Carboxyhemoglobin (SpCO^®) is part of Masimo Rainbow SET^®, a noninvasive blood constituent monitoring platform that provides measurements that previously required invasive blood sampling and time-consuming laboratory analysis.

When used with other clinical variables, SpCO may help clinicians assess carbon monoxide poisoning status and help determine treatment and additional test options.

• > Exposure to carbon monoxide (CO) is the leading cause of death by poisoning in industrialized countries¹
• > CO poisoning is often misdiagnosed because symptoms are similar to the flu²
• > Timely diagnosis and treatment of CO poisoning is critical³
• > SpCO has been shown to identify 60% more carbon monoxide poisonings than traditional methods⁴
• > SpCO may improve patient outcomes, increase clinical efficiency, and decrease the cost of care

"Carboxyhemoglobin measurements performed noninvasively in the Emergency Department with Masimo Pulse CO-Oximetry should lead to enhanced diagnosis of CO poisoning, increased referral for appropriate treatment, and a resultant reduction in morbidity from the disease."
