Dräger Infinity M300 Series Instructions For Use Manual page 220

System configuration
ANSI/AAMI/ IEC 60601- 2-27:2011
QRS detection amplitude
QRS detection amplitude: 0.5 to 5.0 mVp-v RTI
QRS threshold detection duration:
Adult: 70 to 120 ms
Pediatric: 40 to 120 ms
Configuring the QRS threshold to Low may extend the QRS detection amplitude to as low as 0.17 mVp-
v RTI.
WARNING
Risk of inaccurate HR value. If the QRS setting is set to Low in the presence of HR artifact, the
associated HR value may be inaccurate.
To avoid an inaccurate HR value, it is recommended to set the QRS threshold setting to Normal.
ECG QRS processing settings
Gain/Scale column
For all ECG waveforms: 0.25, 0.5, 1 (de-
fault), 2, 4, 8 mV/cm
The M300/M300+ uses an AAMI-compliant
regular QRS threshold when you select a
scale of 1, 2, 4, or 8 mV/cm. If you select a
scale of 0.25 or 0.5 mV/cm, the
M300/M300+ lowers the detection thresh-
old, and the AAMI requirement is not met.
