Hemodynamics is the study of the forces involved in the circulation of blood throughout the body, including cardiac function and peripheral vascular physiology.
Hemodynamics can be monitored with noninvasive and invasive methods. One noninvasive method or technique is the use of a blood pressure cuff. This encircles the arm and measures internal blood pressure. This is noninvasive because it does not require any surgical procedure to utilized.
An example of an invasive method is the use of a Swan-Ganz Catheter. This method requires a catheter to be introduced into the body through a large vein. It is than threaded through the heart and into the pulmonary artery. This method provides a measure of central venous pressure.
