A New Family of Sensors for Pulse Oximetry
نویسندگان
چکیده
Since the early 1980s, when pulse oximetry was introduced, this noninvasive method of monitoring the arterial oxygen saturation level in a patient’s blood (SpO2) has become a standard method in the clinical environment because of its simple application and the high value of the information it gives nurses and doctors. It is as common in patient monitoring to measure the oxygen level in the blood as it is to monitor heart activity with the ECG. In some application areas, like anesthesia in a surgical procedure, it is mandatory for doctors to measure this vital parameter. Its importance is obvious considering that a human being cannot survive more than five minutes without oxygen supply to the brain.

PURPOSE OF REVIEW This article reviews the development of novel reflectance pulse oximetry sensors for the esophagus and bowel, and presents some of the techniques used to analyze the waveforms acquired with such devices. RECENT FINDINGS There has been much research in recent years to expand the utility of pulse oximetry beyond the simple measurement of arterial oxygen saturation from the fin...
متن کاملEvaluation and Improvement of Knowledge of Medical staff on Pulse Oximetry in Educational Hospitals
Background: Pulse Oximeter monitoring has become so common over previous decades that in some health care units, blood oxygen level is now considered as the fifth vital sign. However, it seems there is still some lack of knowledge and/or experience among medical staff operating pulse oximeter and interpreting its results. The aim of this study was to investigate and compare the knowledge on Pul...

متن کاملAccuracy of fetal pulse oximetry and pitfalls in measurements.
Pulse oximetry is a technique for estimating arterial oxygen saturation continuously and non-invasively. Reflectance pulse oximetry might become useful for monitoring the fetus during labour but it is much more susceptible to all kinds of physiological variations than the well-established transmission pulse oximetry for neonatal or adult monitoring. This review focuses on the accuracy of reflec...
