The need for performance control of spirometers has been studied in Helsinki hospitals. The performance of 27 instruments was measured using 11 technical test parameters. The performance was assessed by calculating figures of merit (FM) determined as a weighted sum of the test results. 55% of the devices failed the test. Performance was specific for each instrument, was dependent on maintenance but independent of instrument age. Specific attention to accuracy is recommended in measuring rapid forced expiratory parameters with wedge-type volume meters sealed with bellows. Although daily calibration is helpful, it is not sufficient to maintain optimal performance. Device maintenance should start from acceptance trials to detect manufacturing problems and be complemented by periodic technical performance tests.
