Automated Pulmonary Analysis by an Online Microcomputer
A general purpose microcomputer based data acquisition system (Digital Equipment Corporation, DECLAB MINC 11/03) has been installed at the National Institutes of Health to facilitate automation of both standard and experimental pulmonary testing procedures. Whereas commercial pulmonary systems have been generally suitable for routine pulmonary function tests (PFT’s)1, it has been necessary to manually perform more involved procedures such as compliance, work of breathing and exercise testing: Commercial systems are slowly becoming available which perform exercise testing; however, they do not provide a simple means for the user to add new procedures or modify existing protocol as is required in a dual clinical/research environment like that at the NIH. Additionally, a means for data archiving is desirable.
