auto, the monitor will use the heart rate from the ecg measurement as the alarm source whenever the ecg measurement is switched on and at least one ecg lead can be measured without an inop condition. • the monitor will automatically switch to pulse as the alarm source if : a valid ecg lead can no longer be measured - and a pulse source is switched on and available, the monitor then uses the pulse rate from the measurement currently active as system pulse. while pulse is the alarm source, all arrhythmia and ecg hr alarms are switched off. if an ecg lead becomes available again, the monitor automatically uses hr as alarm source. note : if ecg is switched off, the monitor will always change to pulse as alarm source, if a pulse is available. one exception to this rule can arise when you have a telemetry device paired with your monitor. the monitor ecg is then deactivated but the monitor may be configured to allow only ecg as the active alarm source. in this case the monitor will not switch to pulse as alarm source and pulse will not be available as a selection in the ecg / pulse alarms menu. 82 warning selecting pulse as the active alarm source for hr / pulse switches off the arrhythmia alarms listed in the section " ecg and arrhythmia alarm overview " on page 149, including asystole, vfib and vtach alarms, and the heart rate alarms. this is indicated by the message ecg / arrh alarms off ( unless this has been configured off for your monitor ), and the crossed - out alarm symbol beside the ecg heart rate numeric. the message ecg / arrh alarmsoff can be configured off, or to switch to a yellow medium severity ) inop after a fixed number of hours. high and low pulse rate and extreme bradycardia and extreme tachy @topic:8
