Key result
Oscillometric blood flow measurement correlated with Doppler-measured blood flow in the brachial artery (r = 0.716), suggesting it can quantify blood flow non-invasively after calibration.
Why the study?
Does an oscillometric blood flow measurement system accurately determine arterial blood flow compared to Doppler ultrasound in subjects evaluated for peripheral arterial embolism?
Observational (n=32)

Effect estimate: r = 0.716
An oscillometric approach can non-invasively quantify brachial artery blood flow, showing good correlation with Doppler measurements.

May support calibrated oscillometric flow assessment; hypothesis-generating without prospective validation in embolism.
Liu et al. (2009) conducted an observational in Peripheral arterial embolism (n=32). Oscillometric blood flow measurement vs. Doppler-measured blood flow was evaluated on Correlation between oscillometry- and Doppler-based blood flow measurements (r = 0.716). Oscillometric blood flow measurement correlated with Doppler-measured blood flow in the brachial artery (r = 0.716), suggesting it can quantify blood flow non-invasively after calibration.
