Abstract
The aim of this paper was to revise the several homodynamic variables that can be monitored by invasive techniques, direct or indirectly, such as arterial pressure, central venous pressure, cardiac output, systemic vascular resistance, among others. Such techniques offer more accuracy and reliability, and also allow a continuous monitoring, being of great importance and utility in the treatment of the critically ill patient. As they are invasive techniques, they aren't free of risks and the professional must decide for their utilization analysing the advantages and disadvantages.
