I don't know about other hospitals, but where I work a ventilator is an indication for bronchodilator. It matters not if the patient has bronchospasm or not, because just being on a ventilator is indication enough.
So, today, when the third overdose patient in as many hours was put on a ventilator by your humble RT, and this patient too was ordered up on Ventolin Q6 hours, your humble RT approached the nursing supervisor with the quote of the day:
"Hey, Amanda, I was wondering if you'd fetch me -- at your convenience of course-- a Ventolin inhaler for this man's imaginary bronchospasms and imaginary wheezes."
Imaginary wheezes, bronchospasm, asthma, COPD and pneumonia seem to be on the prowl of late, so be on the lookout!!!
