Alarm output
Alarm delay time from the monitor to
remote equipment
The alarm delay time from the monitor to remote equipment is ≤2 seconds,
measured at the monitor signal output connector.
Alarm signal sound pressure level range
45 db(A) to 85 db(A) within a range of one meter
Trends
A minimum of 120 hours’ trend data with the resolution no less than 1 minute.
Events
1000 events, including parameter alarms, arrhythmia events, technical alarms,
and so on
NIBP measurements

Full-disclosure waveforms
48 hours at maximum. The specific storage time depends on the waveforms
stored and the number of stored waveforms.
OxyCRG view
48 hours. Trend data is stored one dot per second and the waveform stored is
a compressed waveform.
