Arterial blood gas tensions, pH, and carboxyhaemoglobin were measured on 322 occasions in 165 patients and the actual oxygen saturation of the haemoglobin (Sao2) was compared with the ear oxygen saturation (SEO2) recorded during the arterial sampling with a Biox IIA ear oximeter. The overall agreement between SEO2 and Sao2 was good, with a mean difference in saturation (SEO2-Sao2) of + 1.5% (SD...

Background: Eye examination for screening of Retinopathy of Prematurity (ROP), as a painful procedure, causes physiological changes in premature infants. Multisensory stimulation is a non-pharmacological analgesic method which affects physiological measures during painful procedures. Aim: To determine the effect of multisensory stimulation on oxygen saturation in premature infants during eye ex...

INTRODUCTION Pulse oximetry is a useful tool for clinical and investigational purposes for indirect measurements of oxygen saturation [1-3]. Measurement of oxygen saturation with pulse oximetry (SpO2) can be used for evaluation and control of hypoxemia in chronic obstructive pulmonary disease (COPD). As pulse oximetry is a non–invasive device, it can be used instead of arterial blood gases (ABG...

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 ...

OBJECTIVES The purpose of this study was to test if venous blood drawn from femoral access can be used to estimate the central venous oxygen saturation and arterial lactate levels in critically ill patients. METHODS Bland-Altman analysis and Spearman correlations were used to compare the femoral venous oxygen saturation and central venous oxygen saturation as well as arterial lactate levels a...

Regional cerebrovascular oxygen saturation, a quantitative measure of hemoglobin saturation in the combined arterial, venous, and microcirculatory compartments of the brain, can be measured noninvasively with near infrared spectroscopy. We assessed the sensitivity of this aggregate saturation to cerebral hypoxia during transient cerebral hypoxic hypoxia in seven human subjects. Regional cerebro...

=Abstract=Pulse oximetry has recently been introduced as a method for continuous and non-invasive transcutaneous monitoring of arterial oxygen saturation in neonates. The purpose of our study was to determine the reliability, accuracy, and practicability of pulse oximetry for monitoring arterial oxygenation in sick newborn infants. Pulse oximetry oxygen saturation values (SpO2) were compared wi...

background: prematurity is the main cause of death in infants under one years of age and is the main reason for nicu hospitalization. the stressful environment of nicu exposes preterm infants to inappropriate stimuli. this study aimed to determine and compare the mean of heart rate and oxygen saturation of premature infants before and during a designed program in nicu. methods: in a clinical tr...

Background: Preterm birth and admission to neonatal intensive care unit as stressors can cause physiologicalinstability that may lead to prolong hospitalization and mortality. This study aimed to determine the effect of artificialnights and facilitated tucking on the physiological indices of premature infants.Methods: This randomized clinical trial was conducted on 60 preterm ...
