Research Abstract |
As a first step in the assessment of cardiovascular dynamics at night, we investigated it in the daytime, responses in the modulation of blood pressure to mental stress. Also, to be an assist of labor safeties in workers they are unaware of their chronic obstructive pulmonary disease (COPD), the healthy subjects were exposed to hypoxic (12.7% O2) and their cardiovascular responses to mental stress were evaluated in both normoxic and hypoxic condition. The performances and the elevations of blood pressure to mental task were equally in both normoxia and hypoxia condition. However, the sympathetic vasoconstriction to mental task was decreased in only hypoxic condition. Based on these results, the cardio vascular responses to mental stress in hypoxic condition, especially in the sympathetic vasoconstriction, appear to be differ from in normoxic conodition.
