when a patient coughs, or when we make them cough during suctioning, it makes the seal where the cuff is located not be a seal any longer, this is why the vent alarms when your patient is coughing--well the change in pressure and/or volumes. secretions sometimes get coughed into the mouth as well.so no, you are not entirely correct by saying they cannot aspirate. a lot of folks have swallowing difficulties and have no reflexive gag if they aspirate fluid into the lungs. the cuff is not 100% airtight and patients cough/made to cough many times a day. not all secretions and/or fluid can be suctioned off of the cuff with the VAC or suctioning to the back of the throat either. as well, you need swallowing to make sure that any trickling fluids go down the esophagus rather than to the lungs which is something you cannot guarantee as for the aforementioned. its pretty difficult to swallow with an ETT in your mouth, as well if your mouth is dry, and sedation/analgesics.with that, i say no to ice and venting. i say no to any npo status unless specifically ordered. i introduce all fluids if ordered them from npo from very thick and work my way to thin. apriration only leads to longer stays. if we dont prevent it, ppl will always just think ice is ok.and ice melts the second the temperature is not freezing, so it melts pretty much instataneously in the mouth. and it is much different than giving mouthcare! i dont know about what others do, but i squeeze out swabs before i give them to prevent dripping of water, and if i brush teeth, i use the yaunker int he back of the thraot to prevent it rolling to the back of the mouth!
