ABSTRACT
Many studies have indicated the microcirculation can directly respond to disease-related symptoms. However, the capacity of microcirculation would vary due to the gender differences. Near-infrared spectroscopy (NIRS) is a noninvasive technique to monitor tissue oxygenation dynamics. In this study, the far-infrared (FIR) source was used for physiological intervention of microcirculation. The experimental results show that the nature difference of oxygenation status exists between male and female during FIR irradiation. Therefore, we suggest the NIRS-based assessment should be calibrated with the gender-related effect for clinical diagnosis of peripheral arterial disease.

pone.0135166.g002: Temporal tracings of signal response to FIR illumination of all subjects.

Mentions: The mean of all subjects can be used to determine the slope to indicate the increase (or decrease) in temperature per minute at the FIR illumination step. The slope of Δ[HbO2] and Δ[Hb] among all subjects was 0.29 ± 0.20 μM·min-1 and -0.03 ± 0.09 μM·min-1, respectively. Fig 2 shows the mean values of the temporal tracings of tissue oxygenation in all subjects. During FIR illumination, the forearm temperature increased steadily. FIR illumination can improve microcirculation through its thermal effects. The concentration of HbO2 increased and the concentration of Hb decreased. At the recovery step, Δ[HbO2] continued to increase slightly because of nonthermal effects [13]. The results prove that NIRS measurement can be performed to directly monitor changes in microcirculation.
