Arterial-pressure transducer artifact
Educational use only. Not clinically reviewed58-year-old man for Repair under neuraxial anesthesia. About 6 simulated minutes.
What you will practise
- Verify an implausible invasive pressure with an independent cuff result before treating the patient.
- Recognize and remove the hydrostatic pressure offset by recording level-and-zero intent.
- Use waveform morphology to identify and correct the over-damped pressure system.
