We present a novel method for estimating respiratory rate in real time from the photoplethysmogram (PPG) obtained from pulse oximetry. Three respiratory-induced variations (frequency, intensity, and amplitude) are extracted from the PPG using the Incremental-Merge Segmentation algorithm. Frequency content of each respiratory-induced variation is analyzed using fast Fourier transforms. The proposed Smart Fusion method then combines the results of the three respiratory-induced variations using a…

Estimation of respiratory volumes from the photoplethysmographic signal. Part I: experimental results
TLDR
To evaluate the possibility of respiratory-volume measurement using photoplethysmography (PPG), PPG signals from 16 normal volunteers are collected, and the respiratory-induced intensity variations (RIIV) are digitally extracted, finding that the amplitude of the RIIV signal is related to the respiratory volume.
Comparison of respiratory-induced variations in photoplethysmographic signals
TLDR
Correlations between respiratory-induced variations extracted from PPG and simultaneous respiratory signals are investigated and it is indicated that the period of the systole and diastole correlates weakly with respiration; the amplitude of the diastoles has a stronger correlation with resppiration than the amplifies of the Systole.
