1. The takeaways from the reality check

2. The project's initial FMEA (start by identifying the critical failure modes)

3. Additional interviews transcripts

This week, our group focused on determining which aspects of the project we would include in the works-like prototype, as well as coming up with a parts list for the prototype. Additionally, we started thinking about the project's FMEA (Failure Mode and Effects Analysis).

1. Takeaways from the reality check

Our meeting with Professor Cabodi was very productive. The key takeaways were as follows:

• We are on track and are in a good position to move forward toward our works-like prototype

• We will choose two measurable parameters (Pulse-Oximeter and one other) to focus on for our works-like prototype

• Demonstrate that we can measure different parameters and write a rudimentary algorithm that shows how changing parameters will effect the device

• Create a parts list with a link to each part

• Be sure to emphasize in DRIII that our device is intended to assist anesthesiologists rather than replace them

2. Initial FMEA

For our project's FMEA, we began by identifying some of the device's critical failure modes. The following is an incomplete list of potential critical failure modes:

1. Failure to properly place and secure sensors

2. Sensor failure

3. Algorithm failure

4. Device's warning is not noticed by attending physicians

5. Device cannot be or is not properly cleaned/disinfected/sterilized

6. Failure to adequately account for contraindicators

7. Surgery environment causes device failure (fluid short circuits electronics, electromagnetic interference, etc.)

These potential failure modes will serve as an initial starting point for our project's FMEA, and will be expanded upon as we move forward.

3. Additional Interview Transcripts

No additional transcripts to include at this time.
