. patient alarms patient alarms are red and yellow alarms. a red alarm indicates a high priority patient alarm such as a potentially life threatening situation ( for example, asystole ). a yellow alarm indicates a lower priority patient alarm ( for example, a respiration alarm limit violation ). additionally there are short yellow alarms, most of which are specific to arrhythmia - related patient conditions ( for example, ventricular bigeminy ). inops inops are technical alarms, they indicate that the monitor cannot measure or detect alarm conditions reliably. if an inop interrupts monitoring and alarm detection ( for example, leads off ), the monitor places a question mark in place of the measurement numeric and an audible indicator tone will be sounded. inops without this audible indicator indicate that there may be a problem with the reliability of the data, but that monitoring is not interrupted. most inops are light blue, however there are a small number of inops which are always yellow or red to indicate a severity corresponding to red and yellow alarms. the following inops can also be configured as red or yellow inops to provide a severity indication : cg leads off • nbp cuff overpress • • cuff not deflated occlusion • • < press label > no pulse • tele disconnected • battery empty / replace battery • all monitors in a unit should have the same severity configured for these inops. 59 3 alarms larm delaythere is a delay between a physiological event at the measurement site and the corresponding alarm indication at the monitor. this delay has two components : the general measurement delay time is the time between the occurrence of the physiological event and when this event is represented by the displayed numerical values. this delay depends on the algorithmic processing and, for certain measurements ( spo2, eeg and bis ), on the configured averaging time. the longer the averaging @topic:8
