Choate, Julia K.; Denton, Kate M.; Evans, Roger G.; Hodgson, Yvonne – Advances in Physiology Education, 2014
During underwater submersion, the body responds by conserving O[subscript 2] and prioritizing blood flow to the brain and heart. These physiological adjustments, which involve the nervous, cardiovascular, and respiratory systems, are known as the diving response and provide an ideal example of integrative physiology. The diving reflex can be…

Hodgson, Yvonne; Choate, Julia – Advances in Physiology Education, 2012
The Finapres finger cuff recording system provides continuous calculations of beat-to-beat variations in cardiac output (CO), total peripheral resistance, heart rate (HR), and blood pressure (BP). This system is unique in that it allows experimental subjects to immediately, continuously, and noninvasively visualize changes in CO at rest and during…
