How do you measure your arm mass?

Formulas

1. Upper arm muscle circumference (S) in mm: S = c – ( T * 3.14)
2. Upper arm area (A) in mm² : A = c² / 12.56.
3. Upper arm muscle area (M) in mm² : M = S² / 12.56.
4. Upper arm fat area (F) in mm² : F = A – M.

How do you do MUAC weight?

Measuring mid upper arm circumference (MUAC) Measure the distance between the 2 points, identify the mid point and mark on the arm. Ask subject to let arm hang loose and with tape measure, measure circumference of arm at the mid point. Do not pull the tape measure tight – it should just fit comfortably round the arm.

What is MUAC measurement?

Mid-upper arm circumference, often shortened to MUAC, is a measurement that allows health workers to quickly determine if a patient is acutely malnourished. PIH, as well as many other organizations, measures the circumference of a patient’s arm at the midpoint between his or her shoulder and elbow.

How do you calculate mid upper arm circumference?

To measure:

1. Bend the left arm, find and mark with a pen the olecranon process and acromium.
2. Mark the mid-point between these two marks.
3. With the arm hanging straight down, wrap a MUAC tape around the arm at the midpoint mark.
4. Measure to the nearest 1 mm.

How do you convert arm weight to circumference?

Derivation and validation of a novel method to estimate weight in adults and adolescents, using mid-arm circumference (MAC). Weight (in kg) = 4 x [MAC (in cm)] – 50.

What is the average circumference of a woman arm?

So, how do Americans’ arms measure up? In the 1960-1962 report, men had an average mid-arm circumference of 12.1 inches (30.7 cm); for women, the average measurement was 11.2 inches (28.4 cm).

What age is MUAC?

MUAC is a quick and simple way to determine whether or not a child is malnourished using a simple colored plastic strip. MUAC is suitable to use on children from the age of 12 months up to the age of 59 months. However, it can also be used for children over six months with length above 65 cm.

How does hospice measure mid arm circumference?

Locate the olecranon process, the tip of the elbow. Locate the acromial process, the tip of the shoulder. Measure on the posterior aspect of the arm between these two points, being careful to keep the tape straight. Divide the length by 2 and mark this midpoint on the arm with a pen.
