Definition 3.2 – ALARM CONDITION DELAY

ü Filtering in the algorithm that is monitoring for an ALARM CONDITION often causes ALARM CONDITION DELAY. For instance, a heart rate monitor can average the R-R interval for several heartbeats. An abrupt change in R-R interval will not immediately cause a heart rate ALARM CONDITION because it will take several consecutive heartbeats for the calculated heart rate to exceed the ALARM LIMIT. Similarly, a median filter will cause an ALARM CONDITION DELAY. See also the rationale for Subclause 6.10.
