I try to teach my residents to measure blood rpessures every 2.5 minutes during operations and even 1 minutely during critical times (induction, blood loss etc).

And then I try to teach them to accurately record every reading on paper. I find than most of them will give a very "romanticised" version of events. The records are invariably more smooth than the actual course of events.

Then we switched to automatic printouts and the machines recorded every nuance (including artefacts, of course). The result was that my residents no longer looked at the readings on the monitor, confident that they could simply press PRINT at the end of the case.

Good old-fashioned clinical acumen is a dying art I fear. ::)
