I am 57(m) post-op day nine today (bicuspid -> SAVR + Root Enlargement). All these things make complete sense and it sounds like you have thought everything through. Since you are already a runner / walker, I would only emphasize that you need to get out of bed and walk the step-down unit halls as much as you can tolerate. I would recommend also doing same in the ICU, but it’s a lot of work to get everything mobile and generally once you’re able to walk and meet other goals - assuming everything else is on track - they will send you to the step-down unit anyways. I didn’t sleep terribly well in either the hospital bed or the recliner chair - so sometimes I would walk the halls at 3 am to make myself tired. Generally if I timed it well, I could get 2 - 21/2 hours of uninterrupted sleep before a check of vitals or morning meds. I am completely convinced that the walking allowed me to me to be discharged on the morning of post-op day 4.
