From admission till 05/02 he required to have intermittent oxygen requirements and was volume up (visible on daily chest x-ray) as result nephrology continued aggressive peritoneal dialysis until 05/02. Nephrology ultimately recommended transition to hemodialysis on 6/4/22. During this hospitalization, patient developed hypotension secondary to hypovolemia leading to ischemia (in the setting of low-flow state, however echocardiogram limited performed with gradient within normal range) he received 1.5 L of fluid resuscitation, and his midodrine of 20 mg 3 times a day was continued. He was then optimized for BKA and underwent on 05/03 by vascular surgery.
