LOINC code69429-9
nameMetabolic rate --resting
descriptionResting metabolic rate (RMR) is frequently estimated in clinical medicine to determine minimal energy requirements for patients receiving nutritional therapy. RMR estimates are also used to counsel patients regarding caloric intake in weight loss programs. RMR measurement by indirect calorimetry requires quantification of oxygen consumption and sometimes carbon dioxide production while a patient is resting.

componentMetabolic rate^resting
propertyEngRat  =  Power = Energy/Time
timePt  =  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
scaleQn  =  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
