The spirometer sensor measures airflow during patient inhalation and exhalation.
The sensor converts airflow into an electrical signal using an ultrasonic method.
The ultrasonic measurement method provides high resolution (250 measurements per second) and ensures reliable determination of all measured parameters with the highest accuracy.
When using ultrasonic flow measurement based on digital technology, auxiliary flow assessment parameters (such as differential pressure) are no longer required. Gas flow and volume are calculated based on measuring the transit time of an ultrasonic pulse in forward and reverse directions. The time difference between forward and reverse directions is proportional to airflow velocity.
Ultrasonic measurements provide a reliable and stable diagnostic basis and ensure maximum patient comfort. Unlike similar devices, the SMP 02 RD has no noticeable resistance that could make breathing difficult, which is especially important for patients with impaired respiratory function.
