How do you read a West nomogram?
One method method is using the West Nomogram. Using a straight edge (such as a ruler or piece of paper), align the straight edge so it intersects at the child’s height and weight….
| BSA | x adult dose = approx. child dose |
|---|---|
| 1.73 |
What is West nomogram?
WEST NOMOGRAM: ESTIMATING BODY SURFACE. AREA OF INFANTS AND YOUNG CHILDREN. To determine a child’s body surface area, draw a straight line between the child’s height and weight. Body surface area in square meters is shown by the point where the line crosses the surface area scale.
What is a normal BMI and BSA?
For a distribution of BM/BSA values comparable to the distribution of normal BMI values, the range 35.5-39.9 kg/m2 is chosen as normal, although it covers BM range 50 to 90 kg. The proposed normal BM/BSA range suggests that heavy adults with less than 2 m of height are not obese only if they are less than 90 kg.
How do you calculate BSA for a child?
We retrospectively compared body surface area (BSA) using the Mosteller formula square root(H x (w/360)) and a simple weight-based BSA formula ([4Wkg+7]/ [90+Wkg]).
What does a nomogram measure?
nomogram, also called nomograph, calculating chart with scales that contain values of three or more mathematical variables, widely used in medicine, engineering, industry, and the biological and physical sciences. Related Topics: machine calculation.
What is a good BSA score?
Average body surface area for adult men: 1.9 m2. Average body surface area for adult women: 1.6 m2. Average body surface area for children (9 years): 1.07 m2.
What is BSA formula?
According to Mosteller’s “simplified calculation of body-surface area In metric terms” the body surface area = the square root of product of the weight in kg times the height in cm divided by 3600.
Are nomograms accurate?
Results from a nomogram are obtained very quickly and reliably by simply drawing one or more lines. The user does not have to know how to solve algebraic equations, look up data in tables, use a slide rule, or substitute numbers into equations to obtain results.
Why do we use a nomogram?
Why Are Nomograms Important to Research Design? Nomograms provide an improved ability to identify the correct patient population for clinical studies. The statistical power in prospective studies with dichotomous clinical outcomes is derived from the number of events.
