Infinity M300/M300+ Features for VG2.4
This section contains the Infinity M300/M300+ features for the VG2.4 release. For specific information
about the new M300+, refer to "Infinity M300+" on page 18.
QRS Threshold
Depending on the software versions running on the ICS and the M300/M300+ devices, the procedure you
follow to set the QRS threshold on the M300/M300+ will differ:
If ICS is VG2.1.1 or later, and the M300/M300+ is VG 2.4 or later, you set the QRS threshold by a menu
selection, either Normal or Low
If ICS is VG2.1 or earlier, or the M300 is VG2.3 or earlier, the QRS threshold is linked to the ECG gain
and the QRS threshold buttons are greyed out. The following relationships apply:
– Setting the gain to 1, 2, 4, or 8 mV/cm, automatically sets to the QRS threshold to Normal.
– Setting the gain to 0.5 or 0.25 mV/cm, automatically sets the QRS threshold to Low.
To set the QRS Threshold using ICS VG2.1.1 and M300/M300+ VG2.4
From the Main ICS screen:
1Click System setup on the ICS.
2Click Layouts.
3Click one of the following:
–Normal to detect QRS complexes of normal amplitude.
–Low to detect QRS complexes of low amplitude.
NOTE
Patient admitted on M300/M300+ VG2.4:
Changes to QRS/ARR processing leads and gain settings do not change QRS threshold settings.
Patient admitted on M300 VG2.3 and earlier:
– Changes to QRS/ARR processing leads and gain settings will alter the QRS threshold settings be-
tween Normal and Low.
– When selecting one or two QRS/ARR processing leads, a gain setting of < 1mv on either lead, sets
the ICS QRS threshold to Low.
– When selecting one or two QRS/ARR processing leads, a gain setting of > 1mv on all leads, sets the
ICS QRS threshold to Normal.

Supplement – Infinity M300 and M300+ Series – VG2.4 11
Infinity M300/M300+ Features for VG2.4
To set the QRS Threshold using earlier ICS and M300 versions
For ICS 2.1 or earlier, or M300 VG2.3 or earlier, from the Main ICS screen:
1Click System setup on the ICS.
2Click Layouts.
3Click the dropdown arrow of the appropriate Gain/Scale Channel.
4Select the appropriate Gain value:
– Select a value of 1,2,4 or 8 mV/cm to set the QRS threshold to Normal.
– Select a value of 0.5 or 0.25 mV/cm to set the QRS threshold to Low.
QRS dectection 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-
vRTI.
ECG QRS processing settings
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.
Gain/Scale column mV/cm Detection threshold
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.

12 Supplement – Infinity M300 and M300+ Series – VG2.4
M300/M300+ Arrhythmia processing
Arrhythmias are identified using an internal detection process. This process does the following:
– Filters out ECG signal artifacts
– Detects the beat pattern
– Classifies the beat pattern
– Detects the rhythm
When arrhythmia analysis is enabled, multiple alarm conditions may occur simultaneously. Announcing
all the alarm conditions would cause alarm fatigue and prevent the clinician from addressing the most
serious condition. For this reason, the arrhythmia conditions are prioritized and only the highest priority
alarm event shall annunciate. The priority order of the arrhythmia events is based on the default priority
defined in the algorithm and the alarm grade configured by the user.
Based on this detection process, arrhythmias and other associated events are reported in the following
order of severity:
1ASY (asystole)
2VF (ventricular fibrillation)
3VTACH (ventricular tachycardia)
4RUN (ventricular run)
5AIVR (accelerated idioventricular rhythm)
6SVT (supraventricular tachycardia)
7CPT (ventricular couplet)
8BGM (bigeminy)
9TACH (tachycardia)
10 Brady (bradycardia)
11 Pause (sinus pause)
12 ARR artifact
In addition to storage as events, the two high priority alarms, ASY and VF, are also stored and displayed
in the trends of the ICS.
An arrhythmia with a high grade alarm configuration has a higher priority than an arrhythmia with a
medium, low or disabled alarm grade configuration. An arrhythmia with a medium grade alarm
configuration has a higher priority than an arrhythmia with a low or disabled alarm grade configuration. An
arrhythmia with a low grade alarm configuration has a higher priority than an arrhythmia with a disabled
alarm configuration.
The priority for arrhythmia events configured with the same alarm grade follows the arrhythmia hierarchy
list. When arrhythmia artifact is present (ARTF) at 100% artifact level, no arrhythmia events are
recognized except for bradycardia and ventricular fibrillation. If sinus tachycardia and ventricular
tachycardia are configured at the same alarm grade, a ventricular tachycardia will take priority if the rate
is high enough and the beats are classified as ventricular beats.

Supplement – Infinity M300 and M300+ Series – VG2.4 13
Infinity M300/M300+ Features for VG2.4
ECG signal processing and display
The M300/M300+ calculates heart rates within a range of 15 beats to 300 beats per minute, using the R-
R intervals of the last 10 seconds. This calculation excludes the two longest and two shortest R-R
intervals. The M300/M300+ averages the remaining intervals and displays the result as the current heart
rate in the heart rate parameter box.
During dual-channel processing, a weight is assigned to each channel depending on its level of artifact.
The channel with less artifact always receives the greater weight. When a channel exceeds a certain level
of artifact, it is excluded from the composite signal, and the M300/M300+ shifts to single-channel
processing. If both channels experience excessive artifact, the message ECG artifact appears until at
least one channel is sufficiently free of artifact.
During artifact, asterisks (* * *) replace the heart rate value. When the artifact clears, QRS processing
resumes without initiating a relearning phase.
Patient preparation for ECG monitoring
The following tips provide optimal ECG monitoring results but must never replace hospital-approved prac-
tices or the recommendations of the electrode manufacturer.
Follow hospital procedures for proper skin preparation. Dräger recommends Ag/AgCl disposable elec-
trodes. Never use disposable electrodes after their expiration date and make sure that there is enough gel
and that the gel has not dried out.
If QRS detection threshold is configured to Low, P- and T-waves with amplitudes exceeding 0.17 mV may
be interpreted as QRS complexes. P- and T-waves with amplitudes exceeding 0.35 mV when QRS detec-
tion threshold is configured to Normal, may be interpreted as QRS complexes. The algorithm has imple-
mented safeguards to reduce the occurrence of P- and T-wave detection as QRS complexes, however
additional steps can be taken to prevent and/or troubleshoot occurrence: .
– To allow detection of low heart rate conditions under these circumstances, place the lead with the high-
est R-wave in ECG Channel number 1.
– If P- and T-waves are misinterpreted, confirm that the lead with highest R-wave is in ECG Channel
number 1 and set QRS detection threshold to Normal.
– If P- and T-waves continue to be misinterpreted, reposition the electrodes or use a pulse oximeter to
monitor the pulse rate.
NOTE
For heart rates of 300 bpm and greater, the mon-
itor may display VF and not the expected +++ as
the parameter value.

Infinity M300/M300+ Features for VG2.4
14 Supplement – Infinity M300 and M300+ Series – VG2.4
To maintain a clear signal, change electrodes every 24 to 48 hours or more often when the following
occurs:
– ECG signal degradation
– Excessive patient perspiration
– Skin irritation
Consider the following when selecting electrode sites:
–Surgery –keep electrodes as far from the surgical site as possible, while maintaining a clinically useful
lead configuration.
–Burn patients –use sterile electrodes. Clean the equipment thoroughly and follow hospital infection
control procedures.
ECG precautions
WARNING
Do not rely solely on the ECG when monitoring seizure-prone patients. Electrical artifacts of non-
cardiac origin, such as seizure, may prevent detection of certain arrhythmias.
