ST segment analysis
Measured and displayed simultaneously for up
to three ECG leads
Pulse rate range accepted: 30 to 250 bpm
Cuff pressure measurement range:
ST level range: –6 to +6 mm (–0.6 to +0.6 mV)
NOTE: SpO2 measurement accuracy is based
on deep hypoxia studies using Datex-Ohmeda
Sat Sensors on volunteers. Arterial blood
samples were analyzed by a Radiometer OSM
CO-oximeter. Refer to the sensor instructions
for specific SpO2 accuracy data.
-15 to +350 mmHg
QRS minimum detection level:
NOTE: The cuff pressure measurement range is
equal with cuff nominal and cuff indication
ranges.
Minimum level 0.5 mV with duration between
40 and 120 ms fulfils ANSI/AAMI EC13
standard.
Typical measuring time:
Adult 23 seconds
Infant 20 seconds
Display resolution: 0.1 mm (0.01 mV)
Averaging: calculated from 16 QRS complexes
Pulse rate
Display update interval: 5 seconds
Measurement range: 30 to 250 bpm
Auxiliary ECG output:
Invasive Blood Pressure
Measurement accuracy: ± 5% or ± 5 bpm
Default alarm limits**
Bandwidth of auxiliary output: 0.5 to 40Hz
Measurement range: –40 to 320 mmHg
SpO2: high Off, low 90%
Measurement accuracy: ± 5% or ± 2 mmHg
Gain: 1 mV ECG signal is 1 V at the auxiliary output.
Pulse rate: high 160, low 40
Transducer sensitivity:
5 µV/V/mmHg, 5 VDC, maximum 20 mA
Propagation delay: < 15 ms
Limits are adjustable.***
Pulse rate
Measurement range: 30 to 250 bpm
Accuracy: ± 5% or ± 5 bpm
Sensor emitter wavelength ranges
The pacemaker pulses are absent but may cause
interference at the auxiliary ECG output.
Red LED: 660 nm
Infrared LED: 900 nm
An auxiliary device that fulfils the requirements of the IEC
60601-1 standard can be connected to the auxiliary
output. There are no other limitations, because the
auxiliary output of the monitor is galvanically isolated from
patient applied part of the ECG measurement.
