Incorrect Blood Pressure

Abstract

With fast highways and gloomy intersections behind us, we enter into the world of hospitals and operating rooms. The story here is about a medical device, a blood-pressure machine. These machines are very reliable and are used in wards and operating rooms. Nevertheless, the overall reliability of a system depends not just on whether the internal components work well. Reliability, as a design and evaluation criterion, should be extended to include correct interfaces and suitable user interaction.

Limbo: In some Christian theologies, the eternal abode or state, neither heaven nor hell.

1. any intermediate, indeterminate state or condition.

2. a place of confinement, neglect, or oblivion.
