I have had it several times, they always try that before I have been intubated, I have been intubated more times then you can count on two hands...
I do feel hot from it but when it works, it works great, sometimes it does, sometimes it doesn't.... I have declined slightly tonight and most likely will go in for it, I am hoping to wait till the morning....since everyone at my house is already in bed!!!
Thanks for the warning...
