Phoenix Ambulatory Blood Pressure Monitor Project
9/9/2007 Meeting Notes




* Larry: Next development is the daily sphygmochron. We discussed the IRB concerns of informed consent.

Requirements in Layers - Chris Adams

Intention: to organize our requirement like the layers of an onion that so that we can components and their requirements and manage them. Jim: Is there a hierarchy. Chris: Yes, it s starts from the internals of the device and up to integration with the outside word.

* BP, HR, BF, Physical activity.
* Low cost
* Non-intrusive
* Performance: beat to beat

Can model your requirements using Object oriented modeling notations. English-> structured flow analysis -> object orientated modeling notations, packages. But no one who isn't a programmer can read it. So the requirements engineering group is going back to their roots, writing requirements in English, it still comes down to writing. Now it is an agile approach that non-technical stakeholders can read, that is usable, readable,
Requirements process has two key steps:
1. Elicitation - talking to people
2. Specification

User Noted Events
* Integration with diary.

Data Acquisition (DAQ)
Converts these signals into measurements.
- collect signal data from sensors
- collect user noted events
- Convert signal events to measurements
* Flexible framework for sensor configuration by
- Sensor technology
- Biophysics
Target measurements
* Stamp each measurement
- time
- Trustworthiness
* Subject to calibration
* Capacity
- 7 days of data
- 30 minutes between measurements.

Acquired Data Alarms
* Simple analysis of acquired data
- Compare measurement to limit
- limit may be user-specific
* Respond to limit violations
- Categorize violation
-- caution
-- warning
-- alarm
- Tag measurement
- Alert user or other subsystems.


At this point, Franz and Germaine joined us and offered to present their latest findings.

Impact of the following conditions:
- glycemic
- pre-diabetes
- chat
- dippers, non-dippers, reverse dippers.
- pre-hypertension
