Key result
Neck photoplethysmography provided heart rate estimates strongly correlated with finger PPG (R=0.862, MAE=1.27 BPM), but oxygen saturation measurements were not accurately predicted.

Neck PPG may support alternative-site HR monitoring; leaves open SpO2 accuracy and clinical validation.

Does neck photoplethysmography accurately estimate heart rate and oxygen saturation compared to finger photoplethysmography in healthy subjects?
Neck photoplethysmography shows promise as an alternative location for monitoring heart rate and respiratory rate, but it is not currently accurate for SpO2 estimation.
Effect estimate: R=0.862
García-López et al. (2018) conducted an observational in Healthy subjects. Neck photoplethysmography (PPG) vs. Finger photoplethysmography (PPG) was evaluated on Heart rate (HR) estimation (R=0.862). Neck photoplethysmography provided heart rate estimates strongly correlated with finger PPG (R=0.862, MAE=1.27 BPM), but oxygen saturation measurements were not accurately predicted.
