BACKGROUND Seasonal variability on obstructive sleep apnea has already been studied by polysomnography in children. Winter and spring season emerged as critical periods. No data are currently available for pulse oximetry performed at home. The aim of our study was to evaluate the effect of seasonality and age on the results of at-home pulse oximetry performed in children referred for suspected ...

OBJECTIVE For children with cyanotic congenital heart disease or acute hypoxemic respiratory failure, providers frequently make decisions based on pulse oximetry, in the absence of an arterial blood gas. The study objective was to measure the accuracy of pulse oximetry in the saturations from pulse oximetry (SpO2) range of 65% to 97%. METHODS This institutional review board-approved prospecti...

PURPOSE Up to 53% of cardiac surgery patients experience postoperative neurocognitive decline. Cerebral oximetry is designed to detect changes in cerebral tissue saturation and therefore may be useful to predict which patients are at risk of developing neurocognitive decline. METHODS This is a retrospective analysis of a prospective study originally designed to determine if treatment of cereb...

OBJECTIVE To investigate implementation of outpatient pulse oximetry among children with pneumonia, in Malawi. METHODS In 2011, 72 health-care providers at 18 rural health centres and 38 community health workers received training in the use of pulse oximetry to measure haemoglobin oxygen saturations. Data collected, between 1 January 2012 and 30 June 2014 by the trained individuals, on childr...

Why Nellcor Developed the OxiMax Pulse Oximetry System The introduction of the OxiMax Pulse Oximetry System brought Nellcor’s fifth-generation pulse oximetry technology to market and marked a fundamental shift in one of the design tenets of pulse oximeters. In the first four generations of Nellcor pulse oximetry, beginning with the N-100 Pulse Oximeter introduced in the early 1980s, we focused ...

STUDY OBJECTIVE Determine the utility of nocturnal oximetry as a screening tool for sleep apnea-hypopnea syndrome (SAHS) compared with polysomnography (PSG). DESIGN Cost-effectiveness analysis based on retrospective review of overnight sleep studies. SETTING United States Air Force tertiary teaching hospital. PATIENTS One hundred consecutive patients evaluated for SAHS by overnight sleep ...

BACKGROUND The British Thoracic Society report on the diagnosis and treatment of the sleep apnoea/hypopnoea syndrome (SAHS) suggests that, if the pulse oximetry baseline oxygen saturation is above 90%, then 15 4% oxygen desaturation/hour in bed will diagnose SAHS requiring treatment. The diagnostic outcome of applying these guidelines has been studied. METHODS One hundred patients referred to...
