CardioPulmonary Coupling(abbreviation：CPC)，Based on single lead electrocardiogram (ECG) recording during sleep, CardioPulmonary Coupling (CPC) technology first extracts normal sinus rhythm time series and the respiration time series derived from the ECG, then calculates the degree of coherence and the cross spectrum of these two signals using the Hilbert-Huang Transformation (HHT) technology, and finally obtains the sleep clinical stage results. CPC can precisely identify the clinical stages of sleep, including deep/restful sleep, disturbed sleep, REM, wake, and sleep apnea. The results are verified to be consistent with the traditional EEG-based sleep study.
Several tens of CPC related clinical papers has been published, including 10+ papers were published in <<Sleep Medicine>> and <<Sleep>>. CPC sleep quality analysis system has obtained the FDA 510(K) certification (K070855 and K112573) in US and CFDA certification (JiangSu: 20152700571) in China.
CPC sleep quality testing system includes two parts: the analysis software and ecg signal acquisition instrument analysis software using CardioPulmonary Coupling analysis method of harvard medical school (CardioPulmonary Coupling), small and light CPC ecg signal acquisition instrument (with obstacles to minimize), will not affect the normal sleep, can be used in routine conditions.
CPC sleep quality detection system by ecg signal for the human body nervous system control of the plant cardiopulmonary coupling relationship between spectrum, accurately identify every minute of sleep stages,including deep sleep, shallow sleep, dream, wake up, sleep apnea,In view of apnea, can distinguish between the central type and block type.
CPC makes it possible for sleep test popularization, makes originally trival, expensive sleep test to be simple and easy.The customers can test sleep quality in the most natural condition detection,also can detect in the ward, can also be home to test.
Simple operation, automatic analysis and generate reports, no specialized technical personnel.
Relatively (PSG traditional analysis equipment) cost is low.
Based on the network platform, suitable for a wide range of ward work and community screening.
Suitable for children and the elderly who is using badly of PSG.
Small volume, no wires, the participants will not be disturbed by instrument, easy to operate,can detect that occupy at home,accord with the normal sleep habits.
Can be a large number of screening, high accuracy,lower price,also can do multiple screening and follow-up tracking detection.
CPC is the automatic interpretation of artificial intelligence, get the reports quickly and can eliminates human error.
