Wearable radio-frequency sensing of respiratory rate, respiratory volume, and heart rate [PDF]
npj Digital Medicine, 2020 Many health diagnostic systems demand noninvasive sensing of respiratory rate, respiratory volume, and heart rate with high user comfort. Previous methods often require multiple sensors, including skin-touch electrodes, tension belts, or nearby off-the ...

Extracting Instantaneous Respiratory Rate From Multiple Photoplethysmogram Respiratory-Induced Variations [PDF]
Frontiers in Physiology, 2018 In this study, we proposed a novel method for extracting the instantaneous respiratory rate (IRR) from the pulse oximeter photoplethysmogram (PPG). The method was performed in three main steps: (1) a time-frequency transform called synchrosqueezing ...

Utility of a Card-Type Respiratory Rate Measuring Device for Spontaneously Breathing Patients [PDF]
DiagnosticsBackground/Objectives: Accurate measurement of respiratory rate (RR) is critical for early detection of patient deterioration. A newly developed contactless card-type device measures RR and heart rate (HR) by detecting chest impedance changes.

Three methods for determining respiratory waves from ECG (Part I) [PDF]
Metrology and Measurement Systems, 2023 In the diagnosis of many disease entities directly or indirectly related to disorders of respiratory parameters and heart disease, an important support would be to estimate the temporal changes in these parameters (most often respiratory wave (RW) and ...

Estimating Respiratory Rate From Breath Audio Obtained Through Wearable Microphones [PDF]
Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2021 Respiratory rate (RR) is a clinical metric used to assess overall health and physical fitness. An individual’s RR can change from their baseline due to chronic illness symptoms (e.g., asthma, congestive heart failure), acute illness (e.g., breathlessness

Respiratory Rate Estimation Based on WiFi Frame Capture [PDF]
Consumer Communications and Networking Conference, 2021 This paper presents a method that estimates the respiratory rate based on the frame capturing of wireless local area networks. The method uses beamforming feedback matrices (BFMs) contained in the captured frames, which is a rotation matrix of channel ...
