Abstract
The effect of breathing on cardiac performance has long been suspected. As early as
1853, Donders (1) made observations that spontaneous inspiration has the dual effect
of increasing the return of venous blood to the heart while decreasing the ejection of
blood into the systemic circulation. Since Donders, many others have investigated the
effects of breathing on right and left heart dynamics. Most studies have required invasive surgical techniques to open the chest and insert instrumentation (i.e., ultrasonic
flowmeters, pressure-tip or liquid-filled catheters, implanted metallic markers) (2-4)
to facilitate measurement of hemodynamic and cardiac dimensional changes in response to various breathing protocols. Similarly difficult instrumentation challenges
have been faced by those studies interested in evaluating the role of the intrathoracic
environment on pulmonary function. Because of the complex interplay between the
heart and lungs within the thorax, these invasive procedures most certainly alter the
normal interaction between the two physiologic systems.
