Key result
An air pressure sensing system using Hilbert-Huang transformation detected significant differences in arterial reflection and stiffness indices between subjects with well-controlled and poorly controlled diabetes.

Does an air pressure sensing system (APSS) for radial arterial waveforms provide reliable measurements of arterial stiffness and indicate diabetic control?
An air pressure sensing system using radial arterial waveforms provides reliable measurements of arterial stiffness that correlate with age and diabetic control.
Wu et al. (2010) conducted a cross-sectional in Diabetes and arterial stiffness (n=108). Air pressure sensing system (APSS) with Hilbert-Huang transformation (HHT) vs. Conventional photoplethysmography (PPG) method was evaluated on Reflection index (RI) and stiffness index (SI). An air pressure sensing system using Hilbert-Huang transformation detected significant differences in arterial reflection and stiffness indices between subjects with well-controlled and poorly controlled diabetes.
