Microprocessor-based cardiopulmonary monitoring system

The system uses a dedicated microprocessor for transducer control and data acquisition and analysis. No data will be stored in this system, but the data will be transmitted to the onboard data system. The data system will require approximately 12 inches of rack space and will consume only 100 watts of power. An experiment specific control panel, through a series of lighted buttons, will guide the operator through the test series providing a smaller margin of error. The experimental validity of the system was verified, and the reproducibility of data and reliability of the system checked. In addition, ease of training, ease of operator interaction, and crew acceptance were evaluated in actual flight conditions.
