With each measurement, there is a precise and direct digital sound pulse transit time flow determination of lung function. Every system, every examination result – always the same accuracy and precision.
Two diagonally opposite ultrasound transducers alternately send and receive ultrasonic waves. Without any air flow inside the breathing insert, the transit time of the ultrasound waves is the same in both directions.
Any air flow inside the insert will accelerate the waves in one direction and decelerate in the other. The difference between the transit times of the ultrasonic waves allows to calculate the flow.
Flow and gas density are calculated from the measured transit times, allowing changes in the concentration of the exhaled gases to be determined directly and at the same time with the respiratory volume.
All other factors (gas properties, humidity and temperature) are the same for both directions and cancel each other out.
