ExSpiron 2Xi
Senzime AB (Publ.) · Model RMI-54000
A noninvasive device designed to continuously measure a patient's tidal volume, minute ventilation, and respiratory rate via impedance pneumography. Designed to be connected to the ExSpiron PadSet via the ExSpiron Patient Cable, the ExSpiron 2Xi Monitor provides a measurement of a patient's respiratory parameters, while also incorporating alarms. The ExSpiron 2Xi Monitor can be integrated into a medical facility's nurse call system.
Intended use: A mains electricity (AC-powered) device designed to measure continuously a patient's tidal volume (volume of gas inhaled by the patient during each respiration cycle) or minute volume (the tidal volume multiplied by the rate of respiration for 1 minute) for the evaluation of the patient's ventilatory status. It may also be used to measure the tidal volume, minute volume, and respiration rate delivered to a patient via the expiratory ports of resuscitation devices, such as transport ventilators and resuscitators, to evaluate their performance. The device may incorporate high and low tidal volume alarms.
Key tips
- ·Never disable a low-pressure/circuit-disconnect alarm while troubleshooting - silence it, don't disable it.
- ·Verify the O2 supply source and pressure before assuming an internal fault.
- ·Circuit type must match the patient population (adult/pediatric/neonatal) - a mismatched circuit invalidates delivered volumes.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Exhalation valve leak / failure
HighSymptoms: Low exhaled tidal volume, high leak alarm, inability to maintain PEEP.
Root cause: Diaphragm/valve degraded by secretions and cleaning cycles.
Flow / pressure sensor drift
MediumSymptoms: Inaccurate delivered volume, false volume/pressure alarms.
Root cause: Sensor contamination or aging of differential-pressure transducer.
Power supply / battery failure
HighSymptoms: Unexpected shutdown, persistent low-battery alarm.
Root cause: Aged internal battery or failed PSU.
O2 blender / mixer fault
MediumSymptoms: FiO2 out of range, oxygen alarm.
Root cause: Failed solenoid or proportional valve in blender.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily pre-use check: self-test, circuit integrity, alarm function
- ·Scheduled circuit and inspiratory filter replacement per manufacturer interval
- ·Flow and pressure sensor calibration verification
- ·Battery load test and runtime check
- ·Annual full PM and electrical safety test
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Exhalation valve leak / failure
- Confirm the presentation - typically low exhaled tidal volume, high leak alarm, inability to maintain PEEP - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: diaphragm/valve degraded by secretions and cleaning cycles.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the exhalation valve assembly per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
