Stun Guns – How They Disrupt The Human Body’s Electrical Signals
A stun gun is a self defense product that emits an electrical charge to take down an attacker. Most models have anywhere from two to four metal contacts that .38 special ammo , when touched against someone, will send electricity into the body. The ensuing electrical charge affects the central nervous system and will incapacitate him. But how does it work and how much damage can it cause? In order to answer these questions we must first explore the basic concepts of electricity and how it works in the body.
Many people think that the shock from a stun gun can cause serious injury or death. Although it is true that exposure to electricity can cause severe organ damage and even death, this is not true of stun guns. If an electrical charge is high in amps it can lead to death, but a high voltage will do nothing more than cause pain. Think of voltage as pressure or intensity and amperage as speed. The human body can take a lot of electrical “pressure” (voltage) at a low current or “speed” (amperage). The higher the speed, the more likely that serious damage will occur. A typical stun gun may contain a charge of up to a million volts, but less than 5 milliamps. So a stun gun sends an electrical charge at a great intensity into the human body but does so at a minuscule speed.
The following table gives examples of amperage and the effect on the human body;
1 milliamp – Tingling Sensation in the muscles.
3 – 5 milliamps – Muscle contractions, moderate pain, loss of balance and disorientation.
6 – 15 milliamps – Painful, but voluntary muscle control still maintained.
100 – 200 milliamps – Extreme pain, Ventricular fibrillation (uneven, uncoordinated pumping of the heart.) Muscular contraction and nerve damage begins to occur. Death is likely.
Stun guns used by police have been erroneously blamed for numerous deaths in recent years. However, investigations have shown that the deaths were caused by outside influences and not the stun gun. Most of the individuals who died after contact with a stun gun were under the influence of mind-altering drugs like cocaine. According to research, the presence of cocaine in the bloodstream increases the “shock” from a stun gun by 50 to 100 percent.
