Has Anyone Gone Through Intubation for Their Asthma?

Question

I am a sixteen year old asthma patient and had my second severe attack in the last year of October. It got so worse that I had to be admitted in the Pediatric intensive care unit. My doctors were treating me strongly, but my attack was taking its toll on me and I was getting exhausted. My doctor wanted to intubate me, but he was reluctant to do so because of the risks involved. I just could not understand what he was implying by the word risks. I would like to know what would be the points to be able to have consent for intubations for asthma victims of my age. I would like to know whether there is anyone out there who has experienced the same condition and has undergone intubations. Is it as bad as they make out and is it true that you are put to sleep the whole time? If you are intubated and your lungs sound clear when the tube is inserted inside, what is the next course of action? I would be extremely grateful if someone could shed some light on all these queries and give me some answers as soon as possible.
