1. A cardiac support system comprising:
a fluid channel passing through the cardiac support system configured to permit fluid to flow therethrough;
a first pressure sensor configured to determine at least one of a static pressure or a total pressure in a first region of the cardiac support system having a first cross-sectional area; and
a second pressure sensor configured to determine at least one of a static pressure or a total pressure in a second region of the cardiac support system having a second cross-sectional area of a different size relative to the first cross-sectional area;
wherein:
the fluid channel has a longitudinal axis;
the cardiac support system has one or more side walls extending parallel to the longitudinal axis;
the first pressure sensor and the second pressure sensor are disposed on the one or more side walls; and
at least one of the first pressure sensor and the second pressure sensor is disposed on an outer side of the cardiac support system.
