Integrated Blood Pressure is used to perform pressure-volume analysis and vascular strain analysis

The Vevo blood pressure input can be adjusted to accept a wide range of voltages from multiple types of blood pressure systems. The input gain of the blood pressure input can be adjusted within the software. Exact positioning of the catheter can also be visualized with the Vevo system.  Left ventricular pressure signals can be transferred into the Vevo Ultrasound System simultaneously with left ventricle view to record real-time left ventricular inner diameter (LVID).  Two-dimensional targeted M-Mode tracings can be recorded through the walls of the left ventricle at a sweep speed of 1540 m/s. The left ventricular pressure waveform input and pressure derivative (dP/dt) are superimposed on the electrocardiogram (ECG) trace and along with heart rate (HR), left ventricular systolic pressure (LVSP), body temperature, and respiratory rate are simultaneously monitored on the Vevo system.  Pressure/Volume loops can be generated within the software.

This option is available for both the Vevo 2100 and Vevo 770 Imaging Systems.
