A computerized method has been developed to determine the conductance characteristics of pneumotachometers. Conductance values flowmeter, which correspond all pressure values, can be determined by a weighted averaging technique, when multiple strokes precision 3-liter calibrated syringe are used. The then allow measured differential pressures converted, point point, into flows. accuracy volumes is within +/- 0.5% for 100-stroke calibration process, and with 50 provides 1% accuracy. improves on-line measurements ventilation.
