Pulse-oximeter motion artifact
Educational use only. Not clinically reviewed67-year-old man for Pulse-oximeter motion-artifact cross-check. About 7 simulated minutes.
What you will practise
- Cross-check an isolated saturation against signal quality and the patient.
- Inspect pleth quality and compare the oximeter pulse rate with an independent heart rate.
- Review the declared probe, motion, contact, temperature, and local perfusion state.
- Corroborate oxygenation with the whole patient and another oxygenation signal.
- Reassess signal quality, display coherence, oxygenation, and the unresolved clinical context.
