hello, hello!!!!!!!!!!!!How does the deep vein thrombosis prophylaxis help with VAP prevention? Is it also used as a prophylactic for people at risk for pneumonia, who aren't on vents? Is the rationale behind a Peptic Ulcer Prophylaxis because of the possibility of regurgitating gastric acid into the trachea? Is there any evidence that one agent is better than the other? I could not find info on this.The ETT is inserted into the mouth, then down the trach and a balloon hold it in place? How long do patients typically keep this in for?A tracheotomy is a procedure performed in surgery for long-term trach patients?
