Investigation of oxyhemoglobin and carboxyhemoglobin ratios in right and left cardiac blood for diagnosis of fatal hypothermia and death by fire

Investigation of oxyhemoglobin and carboxyhemoglobin ratios in right and left cardiac blood for diagnosis of fatal hypothermia and death by fire

Highlights • High laterality of %O2 -Hb is an important evidence when diagnosing fatal hypothermia. • CPR does not influence the laterality of %O2 -Hb in cardiac blood. • Postmortem cooling does not appear to influence %O2 -Hb in cardiac blood. • The difference in %CO-Hb between light and heavy smok...

Zusammenfassung:Highlights • High laterality of %O2 -Hb is an important evidence when diagnosing fatal hypothermia. • CPR does not influence the laterality of %O2 -Hb in cardiac blood. • Postmortem cooling does not appear to influence %O2 -Hb in cardiac blood. • The difference in %CO-Hb between light and heavy smokers is not significant. • %CO-Hb of >10% is an antemortem CO inhalation marker regardless of smoking history.
