Expired minute volume/Carbon dioxide production during exercise   94119-5

LOINC Code


LOINC code94119-5
nameExpired minute volume/Carbon dioxide production during exercise
descriptionThe ventilatory efficiency slope is calculated as the ratio of minute ventilation to carbon dioxide production. It is a proxy for peak oxygen consumption and is correlated with disease severity for various cardiopulmonary conditions, including pediatric pulmonary hypertension and adult heart failure.

componentVolume.expired per minute/Carbon dioxide production^W exercise
propertyVRto  =  Volume Ratio
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
