  • Patent number: 12159717
    Abstract: A technology for obtaining a respiratory rate from a photoplethysmogram (PPG) signal. In one example, an artificial neural network model can be trained to predict a respiratory rate using a training dataset containing PPG data. The artificial neural network model can include a first series of convolutional layers to remove artifacts from a PPG signal, a fast Fourier transform (FFT) layer to convert the PPG signal to PPG frequency representations, and a dense layer to decode the PPG frequency representations to respiratory rate predictions. After training the artificial neural network model, PPG data generated by a pulse oximeter monitor can be obtained, and the PPG data can be input to the artificial neural network model. The artificial neural network model outputs a respiratory rate prediction, wherein the respiratory rate prediction represents the respiratory rate obtained from the PPG signal.

  • Publication number: 20210106240
    Abstract: A technology for obtaining a fetal heart rate from an electrocardiogram (ECG) signal. In one example, an artificial neural network model can be trained to predict a fetal heart rate using a training dataset containing ECG data. The artificial neural network model can include a first series of convolutional layers to separate a fetal ECG signal from a maternal ECG signal, a fast Fourier transform (FFT) layer to convert the fetal ECG signal to ECG frequency representations, and a dense layer to decode the ECG frequency representations to fetal heart rate predictions. After training the artificial neural network model, ECG data generated by an ECG monitor can be obtained, and the ECG data can be input to the artificial neural network model. The artificial neural network model outputs a fetal heart rate prediction, wherein the fetal heart rate prediction represents the fetal heart rate obtained from the ECG signal.
