12.2.3.9 System response time
The system response time of the microMediCO
2
and fabian HFO together is typically 3.1 seconds.
This includes the following timing sequences:
• 2.7 seconds delay time
• 0.2 seconds rise time from the microMediCO
2
and
• 0.2 seconds response time from the fabian HFO.

Self-maintenance (SFM) interval
Self-Maintenance (SFM) is performed only during measurement mode. The module performs one or
more of the following:
• Ambient pressure measurement
• Auto zero (AZ)
• Flow test
SFM is triggered:
• During the first hour after entering measurement mode, periodically for durations of 10 seconds
at a rate which limits the total time consumed by SFMs to less than 2% of the time in which
active measurements are taken. Following the first hour after entering measurement mode,
periodically for durations of 10 seconds at a rate of once per hour.
• A significant temperature change measured by the module (not less than 8°C from the
temperature at the time that the last AZ was detected).
• A significant ambient pressure change (not less than 18 mmHg relative to the last ambient
pressure measurement) for a period of 30 seconds
.
The module prevents the triggering of an SFM in the following situations:
• In case of purging until the end of this state.
• During a breath absence period which follows a valid breath.
• While waiting a minimum of 20 seconds for host SFM enable command. (After the 20-second
opportunity given to the host to schedule the SFM passes, the module schedules the SFM
according to a priority determined by current conditions).
Periodic service
Periodic maintenance is recommended according to operating hours:
• The CO
2
pump should be replaced every 30,000 operating hours.
• A calibration should be performed as described in section “12.2.3.3: MicroPod calibration
interval".
Limited Operating life
The following parts of a MicroPod with a microMediCO
2
capnography board will require replacement
after a set period:
• The CO
2
Pump should be replaced every 30,000 operating hours.
• The I.R. Source should be replaced every 30,000 operating hours.
