Last Monday I went in for a very simple procedure, was planning to be home by lunch time and back at work on Tuesday. It seems as though during my simple procedure I aspirated which caused my lungs to leak fluid. This put me in ICU for 3 days. multiple chest x rays, chest cat scans, heart test and so on. the day of the surgery my blood gas was 65% and 4 days later it was 93%. I think I technically have pneumonia??? My questions~ anyone else have this same experience?, what is the recovery time?, how long should I plan off from work?
