Noninvasive Carbon Monoxide (CO) Screening with Masimo Pulse CO-Oximetry(TM) Helps Detect and Treat Victims While Identifying Source of CO Poisoning
IRVINE, Calif., Jan. 5 /PRNewswire-FirstCall/ — Masimo (Nasdaq: MASI), the inventor of Pulse CO-Oximetry(TM) and Measure-Through Motion and Low Perfusion pulse oximetry, today announced that a new case study, published in the January-March 2010 issue of Prehospital Emergency Care, showed that noninvasive screening with Masimo carboxyhemoglobin (SpCO) provided emergency first responders with immediate and accurate detection of CO-poisoned employees and enabled the identification of the source of the poisoning at a manufacturing plant. The early detection and subsequent identification of the CO source helped avert a potential disaster that may have injured or cost the lives of numerous employees and overwhelmed both the local emergency medical services (EMS) system and area hospitals.(1)
Carbon monoxide is a colorless, odorless, and tasteless toxic gas that is extremely difficult to detect–making it the leading cause of poisoning in industrialized countries. Prior to Masimo Rainbow SET Pulse CO-Oximetry, an invasive blood draw followed by laboratory blood gas analysis was the only reliable method for diagnosing CO poisoning. Without immediate access to measure CO in the blood, emergency first responders were at a critical disadvantage. Today, the portable, handheld Masimo Rad-57 Pulse CO-Oximeter provides an accurate and noninvasive way to detect elevated CO levels in the bloodstream in just seconds–allowing emergency first responders to quickly and easily diagnose CO poisoning on-the-scene and initiate prompt, lifesaving treatment.
The published case report describes how a suburban fire department and EMS unit in Rock Springs, Georgia responded to a call for a sick employee at a local manufacturing plant. The first responders combined the use of both atmospheric CO testing and Pulse CO-Oximetry to successfully diagnose the cause of the employee’s illness and identify the source of the poisoning. Upon arrival, firefighters initially used an atmospheric gas monitor to measure the amount of CO gas circulating in the air and found that the air inside the plant contained elevated, unsafe levels of CO (between 26-70 PPM). However, firefighters searching the building were unable to identify its source. All employees working inside the plant were evacuated and screened for CO poisoning by measuring their SpCO levels using the Masimo Rad-57. Although the source of the poisoning was still unknown, firefighters promptly treated employees with elevated SpCO levels–ranging from 5-18%–on the scene with high concentration oxygen.
While the most obvious source appeared to be a recently installed industrial furnace in the foundry area, no detectable atmospheric CO levels were present anywhere in the area. Although atmospheric CO levels were highest in the assembly area, there were no CO sources in that part of the building. In a second attempt to locate the source of the poisoning, firefighters marked the locations of the employees with the highest SpCO levels on a map of the plant and found that they were all working immediately under air conditioning vents in the assembly area. After tracing the air conditioning vents, firefighters determined that exhaust from the furnace in the foundry were being drawn into a nearby intake vent for the air conditioning system.
According to the lead author of the case study, Bryan E. Bledsoe, DO, FACEP, “The measurement of SpCO levels via Pulse CO-Oximetry provided the missing link to a potentially disastrous puzzle. When initial atmospheric CO monitoring missed the mark–revealing high levels in an area where no CO source existed and the absence of CO in the area where the likely source was found–Masimo SpCO allowed emergency responders to instantly detect biological CO levels, initiate treatment of those in need, and promptly map the exposure point. This potentially saved countless lives while avoiding needless transport of large numbers of employees to area hospitals, preventing significant emergency department and EMS costs–and possibly leaving others in the community without emergency services.”
Each year, the lifesaving accounts from fire departments and EMS professionals around the world showcase the importance of the Masimo Rainbow SET Pulse CO-Oximeter to their public safety efforts–helping to save lives, limit long-term brain and heart damage, and create efficiencies and cost savings in the care and delivery of emergency medical services. Most recently, thanks to the Masimo Rainbow SET Pulse CO-Oximeter and swift emergency intervention, more than 50 motel occupants and staff in North Carolina, over 40 families in Beijing, and numerous families in Alabama, Illinois, Colorado, and Washington were saved from becoming carbon monoxide-poisoning statistics.
Masimo Executive Vice President of Medical Affairs Dr. Michael O’Reilly, stated, “Whether suspected or unsuspected, CO poisoning presents a unique challenge to firefighters and EMS personnel who need to know immediately if elevated CO levels are in the bloodstream. However, because CO levels in the air of a particular area don’t always correlate to the amount of poisoning in the blood and vice versa, Masimo SpCO is a vital compliment to atmospheric CO monitoring to help first responders save lives, avert mass casualty incidents, and alleviate cost and care burdens on the local emergency system.”

Masimo (Nasdaq: MASI) develops innovative 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 SETÃ‚®, which virtually eliminated false alarms and increased pulse oximetry’s ability to detect life-threatening events. More than 100 independent and objective studies demonstrate Masimo SET provides the most reliable SpO2 and pulse rate measurements even under the most challenging clinical conditions, including patient motion and low peripheral perfusion. In 2005, Masimo introduced Masimo Rainbow SETÃ‚® Pulse CO-Oximetry(TM), a breakthrough noninvasive blood constituent monitoring platform that can measure many blood constituents that previously required invasive procedures. Masimo Rainbow SET continuously and noninvasively measures total hemoglobin (SpHb(TM)), oxygen content (SpOC(TM)), carboxyhemoglobin (SpCOÃ‚®), methemoglobin (SpMetÃ‚®), PVIÃ‚®, and acoustic respiration rate (RRa(TM)), in addition to oxyhemoglobin (SpO2), pulse rate (PR), and perfusion index (PI), allowing early detection and treatment of potentially life-threatening conditions. Founded in 1989, Masimo has the mission of “Improving Patient Outcomes and Reducing Cost of Care by Taking Noninvasive Monitoring to New Sites and Applications.” Additional information about Masimo and its products may be found at www.masimo.com.
