The present invention relates to a device and a method for monitoring pulmonary function using the impedance of both hands, and aims to extract an impedance pulmonary function signal (IPFS), which indicates a change in a pulmonary volume, using the bioelectrical impedance detected from both hands of an evaluation subject. To this end, the present invention provides a device for monitoring the pulmonary function and a method using same, the device comprising: a base impedance signal which obtains a measured area by a current lead-in and a voltage measurement; a bio-signal detection unit that detects the IPFS, which indicates temporal changes of the pulmonary volume according to respiration; a pulmonary function evaluation factor extraction unit, which extracts a parameter for evaluating a pulmonary function condition from the IPFS that has been detected by the bio-signal detection unit; a main control unit, which controls the action of the bio-signal detection unit and the pulmonary function evaluation factor extraction unit; and a data storage unit, which stores the IPFS that has been detected by the pulmonary function evaluation factor extraction unit and the signal that has been extracted by the extraction unit. Therefore, the present invention can solve the restraints of the conventional pulmonary function tests and be actively utilized in long-term monitoring of the pulmonary function and early diagnosis of a disease. |
