The human pathophysiology of asphyxia by hanging is still poorly understood, despite great advances in forensic science. In that context, filmed hangings may hold the key to answer questions regarding the sequence of events leading to death in human asphyxia. Four filmed hangings were analyzed. Rapid loss of consciousness was observed between 13 sec and 18 sec after onset of hanging, closely followed by convulsions (at 14-19 sec). A complex pattern of decerebration rigidity (19-21 sec in most cases), followed by a quick phase of decortication rigidity (1 min 00 sec-1 min 08 sec in most cases), an extended phase of decortication rigidity (1 min 04 sec-1 min 32 sec) and loss of muscle tone (1 min 38 sec-2 min 47 sec) was revealed. Very deep respiratory attempts started between 20 and 22 sec, the last respiratory attempt being detected between 2 min 00 sec and 2 min 04 sec. Despite differences in the types of hanging, this unique study reveals similarities that are further discussed.
尽管法医学取得了巨大进展，但绞刑导致窒息的人体病理生理学仍未得到充分理解。在这种背景下，拍摄的绞刑视频可能是解答人类窒息死亡事件顺序相关问题的关键。对四段拍摄的绞刑视频进行了分析。观察到在绞刑开始后的13秒至18秒之间意识迅速丧失，紧接着是抽搐（14 - 19秒）。呈现出一种复杂的去大脑强直模式（大多数情况下为19 - 21秒），随后是快速的去皮层强直阶段（大多数情况下为1分00秒 - 1分08秒）、延长的去皮层强直阶段（1分04秒 - 1分32秒）以及肌张力丧失（1分38秒 - 2分47秒）。在20至22秒之间开始出现非常强烈的呼吸尝试，最后一次呼吸尝试在2分00秒至2分04秒之间被检测到。尽管绞刑类型存在差异，但这项独特的研究揭示了一些相似之处，并将进一步展开讨论。
