Pulse Oximetry

چکیده
The principal advantage of optical sensors for medical applications is their intrinsic safety since there is no electrical contact between the patient and the equipment. (An added bonus is that they are also less suspect to electromagnetic interference). This has given rise to a variety of optical techniques to monitor physiological parameters: for example, the technique of Laser Doppler velocimetry to measure red blood cell velocity. However, in this lecture course we will concentrate on the technique of pulse oximetry for the non−invasive measurement of arterial oxygen saturation in the blood (although a second use of the technology will be discussed right at the end of the course).

Evaluation 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 کاملCan we Replace Arterial Blood Gas Analysis by Pulse Oximetry in Neonates with Respiratory Distress Syndrome, who are Treated According to INSURE Protocol?
Neonates with respiratory distress syndrome (RDS), who are treated according to INSURE protocol; require arterial blood gas (ABG) analysis to decide on appropriate management. We conducted this study to investigate the validity of pulse oximetry instead of frequent ABG analysis in the evaluation of these patients. From a total of 193 blood samples obtained from 30 neonates <1500 grams with RDS,...
متن کاملComparative study of pulse oximetry, physical examination and echocardiography results in the diagnosis of congenital heart defects in neonates in the first 24 hours of life
Introduction: Congenital heart disease is the most common congenital anomaly. About 50% of Neonates with congenital heart disease are asymptomatic in the first few days of life and are not diagnosed on initial examination. Pulse oximetry is a non-invasive method that can show the percentage of oxygen saturation in the blood and congenital heart disease. Methods: This was a descriptive cross-se...
