A method is described for recording alveolar CO 2 tension using simple and inexpensive apparatus. The changing state of hyperventilation due to CO 2 has been studied and a procedure devised for deriving the steady‐state CO 2 ‐response line from data obtained during the changing state. This procedure has considerable practical advantages over conventional methods. Evidence is presented to show that the time needed for equilibration of CO 2 between the arterial blood and the cells of the respiratory centre is of the order of 4 min.
