FIELD: medicine.
SUBSTANCE: method of obtaining information about the vital signs of the subject is performed using a device for obtaining information about the vital signs. In this case, using the first detection unit, a first set of image data is detected from the skin area to isolate the first signal associated with the first vital sign. First detection unit is located in a remote position relative to the subject and is configured to concentrate on a smaller field of view. Using the second detection unit, a second set of data detected from a part of the body that is different from the skin area is obtained in order to highlight the second signal associated with the second vital sign. Second detection unit is placed in contact with the subject. First and second vital signs are heart rate information or breathing information. With use of the analysis block, the first signal is extracted with information about vital signs from the first set of detected data using photoplethysmography and the signal of movement of the indicated body part is extracted as the second signal with information about vital signs from the second set of detected data. Motion signal contains an overlay of breathing and heart rate information. Using the processing unit combine the first and second signals to obtain a combined signal. Using the processing unit, remove information about the heart rate from the motion signal using the selected heart rate signal and weigh the first and second signals using the first and second quality indicators, respectively, and combine the weighted first and second signals to obtain a weighted signal. With use of the selection block, vital signs are separated from the combined signal and respiration information from the processed motion signal. With use of the comparison unit, information on breathing from the motion signal and additional information on breathing from the heart rate signal are compared. With use of the alarm unit, an alarm is issued if the breath information signal and the breath additional information signal differ from each other by an amount greater than a predetermined value. Enter information using the user interface.
EFFECT: reliable information is obtained about the frequency of respiratory movements, as well as the extraction of information about breathing from motion signals, which make it easier to further refine the received signals with reduced requirements for computing and computer facilities.
