Blood Flow Velocity System

The Indus Doppler Flow Velocity system is used to non-invasively evaluate cardiovascular physiology and function primarily in anesthetized mice and rats. Investigators can serially follow changes that occur due to aging, disease progression, remodeling and the effects of surgical or pharmacological interventions. Parameters such as peak and mean FVs, peak and mean accelerations of flow, time durations of cardiac events, transit time of the FV pulse in a vessel segment, areas under the FV curves, pulsatility and resistivity indices, and R-R intervals of electrocardiogram can be measured using the system. Ultrasonic probes with small foot print (2-3mm OD) operating at 10 and 20 MHz are used to measure flow velocities from within both the cardiac system and peripheral vessels, located at about 1-10 mm distance (range gate depth) from the body surface without the need for invasive surgery. The utility and value of the blood flow velocity (FV) measurements using the Doppler Flow Velocity System has been thoroughly demonstrated by numerous investigators who have studied:

• cardiac function (aortic FV-systolic; mitral FV-diastolic);
• myocardial perfusion (coronary FV-coronary flow reserve);
• pressure-overload by stenosis (left & right carotid FVs and stenotic jet FV at aortic arch);
• arterial stiffness (aortic arch & abdominal FVs to determine pulse wave velocity); and
• peripheral perfusion (renal, carotid, iliac, femoral, saphenous vein FVs).

The Indus Doppler Flow Velocity system has been widely accepted in research over the last 20 years and has a strong track record in the literature as a highly accurate and user friendly system. The system can also be used with Doppler Cuff Probes surgically placed around vessels not easily located or to permit measurements in an awake condition using a tethered wire management system. This includes vessels such as the hepatic artery, portal vein, and umbilical artery and can also be used on vessels in larger sized animals.
