1. An apparatus comprising:
a sensor module comprising:
a) an arterial catheter connection hub;
b) a preservation inflow hub coupled through an arterial blood chamber to said arterial catheter connection hub;
c) a venous catheter connection hub;
d) an effluent outflow hub coupled through a venous blood chamber to said venous catheter connection hub;
e) an arterial sensor, a venous sensor, a processor and an input/output device;
f) said arterial sensor comprising:
i) a light source configured to emit light into said arterial blood chamber,
ii) a light detector configured to detect said light in said arterial blood chamber, said light from said light source from said arterial sensor,
iii) a temperature sensor configured to measure temperature in said arterial blood chamber,
iv) said arterial sensor configured to measure inflow data comprising light data from said light detector from said arterial sensor and temperature data from said temperature sensor from said arterial sensor of fluid flowing through said arterial blood chamber without direct contact with said fluid flowing through said arterial blood chamber;
g) said venous sensor comprising:
i) a light source configured to emit light into said venous blood chamber,
ii) a light detector configured to detect said light in said venous blood chamber, said light from said light source from said venous sensor,
iii) a temperature sensor configured to measure temperature in said venous blood chamber, and
iv) said venous sensor configured to measure effluent data comprising light data from said light detector from said venous sensor and temperature data from said temperature sensor from said venous sensor of fluid flowing through said venous blood chamber without direct contact with said fluid flowing through said venous blood chamber; and
h) said processor configured to determine a ratio of said inflow data to said effluent data and said input/output device configured to display said ratio, or said inflow data and said effluent data, or a complete message or light when said ratio has reached 1±10%.
