Middle-aged male ~48 hours post aortic valve replacement. In ICU still due to being on minimal doses of IV clevidipine while home BP meds are being reinitiated/adjusted. Aggressive diuretic doses needed - we figured he was still about 1.5 liters above where we wanted him, so a furosemide drip was just started. History of bicuspid aortic valve and stenosis for which he received an aortic valve replacement. Other pertinent history just hypertension. Operative course insignificant and hemodynamically stable without vasoactive or mechanical support. Extubated a few hours after surgery without complications and currently with a typical oxygen requirement of a couple liters via nasal cannula. O2 sats gradually decreasing from 99-100% to 90-92% at shift change. Currently with mild shortness of breath attributed to having returned to bed just prior to me arriving to room for beside report. Is obviously working to breathe with resp rates in mid-upper 20s and unable to complete sentences. SpO2 continues to gradually decrease despite escalation of oxygen delivery & methods. SpO2 now low 80s. Crackles B/L with decreased air movement on right side. Movement symmetric. Stat chest X-ray and bipap per PA for assumed pulm edema. With bipap, immediate SpO2 97%, resp rate to 20 and visibly more alert. Then, xray arrives and we get image 1. Was bipap a mistake?
