Overview of Hemodynamics
Click on the video arrow below. It demonstrates where a Swan-Ganz PA catheter is placed and the wave forms that would be seen on the monitor as it is inserted.
Hemodynamics, by definition, is the study of the motion of blood through the body. In a simple patient assessment this may include the observation of a patient’s heart rate, pulse quality, blood pressure, capillary refill, skin color, skin temperature, and other parameters.
As a patient's condition worsens, invasive hemodynamic monitoring may be utilized to provide a more advanced assessment and to guide therapeutic interventions.
Hemodynamic pressure monitoring systems detect changes in pressure within the vascular system and convert those changes into digital signals. The digital signals are then displayed on a monitor as waveforms and numeric data.
Invasive hemodynamic monitoring is used routinely in many critical care units to assist in the assessment of both single and multi-system disorders and their treatment.
Hemodynamic monitoring might include waveform and numeric data derived from the central veins, right atrium, pulmonary artery, left atrium, or peripheral arteries.
The data provided by invasive hemodynamic monitoring does not take the place of careful nursing assessment. Thorough nursing assessment provides the framework for interpretation of hemodynamic data and aids in selection of interventions that enhance patient outcomes.
