TOKYO, JAPAN — (Marketwired) — Masimo announced that a new clinical study published in the Journal of Clinical Monitoring evaluated the relative trending accuracy of Masimo’s noninvasive and continuous total hemoglobin (SpHb®) in patients with end-stage renal disease who underwent dialysis.1
Dr. Hiroshi Yamada, M.D., and colleagues at Fujisawa City Hospital in Fujisawa, Japan, assessed the relative trending accuracy of SpHb using a Masimo Radical-7® Pulse CO-Oximeter (ReSposable R2 25 Sensor, Rev. F) compared to in-line monitoring of hematocrit (Crit-Line) in end-stage renal disease patients undergoing dialysis. The researchers noted that while the Crit-Line device has proven to be clinically helpful, the high cost and low availability of the Crit-Line device has compelled clinicians to seek other options to assess changes in blood volume (âˆ†BV).
In the study, researchers determined the âˆ†BV estimated by each method by calculating the change between the initial reading of the modality and the current value at the time of recording. A total of 95 data points from 12 patients over 20 dialysis sessions were analyzed. The regression correlation of changes in SpHb vs. changes in hematocrit from Crit-Line was 0.83 (P≤ 0.001).
Researchers noted, “Pulse CO-Oximetry measures âˆ†BV from SpHb as reliably as Crit-Line,” adding that, “SpHb by the pulse CO-Oximeter has good relative trending accuracy.”
SpHb is available with Masimo’s rainbow® SET® monitoring platform, enabling the noninvasive assessment of multiple blood constituents and physiologic parameters that previously required invasive or complicated procedures, in addition to providing Masimo SET® Measure-through Motion and Low Perfusion™ pulse oximetry. The rainbow® SET® platform — including RRa®, SpCO® and SpMet® — offers a breakthrough in patient safety by helping clinicians detect life-threatening conditions and helping guide treatment options.

Masimo (NASDAQ: MASI) is the global leader in innovative noninvasive monitoring technologies that significantly improve patient care-helping solve “unsolvable” problems. In 1995, the company debuted Measure-Through Motion and Low Perfusion pulse oximetry, known as Masimo SET®, which virtually eliminated false alarms and increased pulse oximetry’s ability to detect life-threatening events. More than 100 independent and objective studies have shown that Masimo SET® outperforms other pulse oximetry technologies, even under the most challenging clinical conditions, including patient motion and low peripheral perfusion. In 2005, Masimo introduced rainbow Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously could only be measured invasively, including total hemoglobin (SpHb®), oxygen content (SpOC™), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), and Pleth Variability Index (PVI®), in addition to SpO2, pulse rate, and perfusion index (PI).
