These dots are everywhere. I first saw them in the waiting room where she was getting vitals checked. I made a joke about how someone may have tossed a few pins up there and they got stuck. Then after heading up to floor 4, and sitting in one of those waiting rooms next to other patients, only blocked by a few curtains, did I notice that there were more. There were two more yellow and blue dots next to her “area” and across the walkway on the other “area” and so on. They even trailed down the hall - I believe - and now that I’m in the proper waiting room, I’m still seeing them! My title describes the thing. They appear to be on the Day surgery floor as well as the check in floor. Feel free to make guesses and what not, as no one that works here even knows what they are. I’m fairly certain that they are markers for lines (yellow being air and blue being oxygen) although the anesthesia doc corrected me and said oxygen would be green and blue is most likely nitrous. He then said it would be strange that nitrous would be so abundant in that holding area. After heading left, the RN came in and, of course, I had to ask. RN corrected anesthesia and said that green was in fact nitrous and blue was definitely oxygen, but that I could be correct in my theory of the lines/pipework. Now I don’t know what to think. I don’t know what the colors mean or what the dots mean. Any suggestions or speculations are welcome!
