I know this. Since, you have a picture, you obviously have made them. I just want to borrow one for testing. If it works, there would be considerable quantity and we would make them. How do I go about testing? As you say "Fully assembled board (shown above) developed for testing and performance validation only" This is what I want to do.

Hi Marc,
Perhaps the way the note below the picture is worded can be somewhat misleading. The testing and validation performance is done solely by TI for proving the concept and for the collection of data as shown in the reference guide for the design. This allows for the design to be more than just a theoretical paper design. Occasionally TI does make some of these designs available for purchase, but more often than not we only build the design for testing within TI. We do not 'loan' out boards to be tested by customers. As Joseph mentioned you can use the design files to build your own board.

Hi Marc,
This PTT solution was not intended to meet FDA requirements for blood pressure monitors. As we know PTT measurements involve simultaneous sampling of one's ECG and PPG, our goal was only to develop a solution that would synchronize the two measurements together. By synchronizing the ADS1292 and the AFE4404 to the same clock and configuring them for the same data rate, we were able to devise an algorithm that calculated the PTT based on the R-peak of the ECG and the max slope in the PPG.
As you seem to know, PTT is one of several factors that must be considered when estimating a patient's blood pressure. We decided to leave it up to the medical experts to use this information in their own algorithms with proper calibration for each patient. From what I've read, many studies show the correlation between blood pressure and PTT, but the algorithms do vary, so we will not focus on that aspect of the solution.
I hope this clarifies our intent with this design.
Best Regards,
OK, I went to download the information and files on the reference design. They were gone. How do I get access again? Marc
