Design Oxygen Saturation Monitoring in Telemedicine Smartphone System (TmSS)

Validation of Oxygen Saturation Monitoring In

www.ajcconline.org • BACKGROUND Pulse oximetry is commonly used to monitor oxygenation in neonates, but cannot detect variations in hemoglobin. Venous and arterial oxygen saturations are rarely monitored. Few data are available to validate measurements of oxygen saturation in neonates (venous, arterial, or pulse oximetric). • PURPOSE To validate oxygen saturation displayed on clinical monitors ...

pulse oximeter oxygen saturation in prediction of arterial oxygen saturation in liver transplant candidates

results roc-derived spo2 threshold of ≤ 94% can predict hypoxemia (pao2 < 60 mmhg) with a sensitivity of 100% and a specificity of 95%. furthermore, there are associations between the roc-derived spo2 threshold of ≤ 97% and detection of hypoxemia (pao2 < 70 mmhg) with a sensitivity of 100% and a specificity of 46%. the accuracy of pulse oximetry was not affected by the severity of liver disease...

Continuous oxygen saturation monitoring during cardiac catheterization in adults.

Arterial hypoxemia may contribute to morbidity during cardiac catheterization. Therefore, we measured arterial hemoglobin oxygen saturation (SaO2) continuously using pulse oximetry in 29 patients (age range, 21 to 83 years) undergoing cardiac catheterization. Baseline SaO2 was 96 +/- 0.4 percent. All patients had a decrease in SaO2 at some time during the procedure. Eleven patients (38 percent)...

How to Design Peripheral Oxygen Saturation (SpO2) and Optical Heart Rate Monitoring (OHRM) Systems Using AFE4403

Pulse Oximeters in clinics have a finger clip type probe that has an LED on one side and a photo detector on the other side. The light emitted from one side of the finger travels through tissue, venous blood and arterial blood and is collected in the detector. Most of the light is absorbed or scattered before it reaches the photo detector in the other side of the finger. The flow of blood is he...
