Why the study?
Do heart rate and blood pressure oscillations persist during voluntary apnea in humans, and how do they depend on prior chemoreceptor activity?

May inform research on chemoreflex modulation of apnea-related oscillations; leaves open any clinical relevance or therapeutic implications.
Do heart rate and blood pressure oscillations persist during voluntary apnea in humans, and how do they depend on prior chemoreceptor activity?
Cardiovascular oscillations persist during voluntary apnea in humans, with parameters dependent on prior chemoreceptor activity (atmospheric air vs. oxygen breathing).
Javorka et al. (2002) studied this question.
