Estimation of respiratory waveform and heart rate using an accelerometer.
In this paper the use of an accelerometer to measure cardio-respiratory activity is presented. Movement of the chest was recorded by an accelerometer attached to a belt around the chest. The acquisition is realized in different status: normal, apnea, deep breathing or after exhaustion and also in different postures: vertical (sitting, standing) or horizontal (lying down). The resulting signal was compared with reference measurements. The results of experimental evaluation indicate that using a chest-accelerometer can correctly detect the respiratory waveform and heart rate (HR) signal. This method is therefore suitable for automatic identification some disease, for example arrhythmia or sleep apnea.
