There is a lot of good information in the article about ways to avoid a recurrence. After exhausting all the doctors who treated me during my hospitalization and those recommended by Dan, one cardiologist, 2 pulmonary doctors and an endocrinologist, the only thing they could find wrong after extensive testing was an elevated thyroid caused by a doctor treating me for a condition that did not exist. I am not overweight nor do I have any heart or lung conditions. Believe me, they tested me for everything. Under the instruction of the endocrinologist, I got off of Armor thyroid medicine and my levels returned to normal before I once again began to start diving.
I had a choice to make. Since the doctors could find no reason for the occurrence, they also could not give me any reason not to dive again.
I made the decision that I would step up my cardio and weight training, get regular checkups from my local doctor, and listen to my body and my mind before, during and after every dive. In other words, bring my "A game". I also carry an AL40 stage bottle now with 100% o2 with a portable cpap by Rescuean with me every time I dive. Unless I am using it for deco, it is equipped and ready to go on the surface.
Two weeks ago I descended to 94 ft deep approximately 500 ft back in a cave where my IPE occurred last July 4th. Believe me, I was listening. I had been working up to this for months. I started back diving after 3 months of doctor visits and tests and then one more round of tests from an Internal Medicine doctor two weeks before my first dive to tell me everything was normal. I started with beach dives, spring dives and then worked my way back to cavern dives. The dives I did the last two weeks would be considered intro cave dives. My two buddies are intro and I was following the rules that applied to their 1/6's. The first couple of dives we stopped there, in the place where I first started coughing and turned the dive. Then the next couple of dives we penetrated another 500 ft past this.
This was quite a confidence booster but I will never forget what happened or how it felt to swim that 300ft on the gold line plus another 200ft in the cavern to get back to the entrance so that I could ascend, coughing every breath and my lungs filling with fluid, from the inside.
