Reliability, Testability, Alarms, and the Fail-Safe Concept
Reliability and testability of equipment used in anesthesia, alarm technology, and the fail-safe concept can be discussed from the perspective of the investigator or as experienced by the clinician in 1994. In this presentation I will present the view of the North American clinician working with modern and well-established equipment rather than with experimental or advanced research systems. Therefore, I shall focus on current systems in terms of their reliability; I shall mention testing practices, delineate alarms, and examine how far we have come to realize fail-safety. Finally, I shall address conceptual issues surrounding the question of reliability, testability, alarm technology, and the fail-safe system.
