The Average Tax Rate Definition. The average tax rate in the United States varies depending on the amount of income to which it's applied. An average tax rate as it applies to income tax may be defined as the percentage of income owed as taxes or, as Fair Tax defines the term, as the ratio of taxes paid to taxable income. In mathematical terms, divide the total tax liability by total taxable income to get the average tax rate.
Escharotomy is the surgical division of the nonviable eschar, which allows the cutaneous envelope to become more compliant. Hence, the underlying tissues have an increased available volume to expand into, preventing further tissue injury or functional compromise (see image below).
An eschar (/ËÉskÉr/ ; Greek: eschara) is a slough or piece of dead tissue that is cast off from the surface of the skin, particularly after a burn injury, but also seen in gangrene, ulcer, fungal infections, necrotizing spider bite wounds, and exposure to cutaneous anthrax.schar is sometimes called a black wound because the wound is covered with thick, dry, black necrotic tissue. Eschar may be allowed to slough off naturally, or it may require surgical removal (debridement) to prevent infection, especially in immunocompromised patients (e.g. if a skin graft is to be conducted).
