Respiration Rate Monitoring Using Optical-Based Sensor Integrated in Portable on Bed Device System

Coronavirus disease (COVID-19) which is caused by the SARS-CoV-2 virus has caused significant effects on human health including shortness of breath or breathing difficulty. People with severe COVID-19 may remain infectious beyond 10 days. As the positive number of COVID-19 infectious patients in each country could increase higher that the capacity of available hospital beds, less critical cases will have to continue self-isolation at their respective home. The respiration rate monitoring device under investigation is based on optical fiber sensor integrated in a portable on bed device. Based on the experimental results, the device is able to provide continuous measurement of the breathing rate or normal and abnormal rates which ranged between 12 and 18 and 6–24 times per minutes, respectively. The investigated optical fiber respiration sensor is an acceptable alternative method for continuous respiration rate measurement including for COVID-19 patient under home quarantine.
