Using ndd Medical Technologies’ EasyOne spirometer, COPD patients enrolled in the WISDOM (Withdrawal of Inhaled Steroids During Optimized Bronchodilator Management) study were as adept in monitoring lung function at home as the professionals who performed their baseline measurements in the clinic when the trial began.
Results of the 2,161-patient clinical trial were presented in a poster at this year’s American Thoracic Society meeting in Denver. Most patients in the study had severe or very severe COPD.
“Home-based monitoring of lung function in patients with COPD may provide detailed insights into the course of disease and variations in lung function between clinical visits,” the investigators commented.
The EasyOne spirometers used in the WISDOM and other clinical trials are portable spirometers employing advanced TrueFlow ultrasonic technology. There are no moving parts, no codes to enter, no screens to catch sputum, and no disposables to calibrate. The ultrasonic flow measurement is independent of gas composition, pressure, temperature, and humidity thus eliminating errors due to these variables.
