Yesterday I had a minor procedure involving anesthetic and being "on the table". As the blood pressure cuff inflated, it occurred to me that on medical TV shows, where they are doing far more significant surgeries, the doctors are depicted as having instant and constant measures of the patient's blood pressure. They yell out numbers as the pressure falls and generally do the "we're losing him!" thing.
But my cuff only inflated every few minutes, and took probably at least a minute to get even one reading, what with the inflating and the slow deflating, same as the old days when a person did that.
I did find a few articles describing tech that can read bp continuously, eg Invasive (intra-arterial) blood pressure (IBP) monitoring but I can't tell whether it's normal to use that for anything and everything or only for some patients.
So, are the TV shows making up tech for drama reasons, or is it common to measure blood pressure continuously for big surgeries?
