Key result
Respiratory blood pressure variations in normal subjects involve changes in both cardiac output and peripheral resistance that interact similarly to coupled electronic oscillators.

Respiratory variations in blood pressure are driven by interactions between cardiac output and peripheral resistance.
A study of respiratory blood pressure variations in normal subjects suggests that variations in both cardiac output and peripheral resistance are involved, the latter mechanism being essentially similar to that producing the Traube waves in apnea. The interactions of the two mechanisms are compared to the known behavior of coupled electronic oscillators.
