Abstract
A non-airtight method for determining alveolar ventilation, oxygen uptake and carbon dioxide production which comprises introducing a known amount of an inert gas into the airway of a patient during inspiration and monitoring the expired gas until a steady state is reached wherein the volume of inert gas inhaled is equal to the amount exhaled and subsequently monitoring the expired air containing a known volume of inert gas for inert gas, carbon dioxide and oxygen concentrations.
