Right in front of my eyes. Thank goodness I had my charge nurse there and a tech. I don't know if I would have realized he was going downhill so fast. The other nurse knew that the RAP team need to be called, then maybe two minutes after the RAP team got in the room I called a code. Once the patient was stabilized he was transferred to the unit. I believe he will be fine. Some of my patients are so sick from the time I get them from another nurse. Their vitals can be poor even from the time I get them. Looking back through the day, they look the same. Experienced nurses say it will come with time, that you can just tell by looking at them with experience. Any tips from experienced nurse how you "just know"?
