INTRODUCTION Measurement of oxygen saturation by pulse oximetry (SpO2) is frequently performed during exercise testing of patients with COPD to monitor for hypoxemia. The purpose of this study was to assess the accuracy and precision of pulse oximetry during exercise. We hypothesized that the SpO2 would more closely reflect oxygen saturation as measured by co-oximetry (SaO2) when it was correct...

Pulse oximetry (Spo2) is a simple, noninvasive method that is widely used to determine oxygen saturation in patients undergoing surgical procedures. Artificial acrylic nails have recently become fashionable to strengthen and lengthen nails. This study investigates the effect of unpolished acrylic nails on the measurement of oxygen saturation by pulse oximetry. Data were collected during a 3-mon...

the case report that will be presented is an inherited methemoglobinemia , during general anesthesia of 36year old patient and was suspected by some clinical xamination such a decrease oxygen saturation in pulse oximetry and a normal finding in abg sample that have been prepared at the preparation of patient for anesthesia .so we are going to write about this problem in the perioperative period...

background : hepatopulmonary syndrome (hps) refers to arterial hypoxemia caused by pulmonary vasodilation, which is a consequence of portal hypertension. hps is associated with increased morbidity and mortality; thus, it is important to diagnose this entity as soon as possible for treatment to be administered. materials and methods: in a cross-sectional study, 40 children (6 months to 14 years ...

Introduction: Several pathological conditions can reduce blood supply to the organs, among which burns can be mentioned. By developing the volume depletion and reducing the cardiac contractility, burns can cause hypoperfusion. Further, in ICUs, since the finger pulse oximetryis commonly used instead of the measurement of the nasal alar oxygen saturation, the use of finger probe restricts pulse ...

Pulse oximetry is a useful way to monitor oxygen saturation in patients in a variety of clinical settings. Nurses need to understand the principles of oxygen transport and delivery to use pulse oximetry effectively in clinical practice.

Multi-wavelength photometers, blood gas analysers and pulse oximeters are widely used to measure various oxygen-related quantities. The definitions of these quantities are not always correct. This paper gives insight in the various definitions for oxygen quantities. Furthermore, the possible influences of dyshaemoglobins and fetal haemoglobin on the accuracy of pulse oximetry are discussed. As ...

The use of supplemental oxygen plays a vital role in the care of the critically ill preterm infant, but the unrestricted use of oxygen can lead to unintended harms, such as chronic lung disease and retinopathy of prematurity. An overly restricted use of supplemental oxygen may have adverse effects as well. Ideally, continuous monitoring of tissue and cellular oxygen delivery would allow clinici...

OBJECTIVE To evaluate pulse oximetry for detection of congenital cyanotic heart disease in sick neonates using echocardiography as gold standard. METHODS Pulse oximetry readings were taken at admission from 950 neonates from right upper limb and either foot with infant breathing room air. Pulse oximetry was considered abnormal if oxygen saturation at room air measured <90% or difference betwe...

BACKGROUND Peripheral oxygen saturation (SpO(2)) measured by pulse oximetry is widely used in clinical practice, but its fluctuations over the course of the 24 h of a day have not been explored at length. Recently, we reported that children hospitalized due to non-cardiopulmonary causes had a circadian variation in SpO(2). This finding needed to be corroborated in healthy children, which is the...
