When checking gag on my intubated patients I usually just move the ETT tube a bit if they don't cough with suction. The other day I saw a nurse shoving the ETT down so far I thought I'd lose sight of it! I also saw her later trying to illicit gag by using the yankeur and it too was halfway down the patients throat! When I approached her she got really defensive about it. I tried to tell her nicely that it only takes minimal stim to determine gag, and boy was she mad. I guess if you shove it far enough down and tickle their anus they'll eventually respond, huh?
