TABLE 1963 Levels of Electrical Exposure

Contact with electrical current causes injury through thermal heating, induced muscle contraction, thermal burns, and blunt trauma (IableJ.96-4). Direct tissue heating, predicted by Joule's law, has been generally implicated as the direct etiology of tissue damage from electricity, although that concept has been challenged when contact time is brief.4 Regardless, current intensity is the most critical determinant of tissue damage, but from a practical standpoint, while voltage is frequently known in an electrical exposure, current is not. Ihus, voltage is usually used as a proxy for current in predicting the potential damage from an electrical shock.

Blood Pressure Health

Your heart pumps blood throughout your body using a network of tubing called arteries and capillaries which return the blood back to your heart via your veins. Blood pressure is the force of the blood pushing against the walls of your arteries as your heart beats.Learn more...
