Use of CO Oximeters (CO-oxi) in Diagnosis of Carbon Monoxide Poisoning
Group: Tori Costello, Tim Cox, Marissa Davis, Brooke Dean, & AJ Heaps
CO poisoning is a problem that can result in a health emergency that doctors must be able to diagnose accurately and efficiently. Regular pulse oximeters do not accurately differentiate between oxyhemoglobin and carboxyhemoglobin due to the similarities in wavelength and molecular size. Therefore a patient suffering from CO poisoning may have a seemingly normal O2 saturation. In a study with 12 healthy, non-smoking, adult volunteers, researchers found that the Radical 7 CO Oximeter could accurately detect hypoxemia and carboxyhemoglobin levels but could not accurately read SpCO when arteriole O2 saturation was less than 85%. This technology will likely be extremely beneficial in the identification and diagnosis of patients with CO poisoning.
