What would have happened if the medic didn't notice and the patient died? Would you have got the blame for ignoring it, or management for creating a situation where you had no choice but to ignore some alarms because of false positives, or the manufacturer, or would it have been swept under the rug as "the patient was having heart failure and unfortunately even our state-of-the-art medical care couldn't save him"?
All of those sound superficially plausible to me, although I have my ideas on which are more likely... Would you even do an, um, incident post mortem for something like that or would it just be a statistic?
