physiological abnormalities in the anaesthetised patinet unergoing a
surgical procedure and what appropriate action should I take (care in
anaesthetic practice)

Are you an anesthesiologist's assistant or an esthetician's assistant?
 Do you help apply makeup or do you help during surgery?  Could you
restate and clarify what you are asking?  Could you give examples of
what you are looking for?

bigblue, although flakypastry's question contains misspellings, it
does mention ..."anaesthetised patinet unergoing a surgical
procedure..."

flakypastry,
I can tell you that if it was me undergoing surgery and ANYTHING
abnormal was noticed by an assistant to the anesthesiologist, I would
expect him/her to immediately get the qualified and licensed
anesthesiologist in the room, STAT.
