How long is the duration of current - electric batons Self-defense equipment net

Self-defense electric batons current of lightning damage to human body and its role in the length of time there is a close relationship, ventricular fibrillation threshold not only has relationship with current strength, but also has a lot to do with the duration of the current, current time more long, the current of lightning damage to human body more significantly. This is caused by the following three reasons. 1, the human body in the process of electricity, due to the hot sweat and current electrolysis of human tissue, make human body resistance is reduced, which resulted in increased current. 2, the heart of the people in each contraction diastole movement cycle, there is a zero. 1 to 0. 2 s easy to quiver period, during which the heart fiber in incongruous excited state, the sensitivity to the current stimulus is the largest. When the current lasts more than one cardiac cycle, inevitably encounter with easy to quiver period, resulting in great danger. An adult heart about 70 times per minute, one cardiac cycle is zero. The 86 s, if electric batons electric shock every time more than 0 of the body. 86 s, there is a danger of ventricular fibrillation. 3, electrify time more long, the greater the current dissipation of energy in the human body, the harm of human body is stronger. The experimental results show that for electric batons, electric batons shock 0. More than 5 s can make the person jumped, muscle contraction, spasm; Continuous electric shock more than 1 s can make the person temporarily lose balance, a sense of direction, confusion, pain, loss of control. A abroad about self-defense electric batons electric batons does to the human body described in the report: & other; As long as be 0. 5 s shock you will get a big surprise and repelled by electricity; 1 ~ 2 s can make people lost the ability to stand; 3 ~ 5 s can make the person can't move, at least in a coma for five minutes, even for 15 minutes.
