Cardiopulmonary unloading augments carotid baroreflex gain in healthy men; extends baroreflex interaction models but leaves clinical translation open.
Does unloading cardiopulmonary receptors via lower body negative pressure improve carotid baroreceptor responsiveness in healthy men?
Reductions in central venous pressure augment both heart rate and blood pressure carotid baroreflex responses in humans, likely by reducing inhibitory influence from cardiopulmonary receptors.
Pawelczyk et al. (1989) studied this question.
