Carbon dioxide end tidal baseline - sub-maximal exercise delta   96976-6

LOINC Code


LOINC code96976-6
nameCarbon dioxide end tidal baseline - sub-maximal exercise delta
descriptionEvaluating the difference between end tidal carbon dioxide (ET CO2) levels before and after submaximal exercise can distinguish healthy patients from those with pulmonary arterial hypertension (PAH), as well as determine the severity of PAH. [PMID: 21622009]
statusACTIVE

Fully-Specified Name

componentCarbon dioxide^at end expiration-Carbon dioxide^at end expiration+W sub-maximal exercise
propertyPPresDiff  =  Difference in Partial Pressure
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.
systemExhl gas  =  Exhaled gas (breath)
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
