Accident or arson: is CO-oximetry reliable for carboxyhemoglobin measurement postmortem?
A 46-year-old woman was found dead in the basement of her home after a fire. External examination of the body showed a wound to the head and soot in the nose and mouth, with soot also found internally in the trachea and bronchi upon autopsy. On questioning by the police, the woman’s husband admitted that he and his wife were having an argument that led to him accidentally knocking her unconscio...
متن کاملPostmortem CO - oximetry
The focus of this article is the application of CO-oximetry in the analysis of blood samples after death. This is largely confined to confirming or excluding carbon monoxide poisoning as a contributory or prime cause of death, by measurement of COHb. Issues addressed will include: the toxicity of carbon monoxide; the causes of lethal carbon monoxide poisoning; and the particular difficulties su...
متن کاملPulse carboxyhemoglobin-oximetry and cigarette smoking.
PURPOSE We used a pulse carbon monoxide (CO)-oximeter to measure the levels of carboxyhemoglobin (COHb) in smokers and non-smokers. Our goal was to determine if this device could not only define smoking status, but also to increase accuracy of self-reported data at various surveys on smoking. METHODS Thirty-four healthy volunteers participated in this study. Twenty-two of them were current da...
متن کاملIs Quantitative HBsAg Measurement a Reliable Substitute for HBV DNA Quantitation?
Background: Hepatitis B surface antigen (HBsAg) is one of the main proteins of HBV envelop and its serum quantitative measurement is the most common quantitative test for monitoring the progress of Chronic Hepatitis B. Although measurement of serum HBV DNA copy number is a gold standard method for displaying viral load, the test is relatively expensive and it is not readily available everywhere...
متن کاملMeasurement of carboxyhemoglobin and methemoglobin by pulse oximetry: a human volunteer study.
BACKGROUND A new eight-wavelength pulse oximeter is designed to measure methemoglobin and carboxyhemoglobin, in addition to the usual measurements of hemoglobin oxygen saturation and pulse rate. This study examines this device's ability to measure dyshemoglobins in human volunteers in whom controlled levels of methemoglobin and carboxyhemoglobin are induced. METHODS Ten volunteers breathed 50...
