Abstract :
An instrument which measures maximally forced expiratory airflow directly, computes its integral (lung volume decrement ), and interrupts the storage oscilloscope display of this flow-volume trajectory at fixed but adjustable intervals of time is described. This new device is portable and does not involve bellows or a water-filled canister.
