GE Marquette Responder 3000

Technical Specifications
227 490 02-C Marquette Responder® 3000 81
Signal Display
active backlit VGA color LCD, 3-channel erase
bar display, alphanumeric indication of alarms,
gain, lead, QRS indicator, alarm limits, heart rate,
energy and function key labels

Systole Check
•
heart symbol on display
•
QRS beep (can be switched off)
Heart-Rate Measurement
derivation of trigger pulses from the ECG of either
polarity, adaptive trigger threshold, calculation of
the average rate, storage of the result, 3-digit
display on LCD, alarm limits to the left of the HR
•
measuring range 15 to 300 bpm
•
digit height of HR reading 7.5 mm
•
digit height of alarm limits approx. 2.0 mm
•
minimum amplitude for reliable triggering
>0,3 mV for an ECG signal with a QRS dura-
tion of 80 ms
•
QRS trigger according to AAMI EC 13
•
T-wave suppression up to 1 mV
•
response time to HR changes approx. 5 s
Alarm System
electronic release of alarm
•
when the heart rate violates one of the set alarm
limits (after condition exists for 10 seconds):
audio signal sounds (can be disabled), message
"HR Alarm", alarm recording is initiated (con-
figurable)
•
when at least one of the selected electrodes is
off the patient: audio signal sounds (only when
patient cable is connected), message "Alarm,
Electrode" on display
•
adjustment range for ECG alarm limits: off, 15
to 300 bpm (not overlapping)
•
adjustment range for etCO
2
alarm limits: off, 5
to 76 mmHg
•
digit height of the displayed alarm limits
2.0 mm
Recording
manually initiated continuous ECG recording, or
recording of the delayed ECG signal from memory
(14 seconds, incl. history of 4 seconds) upon alarm
and
alphanumeric annotation of the following
parameters in the paper margin:
−
Heart rate
−
ECG lead
−
filter(s)
−
date, time
−
paper speed
−
reason for recorder start (shock, alarm,
manual, event, auto, 12SL, test, recall, trend,
text)
−
selected energy [J into 50 Ohms]
−
delivered energy
−
SYNC marker
−
user/hospital/practice name
