Spontaneous cardiac baroreflex sensitivity during hyperinsulinaemichypoglycaemia under normoxic and hyperoxic conditions. Group average regressions between heart rate and systolic blood pressure are presented with operating points (Mean±SEM). Baseline sCBRS measures were not different between visits (p=0.26) and were thus averaged. sCBRS was significantly reduced from baseline during hypoglycemia and the baroreflex working range was shifted to higher heart rates. Hyperoxia did not alter sCBRS, however the baroreflex working range was shifted back toward baseline levels.
