Phoenix Ambulatory Blood Pressure Monitor Project
3/9/2008 Meeting Notes



* Larry: 1) reading Wade Peterson's document: Creation of Interoperable Circuits using Clean Room Techniques, 2) developing a sample 510K exercise submission as part of a course on Medical Quality Systems and will share the results with us in May or June, 3) would like to work on a "daily Sphygmochron" application for the Halberg Chronology Center.
* Chris: developed several categories of scenarios of the Phoenix Monitor requirements.
* Gerry Werth: using a recent publication of the State of Minnesota Health Informatics, he and Gary Berasik are working on migrating Sifert's "Health and Disease Questionaire" from a proprietary system to an open website, as pilot project to build his team for the open source Clinical Care Support System. Expects to have progress to report on April 27, two meeting from now.


Usage Scenarios by Chris Adams

Chris introduced the phrase: "Activity of Daily Living" in slide 14 as an alternative to "Wearable".
* Wearable
- Suitable for wear or able to be worn on the body
* Activity of daily living (ADL)
- the things a person normally does in daily living including any daily activity performed for self-care (such as feeding, bathing, dressing, grooming), work, homemaking, and leisure
- health professionals routinely refer to the ability or inability to perform ADLs as a measurement of the functional status of a person
- See

He discussed the following 9 scenarios:
1. Internet-based individual health surveillance
2. Home-based self care
3. Clinical care
4. Self-care followed by clinical care
5. Public healthcare
6. Research
7. Sports training
8. Emergency medical service
9. Combat lifesaving

Germaine and Franz suggested that #8 Emergency Medical Service was not a blood pressure chronobiology application but rather post-event applications of continuous monitoring.

* Bob: Suggested three techniques that may increase our ability to measure blood pressure with the peizofilm technique: using 1) "piezofilm as part of a chest band to sense blood pressure in the aorta where the vibration is greatest, 2) larger sensors rather than smaller sensors (i.e. six times larger in linear length to capture perhaps 36 times more energy, and 3) measuring blood pressure on female breasts that may be physically more responsive to blood flow cycle within a blood pressure measurement.
