HI, I was in the same boat a few years ago with my dad, he was having his knees replaced and died on the operating table, he had a stroke and they brought him back but was in a coma, I waited 2 days and I just felt he was waiting for me, so we drove 2.5 hours and caught a plane from wa to qld, I was in intensive care with him, and I stroke his head and said Dad I am here now, and a tear ran down from the side of his eye, when he finally came out of the coma a few days later, I said "dad do you remember me talking to you" and he said "how could I forget a face that launched a thousand ships", I will never forget that, he is still alive but not for long, bloody asbestos and bowel cancer, but I will always remember that day,so you will know inside what you need to do, take care.
