Abstract
A device for collecting alveolar breath. Breath is expired into the inlet of a hollow body. The hollow body has two outlets, with a valve disposed in each outlet. The concentration of a specific gaseous component of expired breath is monitored by a gas concentration monitor as the expired breath passes through the hollow body to determine when alveolar breath is present in the hollow body. When alveolar breath is present in the hollow body, the valve in the second outlet is actuated to an open position to collect the alveolar breath in the collection reservoir affixed to the hollow body at the second outlet.
