Abstract:
Body temperature is an important homeothermic autoregulation of humans. Body temperature is usually controlled by autonomic nervous system (ANS). When a person has suffered a virus or bacterial infection, it causes fever. The ANS rises the body temperature by tachycardia and cutaneous vasomotion. The common non-invasive indication for ANS is based on heart rate variability (HRV) and pulse rate variability (PRV). However, these two methods are limited by the timescale of time series. Instantaneous PRV (iPRV) was proposed as a surrogate of HRV in frequency domain and breaks the restriction of timescale. In this paper, thirty subjects were recruited for the study; the body temperature and the photoplethysmography (PPG) signal were acquired in supine position for ten minutes. Fifteen fever subjects, whose body temperature was higher than 37.9 °C, are in Group Fev., the others are in Group Ctr. The results show that the power of iPRV in normalized low frequency (nLF) in Group Fev.(0.63±0.13, p<0.05) was significantly higher than that in Group Ctr.(0.47±0.16). And the power of iPRV in normalized high frequency (nHF) in Group Fev.(0.38 ±0.13, p<0.05) was significantly lower than that in Group Ctr.(0.54±0.16). Besides, the nVHF might have a potential for indicating the peripheral circulation and providing more information about body regulation.
