Calibration of a Floscope peak flow meter and a Vitalography pulmonary monitor.
The performance of a Floscope peak flow meter and the Vitalography pulmonary monitor are assessed using an absolute calibration method. Both instruments have good repeatability. For peak flows greater than 150 litres/minute, the Floscope showed errors of between - 12.4% and +7.1%. For flows below 150 litres/minute the percentage errors were greater. The pulmonary monitor showed errors of between - 20% and 5.5%. Its high resistance makes it an inappropriate instrument to use for absolute measurement of peak flows. It is useful for assessing trends.
