circuit settling time with offset voltage < 500
mV
Noise — < 30 µV p-v, refered to input (rti), at 30
Hz bandwidth
CMRR — > 85 dB (monitor mode)
QRS Detection — Detects QRS complexes
with durations of 40 to 120mS and
amplitudes of 0.2 to 4.0 mV (adult) or 0.15 to
4.0 mV (neonatal)

Pacer Rejection — Baseline shift < 0.2 mV
(measured at ECG x 1,000 output)
Pacer Detection — Detects pacer pulses of ±2
mV to ±700 mV with pulse widths of 0.2 to 2
msec and rise times 10% of width not to
exceed 100 µsec.

Sensor Interface —
Red LED drive (max): 175 mA peak at 10%
duty cycle
IR LED drive (max): 105 mA peak at 10%

Measurement Method — Functional
saturation (oxygen saturation of functional
hemoglobin).
SpO

Measurement Mode — Continuous,
episodic (2 minutes, 5 minutes, and 30
minutes) sampling intervals; factory default
setting is continuous.
ST Segment Analysis
Resolution — 0.08 mm
Range — ±9 mm (1 mV = 10 mm)
Leads — ST Segment Analysis continously
performed on up to seven leads.
Alarms — Single lead or multiple leads;
individual leads can be deselected. Alarms
for absolute minimum and maximum ST
levels; changes in ST level over the last 5
minutes.
Displays — ST values: minimum/maximum/
current ST segment deviation and 5 minute
averaged segments for the last 30 minutes.
Measurement Points — Adjustable ST, PR,
and J Points
Trends — Up to 24 hours of trend data can be
displayed in 1.5-, 3-, 6-, 12-, or 24-hour time
tracks.
PATIENT MONITOR DISPLAY
CHARACTERISTICS
ECG Display
Heart Rate Range — 30 to 300 bpm; heart
rates > 300 bpm are displayed as “+++”.
Heart Rate Alarm Limits — High: 5 to 300
bpm, Low: 0 to 200 bpm; alarms
automatically enabled over a range of 40
(adult) or 100 (neonatal) to 300 bpm; heart
rates > 300 bpm are displayed as “+++”.
Accuracy — ±1% or ±2 beats per minute
(whichever is greater).
Numeric Update Rate — Every 3 seconds or
immediately at the onset of an alarm.
Trace Sweep Speeds — 50, 25, 12.5 mm/sec
Display Bandwidth — Two settiings: 0.5 to 30
Hz ±10% (-3 dB) in monitor mode, and 0.05
to 30 Hz ±25% (-3 dB at 50 mm per second)
in extended mode.
