Draeger Infinity CNAP SmartPod
Dräger · Model Infinity CNAP SmartPod
Integrates light-emitting diode & detector into sensor cuff. Blood pressure can then be calculated beat-to-beat, after calibration with the built-in standard oscillometric measurement (NBP) of the monitor – and a high resolution, real-time arterial pressure waveform is displayed. Bridges the gap between NBP and arterial line. The CNAP solution provides the clinical utility (i.e., beat-to-beat vigilance) of the invasive arterial line – with user convenience and simplicity of a noninvasive cuff. It bridges the gap in many situations when NBP is not enough, and an arterial line is just too invasive and complicated.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Pressure / haemodynamic channel will not zero or reads wrong
HighSymptoms: IBP / PiCCO / CNAP trace offset, "zero required" persists, values implausible.
Root cause: Transducer not open to atmosphere during zero, a damaged cable, or a module input fault.
Module / pod not recognised by the host
MediumSymptoms: Host monitor does not display the module or pod.
Root cause: Docking / pod connector or cable fault.
Noisy or absent waveform
MediumSymptoms: Damped, noisy or flat trace.
Root cause: Air / clot in the line, a loose connection, or a cable fault.
Cable / connector wear
LowSymptoms: Intermittent signal with cable movement.
Root cause: Worn patient cable.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Will not zero / noisy waveform
- Open the transducer to atmosphere and re-zero.
- Flush the line and clear any air or clot.
- Swap in a known-good cable.
- Dock the module on another host to isolate module vs host.
- Replace the cable or refer the module.
Symptom: Module / pod not recognised
- Reseat the module / pod at the host or rack.
- Inspect the docking connector for bent pins.
- Try it in another host or slot.
- Try a known-good module in this slot.
- Refer the module or the host slot as isolated.
