- n. The compound that is formed when inhaled carbon monoxide combines with hemoglobin, binding more tightly than oxygen and rendering the hemoglobin incapable of transporting oxygen.
“S. O'BRIEN: Yes, he seemed to say that that was reversing, that -- what he called the carboxyhemoglobin, I guess the measure of the carbon monoxide in the blood.”
“A carboxyhemoglobin level confirmed his suspicions.”
“Acute effects are due to the formation of carboxyhemoglobin in the blood, which inhibits oxygen intake.”
“ROBERTS: Commonly done with high levels of carboxyhemoglobin or carbon monoxide.”
“It wasn't a significant amount of carboxyhemoglobin.”
“So you really have to be able to run the blood and check for carboxyhemoglobin.”
“And so unless you can detect their carboxyhemoglobin levels -- and when you put the sat -- the oxygen saturation monitor on their finger, it's false.”
“Still, it's important to remember that, whatever readout these CO-oximeters show, the level of carboxyhemoglobin does not always correlate with severity of symptoms or neuropsychiatric sequelae.”
“And, just like the pulse-ox's SpO2 readout is just a proxy for oxyhemoglobin content, an output of carboxyhemoglobin in grams per dL is more reproducible and medically significant than a percentage full disclosure: I've worked with one of these authors, he's the same one who punctured the myth that nail polish tarnishes pulse oximetry readings.”
“Masimo Rainbow SET noninvasive measurements-including: total hemoglobin (SpHb ™), oxygen content (SpOC ™), carboxyhemoglobin”
