Computerized Determination of Lungfunction Parameters
In the Departments Allergology and Lungfunction of the Internal Clinic of the Groningen University Hospital the routine spirometric measurements to determine lungfunction parameters have been computerized. These routine measurements consist of the determination of the inspiratory Vital Capacity (VC) and the one second Forced Expiratory Volume (FEV or FEV1). The measurements are performed by means of a Spirometer connected to a dedicated, on line, real time minicomputersystem (PDP-8/E). Both departments run their own program at the same time in the same computer. The Lungfunction program can only service one spirometer and assists the lungfunction technician by a heavy graphical feedback from the computer and consequently has the highest priority. The Allergology program can service up to five spirometers simultaneously. This multiple of spirometers is necessary because of the time dependency of the lungfunction parameters is determined during and/or after the administration of an increasing amount of a drug which gives a long occupation of each spirometer.
