Masimo, the inventor of Pulse CO-Oximetry and Measure-Through Motion and Low Perfusion pulse oximetry, has presented a new clinical study at IARS Annual Meeting in Honolulu, Hawaii. The study demonstrated that noninvasive and continuous hemoglobin (SpHb) from Rainbow SET Pulse CO-Oximetry provides comparable accuracy as point-of-care invasive measurements of total hemoglobin versus standard laboratory invasive measurements of total hemoglobin.

The study confirmed that SpHb is accurate, reliable, and a clinically-acceptable alternative for monitoring hemoglobin, and is the first SpHb study presented in pediatric patients.

Masimo said that Dr Fay Jou and colleagues at the Cincinnati Children’s Hospital Medical Center in Ohio compared SpHb and point-of-care (POC) hemoglobin measurements (Abbott iStat) to a standard laboratory hematology analyzer (Abbott Cell Dyn hematology analyzer) in 15 pediatric patients undergoing surgery. Compared to standard laboratory hemoglobin measurements, SpHb and iStat had a similar bias and standard deviation.

SpHb is available as part of Masimo Rainbow SET Pulse CO-Oximetry the technology platform to noninvasively measure blood constituents and fluid responsiveness that previously required invasive procedures, including: total hemoglobin (SpHb), oxygen content (SpOC), carboxyhemoglobin (SpCO), methemoglobin (SpMet), PVI, and acoustic respiration rate (RRa), in addition to the ‘gold standard’ Measure-Through Motion and Low Perfusion performance of Masimo SET oxyhemoglobin (SpO2), pulse rate (PR), and perfusion index (PI).

Masimo SpHb and PVI have been shown in multiple clinical studies to provide accurate, reliable, real-time measurements that help clinicians to proactively monitor and manage hemoglobin and fluid volume levels more appropriately and optimally.

Dean Kurth, anesthesiologist in chief at Cincinnati Children’s Hospital Medical Center, said: “The study results indicate that Masimo SpHb has the potential to replace the need for invasive blood draws in infants and children undergoing surgery.”
