But are you saying that you want to suck people's noses?

To answer your question, the nasotracheal part describes the pathway. You pass a suction catheter through the nose and down the trachea to facilitate suctioning of the trachea and larger airways of the lungs. This path is used because the natural curve of the nasal airway tends to guide the catheter straight toward the trachea. If you try to go through the mouth, the catheter almost always ends up unwantedly in the esophagus instead.
It's a fairly unpleasant experience that's rarely performed on someone who is alert and oriented. Think about how sensitive your cough reflex is. Just a little water going down the wrong pipe can set off a pretty nasty coughing fit, right? Now imagine someone intentionally jabbing around in there with a hard plastic catheter that they just crammed down your nose for up to 30 seconds at a time, while also applying suction that quite literally sucks the air right out of your lungs.
However, I have met quite a few people who didn't mind it much, if at all, and have even ran into a few hardcore people who will perform it on themselves.
