How common is this scenario. This happened to me last thanksgiving day:
Let me first state that I do not do drugs at all, so it's impossible this was due to inhaling something due to drug use...
Day before thanksgiving: Trouble breathing, had to leave the window open for colder air to make it easier for me to breathe
Thankgiving day: Trouble breathing, rapid breathing, caughing up mucus
Thanksgiving night: My gf (now fiancee, who's an RN) brought me to the ER at the hospital she used to work at. They put me on oxygen, which helped but my blood-oxygen levels were still low. The ER doctor decided that there might be something wrong with me at this point and decided to keep me. The nurse wanted to send me home on antibioltics saying it was just a pneumonia, but the doctor insisted to keep me insisting something was wrong with me, HE SAVED ME LIFE by keeping me inpatient. I would've died at home!
Thanksgiving night around 10pm: Admitted inpatient to the intermediary ICU, blood gas blood tests came back bad. They intubated me.
Midnight: Inpatient @ ICU, sedated on a vent
2 days later: Lung biopsy sent to Mayo in AZ which came back with higher than normal white eocynaphilic (sp?) white blood cells but they could not find anything wrong. Possible cause was that I inhaled something which caused this but they were not sure.
At this point I was on medical leave from work, I'll leave out all of those details as they are not relevant.
Days to follow - approx 20 days I was in a sedated state at the ICU with breathing difficulty on a vent. They had me on IV antibitics, fentanyl drip, propophol, and morphine shots which caused me to get jaundice along with the other drugs they had me on. They put two pick lines in me, one was a special one going straight to the heart for the blood gas levels I believe? They also drained fluid from both of my lungs and installed a G-Tube for feeding as I lost 40 lbs at the point (down from 230 to 190lbs). They also put me in a roto-prone bed which rotated to help with the fluid in my lungs.
Around mid December I started to get better, but not enough. My gf, the nurse, insisted they cut for a trach in my neck because the tubes might cause vocal cord damage, so they cut for the trach.
Days later I was concious but I do not remember anything from Thanksgiving night intitially at the ER on. I'm assuming that's because my body was in shock. I don't even remember giving them the OK to intubate me.
Eventually I was out of the ICU by Christmas of '10. I started to walk which was hard due to all the muscle degredation from laying in bed. My insurance denied physical rehab, but they eventually gave in. I was sent to a nursing home which I clearly remember was being one of the worst experiences as I was totally with it at that point. They had me in quarantine as one of my bacteria results came back positive which was resistant to antibiotics. This eventually turned out to be as a false positive... so I was in quarantine throughout all of this and everyone who came to visit me had to wear full gear including masks and gloves.
They sent me back to the hospital after being at the nurse home for 2 days (laugh), where I finished physical rehab.
Total time out of work was 2 days short of 3 months, total ICU time was over a month...
Still no root cause... which baffles my mind. All I'm left with is knowing I have a fiancee now who will stick with me if I'm dying

, and tons of scars...
