Carbon monoxide poisoning: carboxyhemoglobin
can be measured with standard blood tests [letter].
By reviewing the carboxyhemoglobin
level, the timing of the sample, and the extent of treatment, a toxicologist may provide useful evidence of the potential ranges of exposure times and concentration levels.
report a fatality case in which postmortem measurement of carboxyhemoglobin
was key evidence in a criminal prosecution.
As Table 1 shows, the effects of carboxyhemoglobin
on the HemoCue were inconsistent and seemed to depend on the initial percentage of HbCO.
So, when patients had elevated carboxyhemoglobin
(from carbon monoxide poisoning) and/or elevated methemoglobin (negative reaction to more than 30 common drugs used in hospitals, like caines, nitrates, and Dapsone), the displayed functional oxygen saturation overestimated the actual oxygen saturation value.
They come in three sizes: 115mL, 150mL, and 230mL, and are available with either sodium or balanced heparin for accurate testing of pH, blood gases, electrolytes, carboxyhemoglobin
, and other analytes.
The measurements of the carboxyhemoglobin
fraction made by seven of the eight test instruments are shown in Fig.
Parameters in use include total hemoglobin (SpHb), oxygen content (SpOC (TM)), carboxyhemoglobin
(SpCO), methemoglobin (SpMet), and Pleth Variability Index (PVI), in addition to the Measure-Through Motion and Low Perfusion performance of Masimo SET oxyhemoglobin (SpO[sub.
Parameters in use include total hemoglobin (SpHbA), oxygen content (SpOC ), carboxyhemoglobin
(SpCOA), methemoglobin (SpMetA), and Pleth Variability Index (PVIA), in addition to the Measure-Through Motion and Low Perfusion performance of Masimo SETA oxyhemoglobin (SpO2), perfusion index (PI), and pulse rate (PR).
The Chiron 800 CO-oximeter is an overdetermined system that uses 10 wavelengths to directly measure total hemoglobin, oxyhemoglobin, carboxyhemoglobin
, deoxyhemoglobin, and MetHb.
Today, the health system is expanding its relationship with Masimo and deploying two new Masimo rainbowA SETA Pulse CO-Oximetry measurements: carboxyhemoglobin
(SpCOA) and methemoglobin (SpMetA), which help clinicians measure and detect carbon monoxide and methemoglobin blood levels without a painful needle stick or time-consuming blood lab analysis.
