I've been itching for a few threads to comment on the "obs recording" on the child with an allergic reaction to a snickers sweet.
My understanding is that Dr U had gone into the resuss area to clerk the child. Clerking refers to an assessment done by (usually junior) Drs, most often as part of patient's admission process. It is a systematic process, considering a patients medical, family and social history, past medical problems, medicines prescribed etc etc. the Dr would also physically examine the patient to consider any issues with major organs and bodily processes. Clerking is usually completed once the patient is stable, even if they need admitting and ongoing monitoring.
Observations usually refer to temperature, pulse, respirations and blood pressure. P, R and BP would not usually be recorded during active CPR due to the absence of breathing & circulation, although temp may be if the pt is hypothermic.
If the child needed clerking and was ready to have their obs checked, they may have been being treated in the area known as resuss, but they were not being resuscitated. In my view It is preposterous to suggest that there was a patient safety concern. But it sounds very much like a Dr didn't like being told what to do by a nurse/woman problem.
