EUROMUSCULAR TRANSMISSION (NMT) MONITORING
You can set TOF-count alarm limits and alarm recordings in the Alarm Limits table
(see chapter 5, Alarms).
Post-Tetanic Count (PTC)
In this mode, the pod sends stimuli at a 50 Hz rate for
5 seconds, pauses for 5 seconds and then sends single
pulses at a 1 Hz rate. This continues until no twitches are
detected or 20 stimuli are sent. The pod counts the number
of detected twitch responses and displays the post-tetanic
count in the NMT parameter box. The fewer responses
detected, the deeper the neuromuscular blockade.
Measurement intervals are not available in the PTC mode. If you want to return to
automatic measurement cycles after a PTC measurement, select the single or TOF
monitoring mode and restart measurements.
Taking NMT Measurements
To access the NMT Setup menu
1. Click on the NMT parameter box on the
Main Screen (if displayed).
or
1. Press the
Menu fixed key.
2. Click on
Patient Setup.
3. Click on
Parameters.
4. Click on
NMT.
NOTE: There is no AutoSet-function for TOF-count alarm limits.
NOTE:
You can use PTC stimulation to measure deep neuromuscular blockade when
no twitch responses are detected in single or TOF mode.
If PTC measurements start showing a decrease of neuromuscular blockade,
change to Single or TOF mode as soon as possible in order to limit the number
of PTC measurements.
