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 کاملPulse Oximetry
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 veloci...
متن کاملPulse Oximetry and Plethysmography
Stokes (1) reported that the colored substance in blood carries oxygen. This was followed by Hoppe-Seyler (2), who first crystallized this substance and coined the term hemoglobin. Additionally, it was shown that the pattern of light absorption changes when shaken with air (2). Hertzman (3) described using photoelectric plethysmography of fingers and toes as a dynamic analysis of the peripheral...
متن کاملMethemoglobinemia and Pulse Oximetry
In reviewing the article “Methemoglobinemia: Sudden Dyspnea and Oxygen Desaturation After Esophagoduodenoscopy,” in the August 2004 issue of RESPIRATORY CARE,1 I found the article suggested that, during the esophagoduodenoscopy procedure the patient’s blood oxygen saturation (measured via pulse oximetry) began to drop rapidly, and a saturation of 54% registered on the pulse oximeter while the p...
