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...

BACKGROUND Cognitive impairment is one of the main consequences of obstructive sleep apnea (OSA) and is usually attributed in part to the oxidative stress caused by intermittent hypoxia in cerebral tissues. The presence of oxygen-reactive species in the brain tissue should be produced by the deoxygenation-reoxygenation cycles which occur at tissue level during recurrent apneic events. However, ...

Background and Aims One potential complication of acute respiratory distress syndrome (ARDS) is reduced dynamic compliance, saturation for peripheral oxygenation (SpO2) and increased sputum in patients that are mechanically ventilated. Airway clearance technique is the treatment given for patients on mechanically ventilator with ARDS. The purpose of the case series is to know the immediate effe...

Introduction: Shivering after anaesthesia and surgery is a common complication. Different methods are used for control of shivering in the recovery room. The opioids such as pethidine are very common in shivering control. Pethidine can be induced apnea, respiratory depression and nausea &vomiting. The respiratory rate and spo2 can lead to more rapid diagnosis and treatment of serious hypoxemia ...

UNLABELLED Oxygen is a neonatal health hazard that should be avoided in clinical practice. In this review, an international team of neonatologists and nurses assessed oxygen saturation (SpO2 ) targeting in preterm infants and evaluated the potential weaknesses of randomised clinical trials. CONCLUSION SpO2 of 85-89% can increase mortality and 91-95% can cause hyperoxia and ill effects. Neithe...

Introduction:  One ofdiagnostic criteria for Acute Lung Injury and Acute Respiratory Distress Syndrome is  pao2/fio2 (PF) ratio 300 for ALI or 200 for ARDS. This criteria requires invasive arterial sampling. Measurement of Spo2/Fio2 (SF) ratio by pulseoximetry may be a reliable non invasive alternative to the PF ratio.   Methods and Materials: In a cross sectional study we enrolled 105 sample o...

The effects of inhalation anesthesia (2% isoflurane, sevoflurane, or enflurane) and intraperitoneal anesthesia with pentobarbital (65 mg/kg) were compared in rats using an electrocardiogram (ECG) and determination of blood oxygen saturation (SPO2) levels. Following inhalation anesthesia, heart rate (HR) and SPO2 were acceptable while pentobarbital anesthesia decreased HR and SPO2 significantly....

We have developed a computer program that estimates venous admixture (intra-pulmonary shunt) from four measurements: haemoglobin concentration, end-tidal carbon dioxide tension (PE'CO2), fractional inspired oxygen concentration (FIO2) and pulse oximetry (SpO2). The formula was tested on patients in an intensive therapy unit by using it to estimate shunt while it was measured simultaneously by a...

OBJECTIVES This study was undertaken to evaluate whether the surgeons' oxygen saturation of hemoglobin was affected by the surgical mask or not during major operations. METHODS Repeated measures, longitudinal and prospective observational study was performed on 53 surgeons using a pulse oximeter pre and postoperatively. RESULTS Our study revealed a decrease in the oxygen saturation of arter...

We have measured arterial oxygen saturation (SpO2) continuously overnight in 13 non-pregnant (NP), 13 pregnant normotensive (NPIH) and 15 pregnant patients with a diagnosis of pregnancy-induced hypertension (PIH). The two pregnant groups did not differ in duration of pregnancy (> 35 weeks) and none was in labour. There was no significant difference in age between these three groups. Mean SpO2 i...
