Fire death and hypoxic death

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.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...

Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

Hypoxia
Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...
Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
