Cheyne-Stokes respiration (CSR) is a sleep-disordered respiration characterised by recurrent central apneas alternating with hyperventilation exhibiting a crescendo-decrescendo sample of tidal quantity. This respiration is reported in sufferers with coronary heart failure, stroke or injury in respiratory facilities.
It will increase mortality for sufferers with extreme coronary heart failure because it has adversarial impacts on the cardiac perform. Early stage of CSR, additionally known as periodic respiration, is usually undiagnosed because it solely provokes hypopneas as an alternative of apneas, that are way more troublesome to detect. This paper demonstrates the proof of idea of a brand new technique dedicated to the early detection of CSR. The proposed strategy depends on a sign demodulation method utilized to air flow indicators measured on 15 sufferers with persistent coronary heart failure whose respiration goes from regular to extreme CSR.
Based mostly on a modulation index and its instantaneous frequency, oscillation zones are detected and labeled into three classes: CSR, periodic respiration and no irregular sample. The modulation index is used as an environment friendly indicator to quantify the diploma of certainty of the pathology for every affected person. Outcomes present excessive correlation with consultants’ annotations with sensitivity and specificity values of 87.1% and 89.8% respectively. A ultimate determination results in a classification which is confirmed by the consultants’ conclusions. (See quotation beneath)
