Phoenix Ambulatory Blood Pressure Monitor Project
12/10/2006 Meeting Notes




* Larry: Completed Sphygmochron period of wearing an ABPM, no crises. His circadian rhythm is about 3 hours later than Discovered there are cases that are not reported in the current software, like there isn' t enough heart rate variability to perform an analysis. 1) The spreadsheet framework is ready to place it on Sourceforge for version control. Using Sourceforge to keep records to overcome the primitiveness of Sourceforge. Sourceforge will not prevent someone from creating a bad record. For example, completion of a review by multiple users. Next step.
* Chris: Started working on the architectural prototype for the Java based Syphgmochron, ignoring some things and adding other things in, like a framework for managing the algorithms.
Tom: Doing work with Larry, exploring the TDD framework, and looking at the Sphygmochron to see visually how to see the data.
* Gerry: Looking at issues to spin off the critical care software group.
* Brad: Designing an FPGA to capture the measurements and possibly do the calculations of the BP and HR.
* Germaine: Overwhelmed. The recent trip was fantastic, to Japan, a meeting in Tokyo where we met Thomas Pickering, who was interested in blood pressure. He represents a majority of people adverse to using computers and algorithms to analyze BP. They are not conversant with mathematics, computers and algorithms. It must be simple. A mean is simple. But, it ignores the recent discoveries that BP is not constant, and these have diagnostic potential. It is important to get physicians interested and to address their concerns. Also, we had two other side trips. One to Tosa, where there is a community where citizens are offered fulltime ABPM, and nurses who look after them, with a community house where patients can come to learn and use monitors, and physicians can come and learn. The leading physician provided an overview of progress, showing that they had measurable progress in improving their health and how they did it. The other side trip was to Kyoto, where their Healthwatch program had been running for 6 years. This was an important trip in bringing ABPM directly to the patients in a health plan. A&D was a full partner in this project. A&D is working on a new device, a standalone system, that uses cuffs to measure arterial compliance, which is the elasticity of the artery. Their plans: include a prototype of the cosinor as an Excel spreadsheet, and they have something that almost works.


Sphygmochron Discussion - Larry Beaty

* Larry presented the text of the proposed disclaimer for the Sphygmochron that is going to be posted on Sourceforge for version control and development, on
* Franz: Want to assure that the software and the database are both adequate, possibly the software is too early. Was concerned about giving away the software.
* Larry: Phoenix should take a crack at trying to solve Franz's issue.
Chris: Placing the software on a developers site is not publishing it, merely placing it. However, anyone can download it if they know it is there.
