Controlled breathing protocols probe human autonomic cardiovascular rhythms

The purpose of this study was to determine how breathing protocols requiring varying degrees of control affect cardiovascular dynamics. We measured inspiratory volume, end-tidal C02, R-R interval, and arterial pressure spectral power in 10 volunteers who followed the following 5 breathing protocols:
