Abstract:
Heart rate variability (HRV) and pulse rate variability (PRV) are used as meaningful indicator of cardiovascular circulation assessment. However, both HRV and PRV are limited by the timescale of the heart beat and pulse wave series. Recently, a novel adaptive method based on Hilbert-Huang transform (HHT), named instantaneous pulse rate variability (iPRV), was proposed. It provides a new indication, called very high frequency band (VHF; 0.4-0.8Hz) for the neural regulatory estimation and peripheral responses. Ten healthy subjects participated this study and photoplethysmography (PPG) signal was recorded in supine baseline and during head-up tilt (HUT) and passive leg raising (PLR). The results showed that the spectral power of VHF decreased during HUT and increased during PLR, which might present the compensated regulation of venous return and fluid responsiveness. This study showed that VHF index has potential to indicate the fluid responsiveness and provides the meaningful information for homecare application, which only requires the simple PPG measurement.
