An electrical injury (electric injury) or electrical shock (electric shock) is damage sustained to the skin or internal organs on direct contact with an electric current. [ 2 ] [ 3 ] The injury depends on the density of the current , tissue resistance and duration of contact. [ 4 ]
It is important to note that microshock (or micro-shock) are not IEV [2] defined terms and are not used in any international standard. "Micro-shock" is an otherwise imperceptible electric current applied directly, or in very close proximity, to the heart muscle of sufficient strength, frequency, and duration to cause disruption of normal cardiac function.
Electrical shocks on humans can lead to permanent disabilities or death. Size, frequency and duration of the electrical current affect the damage. [8] The effects from electric shock can be: stopping the heart beating properly, preventing the person from breathing, causing muscle spasms. The skin features also affect the consequences of ...
Forceful propulsion of the body, producing such injuries as spinal and limb fractures. [8] These injuries must be treated in addition to the burns themselves. In very rare instances, a high voltage electric shock can cause cataracts in the lens of the eyes, and detachment of the retina. This may be delayed for some days or weeks after the ...
The passage of current from one part of the body to another, especially from arm to arm and therefore through the heart. By this definition, the magnitude of the current itself (in amperes) is the most important factor. In general, the greater the current, the more dangerous a shock is and the more likely it is to be lethal.
"The potential dangers of using at-home LED masks include headaches, eye strain, sleep disturbances, insomnia and mild visual side effects," she explained.
The feeling of an electric shock is caused by the stimulation of nerves as the current flows through the human body. The energy stored as static electricity on an object varies depending on the size of the object and its capacitance, the voltage to which it is charged, and the dielectric constant of the surrounding medium.
