BACKGROUND In this pilot study we explored the suitability of the esophagus as a new measuring site for blood oxygen saturation (Spo(2)) in neonates. METHODS A new miniaturized esophageal pulse oximeter has been developed. Five patients (one child and four neonates) were studied. RESULTS Spo(2) values were obtained in the esophagus of all patients. A Bland and Altman plot of the difference ...

BACKGROUND The continuous monitoring of splanchnic organ oxygen saturation could make the early detection of inadequate tissue oxygenation feasible, reducing the risk of hypoperfusion, severe ischemia, multiple organ failure, and, ultimately, death. Current methods for assessing splanchnic perfusion have not been widely accepted for use in the clinical care environment. In an attempt to overcom...

The aim of this study was to evaluate the performance of "new-generation" pulse oximeters in extremely low-birth-weight ([ELBW] ≤ 1000 g) infants. In a prospective crossover observational study, the performance of pulse oximeters of 3 brands (Masimo, Nellcor, and Philips) was evaluated by dual SpO2 measurement in ELBW infants. Disposable probes of either equal or different brands were placed ar...

Introduction Reliable and accurate pulse oximetry requires the design and operation of the entire system to function together. Contributions ranging from the sensor technology, cabling and electronics, signal processing and alarm technologies, to communicating results to caregivers through local and remote displays, are all critical and interrelated (Figure 1). Many years of experience in each ...
