Holy...NO!

Last week I had to aspirate a female patient.
So I prepared my aspirator, put on sterile gloves, took the sterile catheter and gently put it in her mouth and removed a lot of disgusting yellow slime that covered the inside of her cheeks.
Felt a certain kind of nausea rise up.
Then I put it a little bit deeper, to get to the slime out which was in her throat.
Suddenly she started coughing and I swear.. she spat out like a whole cup of mucus.
Felt the sudden urge to vomit, gasping: "NO! Holy shit, no!"

Blood, sweat, urine, feces, even vomit for fuck's sake, I don't mind.
But slime.. Yuck..
