Why the study?
Does CO2 chemoreceptor stimulation interact with arterial baroreflexes to alter R-R intervals and arterial pressure in healthy young adults?
Population
10 supine healthy young men and women

Baseline pressure should be accounted for in chemoreflex testing; leaves open relevance to hypertension or HF populations.
Does CO2 chemoreceptor stimulation interact with arterial baroreflexes to alter R-R intervals and arterial pressure in healthy young adults?
CO2 chemoreflexes interact with arterial baroreflexes such that the effect of CO2 on arterial pressure and R-R intervals is dependent on baseline arterial pressure.
