Effect of Alveolar Minute Ventilation on Respiratory Gas Heat Content

Completed

Conditions studied: Ventilation Perfusion Mismatch

In brief

This is a single site, prospective, non-blinded, non-randomized, non-interventional study designed to evaluate the effect of changes in alveolar minute ventilation on the measurement of respiratory heat loss (enthalpy).
