[The pulmonary artery catheter in the intensive cardiac care unit]. / Il catetere arterioso polmonare in terapia intensiva cardiologica.

ABSTRACT

More than 50 years after its introduction in clinical practice, the increase in the intensity of care offered by the cardiac intensive care units, the shift in the population of patients treated and the wider availability of circulatory supports, still makes the pulmonary artery catheter (PAC) an essential tool for diagnosis, monitoring and prognosis in patients suffering from cardiogenic shock. In this review, we will discuss how to identify those patients who can benefit most from its use, the configuration and the correct insertion technique of a PAC. A pragmatic guide will also be provided for the interpretation of the hemodynamic indexes (direct and calculated) that the PAC is able to reveal as well as a summary of the most common errors in reading or interpreting the pressure curves provided by the PAC. In this article, we will then present a practical guide on how to use the PAC in a modern cardiac intensive care unit.
