It uses patented digital ultrasonic flow measurement technology for fast, accurate and reliable operation. The NDD EasyOne is designed for a wide range of testing in primary care, specialty physician, industrial and hospital settings. The NDD EasyOne offers automated comparison to predicted values, pre and post bronchodilator comparisons, and test quality control that automatically assesses quality control that automatically assesses patient effort and displays easy to understand messages that aid in patient coaching. The graphic display shows curves, and the optional color printout is easy to read and interpret. The single-patient-use breathing tube minimizes risk of cross-infection.
The NDD EasyOne Spirometer incorporates an ultrasonic flow sensor to measure the flow of air in and out of the patients lungs.
Ultrasonic flow measurement eliminates problems associated with traditional methods of flow measurement and helps make the NDD EasyOne spirometer extraordinarily fast, reliable, accurate, and mistake proof. There are no moving parts, no codes to enter, no screens to catch sputum, and no disposables to calibrate. Ultrasonic flow measurement is independent of gas composition, pressure, temperature, and humidity; and disqualifies mistakes due to these variables.
Transistors located on the mouthpiece cavity transmit and accept sound in alternating directions. When gas flow is existent in the tube, a pulsation that moves against the flow is slowed down and takes a longer time to reach the opposite transducer. Conversely, a pulse traveling with the flow (traveling downstream) is sped up and takes a shorter time to reach the opposite transducer.
The sound waves travel time is precisely measured with a digital clock. The gas flow through the mouthpiece is then calculated from flow times. This calculation is independent of gas composition, pressure, temperature, and humidity; and eliminates errors due to these variables.
The disposable mouthpiece acts only as a hygienic barier and does not affect the flow of air or the reading by the transducers. Since the one time use spirette has no reading capabilities, it does not perform a measurement function and does not require calibration.
