  • Title: Fire death and hypoxic death.
    Author: Yamamoto K.
    Journal: Nihon Hoigaku Zasshi; 1992 Dec; 46(6):389-92. PubMed ID: 1303436.
    Abstract:
    Participation of hypoxic hypoxia in low COHb (Carboxyhemoglobin) concentrations frequently observed in fire victims was examined using rats and rabbits exposed to low-O2 and CO gas mixtures. Rats exposed to the most hypoxic gas mixture (O2 3%-CO 0.3%) died with COHb value below 40%. Rabbits also died with a low COHb concentration under this condition, but the COHb concentration was not below 50%. From the literature as well as the findings obtained in the present experiment, hypoxic hypoxia did not appear to be a main factor causing death at low COHb concentrations.
