Arterial line location and PPG sensor location

Question

1) From which artery the ABP signal was collected? 2) Where was the PPG device located? Fingertip? What wavelength was used?

Answer 1

https://physionet.org/mimic2/mimic2_waveform_overview.shtml:

• ABP: arterial blood pressure (invasive, from one of the radial arteries)
• ART: arterial blood pressure (invasive, from the other radial artery)

FYI:

• How much more accurate are indwelling arterial catheters compared to standard, non-invasive blood pressure monitoring?
• How much impact does the location of measurement of blood pressure have on the quality of the obtained blood pressure signal?
