Abstract
Apparatus for measuring expired gas concentration in infants whose breathing rate is too high for normal analyzers by sampling the breath, for instance from the tube between the respirator and the infant, and drawing that sample of gas into an elongated, small diameter tube which serves to store the sample in a linear array substantially without intermixing. Several breaths are thus stored after which time the sampling may be interrupted and the stored gas drawn slowly through a gas analyzer.
