* Chris: Been working on requirement use cases.
* Larry: Assessing resources at the lab.
* Dick: Been working with Germaine on the database, specifically
command line scripts, and working on interface description, specifically
between sensor and processor, and am considering USB and analog
vs. digital.
* Gerry: Clinical information systems knowledge area and needs.
* Bob: working on the functional requirements of the prototype,
especially beat-to-beat heart rate and blood
The Professional Identity Blues
What is Electrical Engineering?
* What Problems does it solve
* What issues were not previously solvable?
* What issues were not previously recognized?
* How important/Necessary is this Expertise?
What is Cardiology?
What is Clinical Informatics?
Why are organizations advertising for Directors of Clinical Informatics
but require no formal education in clinical informatics.
Dealing with information in support of clinical care. Perhaps
there is no awareness of its value.
Organizations continue to conduct projects on medical informatics
and typically the outcomes are not considered acceptable because
a lot of money is spent and the outcomes are not considered useful,
but often decrease the value of the informatics.
Use cases and gaping holes.
* Wearer signals the device to log an event
- Assures data-acquisition logic despite sensor failure.
* Technical confirm device functions.
* Technician confirms data acquisition.
* Technician connects device to wearer
* System collects data
* Wearer confirms device is work
* Wearer restarts data collection.
* Technician downloads data to a file.
Wearer Signals Device to Log Event
1. Wearer pushes button
2. System activates status light
3. System logs button down.
4. Wearer observes stratus light.
5. Wearer may pause.
6. Wearer releases button.
7. System logs button-up
8. System de-activates status light.
9. Wearer may pause.
10. Wearer repeats sequence according to predefined code.
Technician Confirms Device Functions
Confirms Data Acquisition.
* Status light
Technician Downloads Data to File
* Status light pattern.
- Start
- Continuation
- Completion
Algorithms
* Waveform peak
* Waveform trough
'* Heart Rate
* Systolic BP
* Diastolic BP
Remaining questions:
* Power management: how to determine if there is sufficient power:
Dick will recommend whether there is sufficient value in learning
about this from the prototype and what behavior is to be observed.
* Data Acquisition: how confirm to it is making a measurement.
Can an on-off switch and an on-off light provide sufficient information
and is it easy to do this.
