This number is acquired using an equation that takes into account your height and weight. Schnur (1999) reviewed use of the sliding scale as a coverage criterion and reported that, while many payers had adopted it, many had also misused it.12 Schnur pointed out that if a payer used weight of resected tissue as a coverage criterion, then if the weight fell below the 5th Scale factor of length = 4 feet. This indicates an effective cardiac output. vEW 4/}8i)PcQh\:.M:+**gDgEX&a+C:tBB\%@27J8 xf8%uMPgoK9o R[D!8@b There is also evidence that BSA becomes less accurate at the extremes of height and weight, and BMI may be a better estimate in such cases.

(1991) at the request of third-party payers, developed a sliding scale.10, This scale was based on survey responses from 92 of 200 solicited plastic surgeons, who reported the height, weight, and amount of breast tissue removed Calculated based on height and weight, 1 BMI is easy to measure, reliable, and correlated with percentage of body fat mass. It determines the dose of chemotherapy for a patient. The Appel scale was the most accurate ( r2 = 0.642; b1 = 1.01; p < 0.001), followed by the Descamps ( r2 = 0.572, b1 = 0.934, p < 0.001) and Galveston ( r2 = 0.672; b 1 = 0.654; p < 0.001) scales.
