Two sets of standardized waveforms that are used to test spirometry software. The first set (24 files) was created by John Hankinson at NIOSH in Morgantown, WV. The data is in liters at 10 msec intervals (i.e. 100 hz) and the second set (26 files) contain flows (L/sec), at 0.002 second (500 hz) sampling intervals. Since the files consist solely of volume data points, flow is synthesized by calculating the difference between adjacent volumes and dividing by the difference in time.
