Time-pulse generator for flow-volume curves.
Hankinson JL; Lapp NL
J Appl Physiol 1970 Feb; 29(1):109-110
A relatively simple, inexpensive time pulse generator for super imposing accurately timed pulses onto the flow-volume curve of a forced vital capacity (FVC) maneuver is described. The generator can be incorporated into a system that provides a fast, accurate method of obtaining flow-volume curves and the timed forced expiratory volumes in the field.
