6] These data have previously led to suggestions that SpCO could be used as a tool to help determine whether an invasive blood measurement of carboxyhemoglobin (COHb) should be performed to confirm CO intoxication.
In 2005, Masimo introduced rainbow SET Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously required invasive procedures, including total hemoglobin (SpHb), oxygen content (SpOC (TM)), carboxyhemoglobin (SpCO), methemoglobin (SpMet), and Pleth Variability Index (PVI), in addition to SpO2, pulse rate, and perfusion index (PI).
The crucial factors affecting diffusion are hemoglobin, carboxyhemoglobin, cardiac output and lung inflation.
With a cutoff of 6% and higher for carboxyhemoglobin, the sensitivity was 46% and the specificity was 94% to detect a smoker, with a positive predictive value of 67% and a negative predictive value of 87%, said Dr.
All presenting patients should have laboratory samples drawn, beginning with either an arterial or venous blood gas to determine the carboxyhemoglobin (COHb) level, (12) although the COHb numerical value in itself does not necessarily correlate clinically.
Obtaining carboxyhemoglobin blood level results can help to diagnose carbon monoxide exposure, but a clinical evaluation of the victim's symptoms is also essential.
PVI is available as part of Masimo rainbow[R] SET platformthe first-and-only technology to noninvasively and continuously measure total hemoglobin (SpHb[R]), oxygen content (SpOC), carboxyhemoglobin (SpCO[R]), methemoglobin (SpMet[R]), Pleth Variability Index (PVI[R]), perfusion index (PI), and acoustic respiration rate (RRa), in addition to the 'gold standard' Measure-Through Motion and Low Perfusion performance of Masimo SET[R] oxyhemoglobin (SpO2), and pulse rate (PR).

It continues Physio-Control's legacy of industry firsts as the first monitor/defibrillator to integrate Masimo Rainbow SET([R]) Pulse CO-Oximetry[TM] technology for the noninvasive detection of carboxyhemoglobin (carbon monoxide in the blood; the leading cause of poisoning death in industrialized countries1) and methemoglobin in the blood (which may result from exposure to certain chemicals and drugs).
Masimo announced today that a new clinical study recently published in the Emergency Medicine Journal shows that Masimo's noninvasive carboxyhemoglobin (SpCO) from rainbowA Pulse CO-Oximetry helped clinicians identify 23% more patients with carbon monoxide (CO) poisoning who presented to the emergency department (ED) with headaches.
