Settling Time Constant: <10 seconds
Alarm Signal Generation Delay: 5 seconds
Averaging Time: 1 second
Minimum measurement time: See the probe’s Instructions for Use to obtain minimum measurement
times for accurate readings. The HeartStart MRx does not add any clinically significant time to obtain
accurate readings.
EtCO

Range: 0 to 99 mmHg at sea level
Resolution: 1 mmHg (0.1kPa)
Accuracy: For values between 0 and 38 mmHg: +
2 mmHg. For values between 39 and 99 mmHg:
+
5% of reading + 0.08% for every 1 mmHg above 38 mmHg. Values read at sea level after >20 min
warm up. For breath rates above 80 and EtCO
2
values > 18 mmHg, accuracy is 4mmHg or +12% of
reading, whichever is greater.
Drift of Measurement Accuracy: Over any 24-hour period, the accuracy claims listed above are
maintained.
The accuracy specification is maintained to within 4% for the following gas mixtures (all values are in
Vol. %).
Rise Time: 190 ms maximum @ 10ml/min
System Response Time (with a standard length FilterLine): 2.9 seconds typical - includes the delay
time and rise time (10% to 90%) in response to a step change in the CO

concentration
Alarm Delay Time: 5.2 seconds, standard deviation 0.08 seconds (includes the 2.9 second FilterLine
delay).
