ABSTRACT

Introduction: In this article we present assessing hemodynamics which may be carried out through an arterial blood gas and a vein gas samples, which represent the continuation of the journey of the oxygen since it comes to arterial blood to be delivered to the tissues, and the remaining oxygen that came into the right atrium, this way we can assess indirectly the cardiac output. Methods: We will explain the formulas that evaluate the blood content of oxygen, venous content of oxygen, as well as arteriovenous differences, which represent the amount of oxygen that remains in circulation after its passage by the capillaries, rate of extraction of oxygen, which determines the amount of oxygen that is consumed by the tissues, and we will finish with the establishment of the formula to calculate the cardiac output. Conclusions: By assessing hemodynamics we can determine indirectly alterations in the systemic circulation, as well as alterations in tissue oxygenation, also describes the causes that condition and these alterations.
