choly. His estimated IBW is 72 kgs. He has diminished breath sounds bilaterally. His RR is 26, VC 480 ml, VT 290. His nurse comments that the patient is a “slug” who will not do his IS despite repeated reminders. Based on this data, what would you recommend?
