Respiratory Rate

Respiratory rate is the number of breaths within a unit of time, usually per minute. The normal values for normal respiratory rate depend to a large extent on age. At rest it is about 12 – 18 breaths per minute for an adult. However, the values are individually different and depend on various parameters, such as the state of training. A too fast (tachypnoea) or too slow (bradypnoea) breathing rate can lead to threatening situations.

How does our technology measure the respiratory rate?

Our most recent algorithm implementation is extracting the respiratory rate from the PPG signal. It is still in development, but has provided promising results in our first study in cooperation with the Technical University of Munich (TUM) in comparison with a reference spirometer
