N2  - Most evaluations of the pathophysiological processes of suicidal hangings are based on animal experiments and only a few have examined the hanging process. The little information available is mostly the result of animal experiments that have focused on tracheal obstructions. In the study presented here, a camcorder was set up by the victim to record the entire hanging process. According to the analysis from the recording, the complete asphyxial process lasted only 2 minutes and 43 seconds. Stage 1 (the prodromal stage) was especially short. Typical convulsions were not observed in this case. Body movements, such as clonic and tonic spasms, were not noticed in stage 2 (the dyspnea stage). Because the body did not touch the ground, the pressure on the neck by the ligature caused cerebral ischemia as a result of the obstruction of the neck vessels. Consequently, it can be hypothesized that suicide by hanging may not be based on the effect of changed concentration in the blood of carbon dioxide and oxygen, but on the effect of cerebral ischemia.<p /> <p>Language: en</p>
