I had my own bad experience when I died two days after open heart surgery in the intensive care ward when they rolled my over in bed to do an x-ray and I threw a pulmonary embolus.
I stopped breathing and my heart arrested. They had to cut me back open and unwire my breast bone so the surgeon could hand-massage my heart back to beating again in normal sinus rhythm. Took him 8 minutes before the heart started beating on its own. He told my later, that he would have given up after 10.
I was a mess. Instead of a planned 5 days in the hospital after a quadruple bypass and valve repair, I was laid up in intensive care for 5 weeks. Two blood transfusions. My legs were like jelly when I was finally discharged. I could hardly breath. It took me over two years to come back so that I am pretty fit again.
At 71 years of age, I am lucky to be alive and count my blessings everyday that I survived that near death experience.
Good luck to you and prayers for a full and speedy recovery.
Thank you, and God Bless You.
