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...

Background: Congenital heart diseases, which are asymptomatic at birth, are the most important causes of infant mortality. This study aimed to evaluate the role of pulse oximetry in the early detection of congenital heart diseases among newborns.Methods: In this cross-sectional descriptive study, 1230 newborns who were born in university hospitals in an urban area of Iran were placed unde...

introduction inhalation sedation is used for pain and anxiety control in dentistry. hypoxia is the most important side effect which can be detected using pulse oximetry, however, there are different opinions about the use of this instrument. this study has been designed to investigate this subject. methods and materials in this study, 32 adult patients from periodontal surgical department were ...

background & aim : pulse oximetry is a frequently used and standard non-invasive method for monitoring oxygen (o2)-saturation in blood. many factors including dark skin and pigmentation may effect on rate of saturation of the blood oxygen absorbed by pulse oximetry. the effect of nail polish and/or henna color on blood oxygen has not been yet identified and the present study has been carried ou...

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...

background: delayed or missed diagnosis of critical and cyanotic congenital heart disease (chd) in asymptomatic newborns may result in significant morbidity and mortality. the aim of this study was to determine the accuracy of pulse oximetry screening  performed on the first day of life for the early detection of critical and cyanotic chd in apparently normal newborns. methods: this cross-secti...

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,...

background: one of the main problems especially in operating room and monitoring devices is measurement of blood pressure (bp) by sphygmomanometer cuff. objective: in this study we designed a new method to measure bp changes continuously for detecting information between cuff inflation times by using vital signals in monitoring devices. this will be achieved by extraction of the time difference...
