gas exchange index

gas ex·change in·dex

(gas eks-chānj' in'deks) Assessment tool to gauge respiration.

gas exchange index

One of several measurements of the efficiency of respiration, esp. of the extent of intrapulmonary shunting in respiratory failure. Among the commonly used gas exchange indices is the alveolar-arterial oxygen tension difference (a measurement derived from an analysis of the oxygen tension of an arterial blood gas compared with the atmospheric oxygen content).
