OBJECTIVE This study tested the effects of low perfusion caused by emerging sepsis on the reliability of a new pulse oximetry technology (Masimo SET; IVY 405T) compared with a standard pulse oximeter (Nellcor N-200). DESIGN Randomized trial. SETTING University animal research facility. SUBJECTS Twenty-six anesthetized, ventilated (Fio, 1.0), adult rabbits. INTERVENTIONS Pneumonia/sepsis...

Introduction: Fingertip pulse oximeters are commonly used as non-invasive modes of measuring oxygen saturation (SpO2) and heart rate (HR) in critical care units. In these cases, a shorter duration of time required obtaining the measurement and time to stabilization is crucial. Objective: Our aim was to compare two new generation pulse oximeters with respect to latency in the fi rst reading and ...

Objective: The purpose of this study was to derive a respiratory movement signal from 3D time-of-flight camera and investigate if it can be used in combination with SpO 2 detect events comparable polysomnography (PSG) based detection. xmlns:...

BACKGROUND Pulse oximetry is routinely used to continuously and noninvasively monitor arterial oxygen saturation (SaO2) in critically ill patients. Although pulse oximeter oxygen saturation (SpO2) has been studied in several patient populations, including the critically ill, its accuracy has never been studied in emergency department (ED) patients with severe sepsis and septic shock. Sepsis res...

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 ...

To compare pulse oximetry measurement bias between infants with hypoxemia with either dark skin or light skin with Masimo Radical 7 and Nellcor Oximax. There was no significant difference in systematic bias based on skin pigment for either oximeter.

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 ...
