Nmt Setup - GE Datex-Ohmeda S/5 Technical Reference Manual

Datex-Ohmeda S/5 Anesthesia and Critical Care Monitors
Timeouts is a cumulative number that indicates how many times the module has not responded to the
monitor's inquiry.
Bad checksums is a cumulative number that indicates how many times communication from the module to
the monitor has failed.
Bad c-s by mod is a cumulative number that indicates how many communication errors the module has
detected.
The monitor starts counting these items at power up and resets to zero at power off. The non-zero values do
not indicate a failure, but the continuous counting (more than 5 per second) indicates either a serial
communication failure, or a module not in place. Also failures in other modules may cause these numbers to
rise or be set to 32769.
RAM indicates the state of the RAM memory.
ROM indicates whether the checksum in the EPROM is in accordance with the software calculated value.
EEPROM indicates if the values stored in the permanent memory are valid.
The state is either OK, Fail or ? (module not in place or a communication error).

4.8.1 NMT Setup

Start-up is for starting the neuromuscular
transmission measurement.
Stop/Continue is for stopping/continuing the
measurement.
Stimulus Mode is for changing the stimulus mode.
The choices are: TOF - Train of Four, DBS -Double
Burst Stimulation or ST - Single Twitch mode.
Cycle Time is for changing the time interval for NMT
measurement. The choices are:
for TOF and DBS: Manual and from 10 sec to 15 min.
for ST: 1, 10 and 20 sec.
Current is for changing the stimulus current strength.
The current is either supramaximal (automatic
start-up search) or manually selected.
Pulse Width is for selecting the desired pulse width.
The choices are: 100, 200 or 300 µs.
