Key result
This review evaluates contact and remote breathing rate monitoring techniques, noting that non-contact methods improve patient comfort but involve higher set-up complexity.
Why the study?
Breathing rate monitoring is essential for hospitalized patients with COVID-19, motivating a review of recent contact and remote monitoring implementations.
Remote breathing monitoring techniques offer improved patient comfort and accuracy for COVID-19 screening, despite higher setup complexity compared to contact methods.
Non-contact breathing monitoring may improve comfort; leaves open prospective validation before clinical adoption.
Breathing rate monitoring is a must for hospitalized patients with the current coronavirus disease 2019 (COVID-19). We review in this paper recent implementations of breathing monitoring techniques, where both contact and remote approaches are presented. It is known that with non-contact monitoring, the patient is not tied to an instrument, which improves patients' comfort and enhances the accuracy of extracted breathing activity, since the distress generated by a contact device is avoided. Remote breathing monitoring allows screening people infected with COVID-19 by detecting abnormal respiratory patterns. However, non-contact methods show some disadvantages such as the higher set-up complexity compared to contact ones. On the other hand, many reported contact methods are mainly implemented using discrete components. While, numerous integrated solutions have been reported for non-contact techniques, such as continuous wave (CW) Doppler radar and ultrawideband (UWB) pulsed radar. These radar chips are discussed and their measured performances are summarized and compared.
