Abstract: We describe an evaluation of photoplethysmography (PPG) signals with two wavelengths channels (infrared and red) using a wrist-worn sensor for the estimation of heart rate variability (HRV) ...
NASHVILLE, Tenn. -- Racial biases persist in the use of pulse oximetry devices for patients with acute hypoxemic respiratory failure (AHRF) requiring very high levels of oxygen support, a ...
Conclusions: SpO2 and PR measurements may be inaccurate across all skin pigmentation groups, breaching U.S. Food and Drug Administration guidance and industry standard thresholds. Pulse oximeters ...
Abstract: In this work, a detection and classification method for sleep apnea and hypopnea, using photopletysmography (PPG) and peripheral oxygen saturation (SpO 2) signals, is proposed. The detector ...
The objective of this study was to compare the influence of continuous intravenous infusion of tramadol alone, or tramadol combined with lidocaine and ketamine, on minimum alveolar concentration of ...
