Blood Pressure

Arterial Blood Pressure Waveforms data using Millar CatheterUsing Millar Catheters to Measure Blood Pressure

Blood pressure is defined as the amount of pressure exerted by the blood on the vessel wall and is regulated by the cardiovascular system. The insights made possible by accurate high fidelity, beat-by-beat measurement of blood pressure form the basis of many successful cardiovascular research programs.

Arterial blood pressure provides a measure of systemic blood pressure and is the most common method for monitoring basic cardiovascular parameters. Mikro-Tip catheters can be quickly delivered via peripheral vessels like the carotid and femoral arteries for routine blood pressure monitoring. The high-fidelity waveforms produced by these measurements are used to derive mean arterial pressure (MAP), systolic and diastolic pressures and pulse pressure. These parameters are ideal for both acute and chronic cardiovascular monitoring.

For more in depth analysis, ventricular blood pressure and/or PV loops can also be monitored to provide a more complete assessment of total cardiovascular function.
