Mouth to mouth resuscitation symptoms and conditions

A few years ago, my doctor prescribed advair to better control my asthma. After a few days, I had an almost fatal reaction to the medication. I woke up feeling fine, took a shower, and got ready for work. I took a puff from the advair discus and immediately felt my throat closing. I started gasping for air and took my rescue inhaler which didn't work at all. The nebulizer didn't work either. Within minutes I collapsed and became unconscious.Luckily, my son was late for work that day so he called 911 and gave me mouth to mouth resuscitation until the paramedics arrived. My blood pressure dropped to 60/30 and I had to be intubated for the first time. I remained unconscious until I reached the hospital. The doctor said the only reason I survived was because my son saved me. If I had been alone that day I'm sure everyone would have assumed that I died from an asthma attack. I wonder how many other people that happened to. Since then, I have been very careful about taking new medications.
