“…Cutaneous blood flow (numerator) decreased after systemic hypoxia in our study concurrent with a decrease in the microcirculatory cross-section (denominator) due to a reduction in the bicarbonate level. A similar compensatory mechanism was described during hemorrhage, using the monitoring of the LDF signal (Ovadia et al, 1995). These mechanisms could explain the similar rates of change in both skin blood flux and bicarbonate level throughout the experiment.…”

“…One pair, cutaneous and arterial oxygenation, decreased exponentially and highly correlated during hypoxia, reaching the lowest level of the three pairs. It is already known that the skin responds rapidly by peripheral vasoconstriction during physiological stress, such as hemorrhage and hypoxia (Lima and Bakker, 2005;Ovadia et al, 1995;Wright et al, 2006). However, the present study proposes a sensitive noninvasive method to assess changes in arterial oxygen pressure.…”

“…Based on the results of our previous studies, the LPT system can be used as a reliable noninvasive monitor of microcirculatory hemodynamic variables under different clinical conditions such as hemorrhage followed by fluid transfusion [19], different nitrates and vasoactive drugs at different dosages [20] and different respiration rates [21] and during varying degrees of hypoxia [22].…”
