Left Atrial and Aortic Flow Measurement :
- Indirect flow measurement by controlling the speed of a peristaltic pump
- Direct flow measurement using ultrasonic transit-time technology
- Requires suitable species-specific flow probes
Intracardial Left Ventricular Pressure Measurement :
- Allows introduction of a tip pressure catheter directly into the left ventricle through the adapter port and aorta
- Avoids the need for apical puncture

Perfusate Oxygenation :
- Suitable for oxygenation of buffer solutions containing albumin, fatty acids, washed erythrocytes or other foaming additives
Perfusate Filtration :
- Provides filtration of recirculated perfusate
Temperature Measurement :
- Enables measurement of perfusate temperature
- Suitable for specific temperature studies and special temperature protocols such as cooling or transplantation studies
Perfusion Solution Monitoring :
- Continuous or intermittent measurement of pO2
- Continuous or intermittent measurement of pH
- Continuous or intermittent measurement of pCO2
Drug Addition :
- Supports drug addition where flow is measured or calculated
- Suitable when drugs must be added according to a specific flow ratio
Pacing Option :
