Key result
Imaging photoplethysmography achieves >0.93 waveform correlation with reference systems monitoring upper limb blood flow.
Why the study?
Does imaging photoplethysmography accurately monitor blood-flow changes in upper limbs compared to a reference system?
Does imaging photoplethysmography accurately monitor blood-flow changes in upper limbs compared to a reference system?
Imaging photoplethysmography provides a convenient, contactless method for assessing blood flow dynamics with high agreement to existing systems.
May support contactless limb perfusion monitoring; leaves open clinical validation and outcome studies.
> 0.93) between the waveforms measured by both system was observed. Moreover, we found that the response of the optical system on the venous occlusion is uniform at the whole area of the forearm. The new optical technique is more convenient for assessment of the blood flow dynamics because it can be used for measurements in any part of the body. Method of imaging photoplethysmography is very promising for use in equipment intended for evaluation of neurogenic mechanisms of regulation of vascular blood flow.

Zaytsev et al. (2018) studied this question. Imaging photoplethysmography vs. Alternative measurement system was evaluated on Waveform correlation between systems (> 0.93). Imaging photoplethysmography demonstrated a high waveform correlation (>0.93) with a comparator system for monitoring blood-flow changes in the upper limbs.
