Lidco Rapid
Lidco · Model Rapid
Early and fast warning of change. Clear indication of therapeutic route: fluid or drug. Quantification of hemodynamic response particularly stroke volume. More effective use of fluids the right amount at the right time. Contributes to reduced morbidity and complications particularly infections. Reduced length of stay. Reduced overall cost of care. Facilitates SV optimisation while displaying: > Pressures MAP, Systolic and Diastolic > Heart Rate > Stroke Volume and Cardiac Output (Scaled or Actual) > Dynamic Preload parameters Pulse Pressure Variation (PPV) and Stroke Volume Variation (SVV)8 > User selected event response window with continuous trending > History Screen with up to 24 hours of graphical trends > Chart screen for recording numeric data > User adjustable time scales.
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.
No or unstable stroke-volume / cardiac-output value
HighSymptoms: nominal SV / CO dashed or jumps, poor trace-quality indicator.
Root cause: Damped or poor arterial pressure waveform (air, clot, kinked line, under-damped tubing), or the pressure input not zeroed.
Arterial pressure input fault
MediumSymptoms: Pressure trace absent, noisy, or will not zero.
Root cause: Pressure interface cable, the connection to the patient monitor's analog output, or the transducer.
Touchscreen unresponsive
MediumSymptoms: No response or offset touches.
Root cause: Touchscreen controller fault.
Will not run on battery / short run time
MediumSymptoms: Shuts down off mains, battery alarm.
Root cause: Aged internal battery.

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: No CO / SV value
- Check the arterial line for damping, air or a clot and flush it.
- Confirm the pressure transducer is zeroed at the phlebostatic axis.
- Assess the on-screen trace-quality indicator.
- Reseat the pressure interface cable at the LiDCOrapid and the patient monitor.
- Replace the interface cable if the trace is still poor.
Symptom: Pressure trace absent or noisy
- Reseat the interface cable at both ends.
- Verify the patient monitor's analog pressure output is enabled and scaled.
- Re-zero the transducer.
- Inspect the cable and connectors.
- Replace the cable and re-verify a clean arterial trace.
