Dr. Cox: Well, ladies and germs, I'm telling you if you get this shorthand down, it has a way of making your day go just a little bit quicker. "CTD" being "circling the drain." Your patient is on the way out. "SOB", "shortness of breath" and "WNL", "within normal limits". Elvis, you go ahead and feel free to write this down, any time before you leave the building.
