Resumen

CASTILLO MOYA, Andrés  y  DEL POZO BASCUNAN, Paulina. Cardiopulmonary Interactions: From Physiology to Clinic. Rev. chil. pediatr. [online]. 2018, vol.89, n.5, pp.582-591. ISSN 0370-4106.  http://dx.doi.org/10.4067/S0370-41062018005000905.

Cardiopulmonary Interactions (CPI) refer to the interplay between the respiratory and cardiovascu lar systems during the respiratory and cardiac cycle. These interactions vary depending on whether the patient is in spontaneous or mechanical ventilation and affect the preload and afterload of both ventricles at different levels. Understanding CPI is essential to the management of critically ill pa tients, where preload and afterload manipulations are specialy important to optimize cardiac output and oxygen delivery to the periphery. The present article reviews the physiological principles required to understand CPI in patients both in spontaneous and mechanical ventilation using specific clinical scenarios to facilitate its use as part of day to day clinical practice.

Palabras clave : interactions; cardiopulmonary; preload; afterload; intrathoracic pressure; transmural pressure; pulmonary vascular resistance; ventricular interdependence.
