Detection of decreases in the amplitude fluctuation of pulse photoplethysmography signal as indication of obstructive sleep apnea syndrome in children
TL;DR: Results indicate a correlation between apneic events and DAP events, which suggests that D AP events could provide relevant information in sleep studies, and PPG signals might be useful in the diagnosis of OSAS.
Communications Frequency Analysis of the Peripheral Pulse Wave Detected in the Finger with a Photoplethysmograph
M. H. Sherebrin,R. Z. Sherebrin +1 more
TL;DR: In this paper, a photoelectric plethysmograph was used to determine how the pulse shape varied with age using 54 subjects in three age groups, 10-29, 30-59, and 60-89 years.

Feasibility of Imaging Photoplethysmography
TL;DR: The outcome explicitly reveals the imaging PPG is able to detect blood perfusion in a illuminated tissue and indicates the vascular distribution and the blood cell response to individual wavelength LED.
Journal ArticleDOI
The Use of Joint Time Frequency Analysis to Quantify the Effect of Ventilation on the Pulse Oximeter Waveform
TL;DR: Joint time frequency analysis of the pulse oximeter waveform can be used to determine the respiratory rate of ventilated patients and to quantify the impact of ventilation on the waveform.

Photoplethysmography. Part 2. Influence of light source wavelength.
Lars-Göran Lindberg,P A Oberg +1 more
TL;DR: Analysis of the measurement results provided evidence that the use of shorter wavelengths in PPG (AC) for monitoring skin perfusion changes could be applicable, and temperature-dependent optical characteristics of blood-free skin tissue may explain the limited ability of the DC component of PPG to monitor skin perfusions changes.
