Re: Neither should you expect people who have spent their entire career...
Aircraft pilots are one of the few professions that actually learn, train and regularly practice a wide range of emergency scenarios. And are actually given resources (a copilot, redundant systems) by the beancounters so they can cope in many different emergencies. And even then they sometimes get it wrong.
If you want a hospital to cope in a "no computers" scenario, then everyone has to train and practice for that scenario. And the beancounters have to have enough staff available. E.g. a nurse who's doing routine checks on a patient can still respond to an automated alarm on another patient. But without the automated alarms, you may need enough nurses to assign one to each patient that is in a private room, and one for each area of the ward, so they can monitor the patients, as well as having other nurses for the routine stuff. There simply won't be enough nurses on duty for that.
