Recent development of respiratory rate measurement technologies
Physiological Measurement, 2019 Respiratory rate (RR) is an important physiological parameter whose abnormality has been regarded as an important indicator of serious illness. In order to make RR monitoring simple to perform, reliable and accurate, many different methods have been ...

Current clinical methods of measurement of respiratory rate give imprecise values
ERJ Open Research, 2020 Background Respiratory rate is a basic clinical measurement used for illness assessment. Errors in measuring respiratory rate are attributed to observer and equipment problems. Previous studies commonly report rate differences ranging from 2 to 6 breaths·

Non-Contact Monitoring of Breathing Pattern and Respiratory Rate via RGB Signal Measurement
Italian National Conference on Sensors, 2019 Among all the vital signs, respiratory rate remains the least measured in several scenarios, mainly due to the intrusiveness of the sensors usually adopted.

Measurement of respiratory rate with inertial measurement units
Current Directions in Biomedical Engineering, 2020 Demographic changes and increasing air pollution entail that monitoring of respiratory parameters is in the focus of research. In this study, two customary inertial measurement units (IMUs) are used to measure the breathing rate by using quaternions. One
