| description | Activity level is calculated as vector magnitude units (VMU) based on axial accelerations in all three dimensions and is reported in gravity (g) units. This term was created for, but is not limited in use to, the Zephyr BioHarness, a physiological monitoring belt device that captures and transmits multiple physiologic parameters. | ||

| component | Activity level | ||
| property | Accel = Acceleration | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | ^Patient | ||
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | ||

| formula (readable) | Activity level = Vector magnitude units (VMU) = SUM[SQR RT(x^2+y^2+z^2)] for each 1 second time epoch/number of time epochs, where x, y and z are the axial accelerations in each individual dimension. | ||
| example UCUM units | g units The Unified Code for Units of Measure (UCUM) is a code system intended to include all units of measures being contemporarily used in international science, engineering, and business (www.unitsofmeasure.org) | ||
