04Doppler Flow Velocity System

A noninvasive solution to serially quantify
changes in hemodynamics and
cardiovascular function in small animals

The Indus Doppler Flow Velocity system is used to noninvasively 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.
