Investigators used a Masimo Radical-7 rainbow SET Pulse CO-Oximeter, which automatically calculated and displayed PVI, and a minimally invasive esophageal Doppler monitor (CardioQ-ODM, Deltex Medical).
1 In addition, new evidence from a London Ambulance Service pre-hospital CO screening study shows that using the Masimo Rainbow SET Rad-57 Pulse CO-Oximeter significantly improved detection of CO poisoning at an earlier stage, while reducing unnecessary hospital transports and patients entering the Accidents & Emergency system.
On the ABL 725, 1 [micro]L of blood is ultrasonically hemolyzed in the co-oximeter, and a continuous spectrum derived from 128 wavelengths between 478 and 672 run is used to calculate the Hb concentration in the sample (4).
1 and March 31, 2011, researchers Nilay Zorbalar, Murat Yesilaras, and Ersin Aksay at Izmir Tepecik Research and Educational Hospital in Izmir, Turkey, used a Masimo Rad-57 Pulse CO-Oximeter to noninvasively assess SpCO on 482 patients who complained of headaches.
During a recent comparison of two portable hemoglobinometers designed for near-patient testing, we noted disparate readings on a quality-control material derived from human hemoglobin (Level 1, Multi-4 [R] CO-Oximeter Controls; Instrumentation Laboratory).

The blood gas and CO-oximeter analyzers were an AVL Omni 9 blood gas analyzer and a CO-oximeter from AVL Scientific, and a Radiometer OSM3 hemoximeter attached to an ABL 505 blood gas analyzer from Radiometer America.
The custom-coded SHARC processor was chosen for Masimo's next generation product for its proprietary signal processing algorithms that utilize 40-bit floating-point format, which provides enhanced precision that is critical for medical devices such as the Masimo pulse CO-oximeter.
The contract also adds Masimo rainbowA SETA measurement capabilities with Masimo's handheld Rad-57 Pulse CO-Oximeter , designed to deliver rapid noninvasive blood measurements for improved patient assessments.
These measurements have been performed with a CIBA Corning 270 CO-oximeter and, at present, are also performed with a Chiron 865 blood gas analyzer equipped with a CO-oximetry module (Chiron Diagnostics NV).
11, 1995--AVL Scientific Corporation has developed a new blood gas data management system that automatically receives and stores data from a combination of up to eight blood gas, CO-oximeter and electrolyte analyzers at a time.
Masimo's Radical-7A Pulse CO-Oximeter with upgradable rainbowA technology and Masimo's handheld Rad-5A and portable Rad-8A with SET Measure-through Motion and Low Perfusion pulse oximetry will be available to MWI's U.
