Abstract: The present inventive concept relates to an apparatus and a method for providing a treatment plan by measuring the severity of sleep apnea and causes thereof.

Abstract: Disclosed is a fabric electrode belt for measuring a biometric signal. The fabric electrode belt for measuring a biometric signal according to an embodiment of the disclosure includes: a belt body unit including a stretchable material, and provided with electrodes to be in contact with a subject to be examined; and a circuit unit coupled to the belt body unit and configured to receive an electric signal based on impedance of a subject to be examined, measured by the electrodes, the circuit unit being disposed between the belt body units.

Abstract: Provided is a method for calculating a hemodynamic variable for a subject based on electrical impedance tomography (EIT). The method may include: obtaining EIT images at discrete time points in a cardiac cycle of a subject by targeting a chest portion of the subject; identifying, in the EIT images, values of a first pixel in a region corresponding to the heart and values of a second pixel in a region corresponding to a lung, wherein the values of the first pixel are associated with the discrete time points, respectively, and the values of the second pixel are associated with the discrete time points, respectively; and calculating at least one hemodynamic variable on the basis of a first time point associated with a minimum value among the identified values of the first pixel and a second time point associated with a maximum value among the identified values of the second pixel.

Abstract: A body fat measurement apparatus, according to the present invention, comprises: an electrode unit which has a plurality of electrodes and can be worn around the body of the subject to be measured; a first measurement unit which is for obtaining a three-dimensional image of the subject's body part to be measured; a second measurement unit which is for measuring the impedance by means of injecting a current into the electrodes; and a control unit which is for restoring the conductivity and permittivity images of the subject by means of the three-dimensional image and the impedance value and thus separately calculating the amount of subcutaneous fat and visceral fat. According to the present invention, measurement accuracy of the subcutaneous fat and visceral fat can be improved even at a low cost.

Abstract: The present invention relates to a sleep apnea monitoring system for monitoring the sleeping state of a user by means of impedance tomographic image information about the properties of biological tissue and biological signals of the user's body parts to be monitored. The present invention can be manufactured into a very simple portable device and thus enables monitoring during natural sleep at home. Therefore, the present invention enables utilization of obtained information during a sleeping state for diagnosis of and therapeutic plans for sleep apnea.
