What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Ventilatory threshold. It is commonly used with the system or sample type ^Patient.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Both

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

Ventilatory threshold [Volume Rate Content]
Ventilatory threshold
The ventilatory threshold (VT) is the intensity of exercise at which the production of carbon dioxide and consequent increase in ventilation, both of which are related to the production of lactate during exercise, become disproportionately higher than oxygen consumption (VO2). The VT usually occurs at about 60-70% of maximum oxygen consumption. Both VT and maximum VO2 are predictors of mortality in patients with congestive heart failure. [PMID21977155] The specific method used to calculate the VT should be reported along with the result.
