Why are PA catheters used in the critical care setting? Who is an appropriate candidate for a PA catheter? How do I place a PA Catheter? Use clinical situation to guide therapies! When can the numbers be misleading? Mitral regurgitation? Loop in RV? Keep balloon inflated, keep advancing!

Continuous cardiac output (CCO) pulmonary artery catheters (PACs) are used in cardiac surgical patients for hemodynamic monitoring. This is an invasive technique; therefore, it has well-known mechanical and infectious complications related to its use.

The inclusion of PVR (PVR = [mPAP – PCWP]/CO) in the definition of pre-capillary PH is essential as this allows discrimination of elevation of PAP caused by pulmonary vascular disease from those resulting from left heart disease or high CO.

Jun 3, 2017 · PVR represents the afterload on the right ventricle. When pressures in the pulmonary vasculature rise, as is seen with volume overload or left heart failure, PVR increases, which results in an increased afterload for the right ventricle.

cians assess cardiovascular function and guide treatment decisions.* Advanced hemodynamic parameters provided include continuous cardiac output (CCO) and mixed venous oximetry (SvO 2), in addition to right ventricular ejection fraction (RVEF) and right ventricular end diastolic volume (RVEDV), to allow con.

Pulmonary vascular resistance (PVR) plays a major role in congenital heart management and critical decision. The impact of pulmonary vascular disease in the early and late morbidity and mortality after cardiac surgery and interventional catheterization in congenital heart defect (CHD) highlights the importance of critical evaluation for PVR.

In this review, which consists of two parts, we will introduce the diference between intermittent pulmonary artery thermodilution using bolus injections, and the contemporary PAC enabling continuous measurements by using a thermal filament which heats up the blood.

Aug 8, 2001 · PCWP (aka LV filling pressure) – approximates LV pressure in diastole (except in mitral stenosis). Normal range around 12. Increased in fluid overload.

We reviewed data for patients seen at referral PH clinics who underwent echocardiography and right heart catheterization within 1 year. We derived equations to estimate PVR based on the ratio of estimated pulmonary artery (PA) systolic pressure (PASP Doppler) to RVOT VTI.
