Abstract

A microprocessor for pulmonary function testing is described. The system employs a KIM-1 microprocessor, with 2K read-only memory and 1K random-access memory, a Datel 12 bit A/D converter and power supply. The system is programmed on a linear basis, and displays standard pulmonary function values and ratios of ATPS BTPS.
