In nowadays intensive medical care ARDS (acute respiratory distress syndrome) became one of the most problematic disease patterns. Mortality rate for ARDS is still between 40 and 60 percent.

A newer treatment option for this illness is the extracorporeal oxygenation. Here the patient is connected to an oxygenator. This device realizes a high percentage of the needed gas exchange with the blood outside the human body. The lung is disencumbered during this procedure in order to have a chance to regenerate faster.

The overall aim of the project SmartECLA is to optimize the used devices for the extracorporeal oxygenation according to the medical requirements and to develop a safety driven closed-loop control for this system. SmartECLA is part of a research network of 6 chairs out of 4 different faculties founded by the DFG.

The concept of system planes several autonomous devices that shall communicate with each other via CAN-Bus. It is the task of the described thesis to work out a fault tolerant CAN Protocol definition with respect to the special needs of the project. Therefore also existing CAN-Protocols should be looked at and based on these protocols a specification shall be developed.

• Familiarize with the topic
• Point out the requirements towards the communication-protocol
• Comparison with existing CAN-Protocols
• Detailed specification of the developed CAN-Protocol
• Exemplary implementation
• Documentation of the results

The aim of the thesis is to create a detailed definition for the CAN-Protocol that shall be used in the project SmartECLA.
