Larsen & Toubro Star 55, Operating Manual

Page: 156 / 168

Note
Do not rely on the displayed HR value when pacer
is OFF and pacer pulses are detected as QRS.
Beep source : User selectable beep source from ECG/IBP/
SpO
2
/NIBP
Leads : 3 leads for 3 lead cable.
5 leads for 5 lead cable
QRS Indicator : Beep and flashing heart symbol for every
QRS complex detected.
9. Heart Rate
Range : 20-350 BPM
Accuracy : 2BPM or 2% which ever is greater
HR alarms : Adjustable alarm limits
Min : 20 to 320 BPM.
Max : 50 to 350 BPM
4 seconds delay for HR alarms
Time between the silencing of the alarm
and activation is 14 seconds.
Heart rate meter response time: Change from 80 to 120 BPM (6 to 7 sec).
Change from 80 to 40 BPM (11 to 12 sec).
Pacemaker pulse rejection/ : When pacer is ON the monitor will display
detection capability the HR for all single and double pacemaker
pulses either 150 or 250 msec apart with a
pulse width of 0.1 to 2msec and amplitudes
±2 mV to ±500 mV without overshoot.
Lower threshold of slew rate for detection of
pacer pulse is 2.2 V/s.
10. Respiration: (When source is from ECG)
Input : From ECG cable ( RA - LA / RA - LL)
Leakage current : <10

A at 240V AC, 50Hz
Excitation current : < 300
µ
A at 50 kHz.
Sensitivity (max) : 0.2 Ohms/cm
Sensitivity (min) : 4 Ohms/cm.
Range : 0 -150 breaths\min.
