The purpose of this project is to develop a low-resistance breath condensate system that can handle the very high ventilations of human exercise, develop a system that allows for simultaneous exhaled gas and condensate collection during exercise, and validate the system to correct for dilution of the respiratory solutes in the expired condensate.
At this time, we have met with our client twice and spent most of our time thus far researching pre-existing breath condensate collection systems for use at rest. We are beginning to brainstorm and formulate our own ideas for a system that will work during exercise. (last updated 2/16/03)
| Week | Reporting Period Beginning | Activities |
|---|---|---|
| 1 | January 24 | Formed a team, assigned roles on the team, and scheduled a client meeting. |
| 2 | January 31 | Met with the client and learned the background of the project and obtained several papers to read regarding breath condensate systems. |
| 3 | February 7 | Read through the papers provided by the client, formed a rough draft of the PDS, and began to do our own individual research. |
| 4 | February 14 | Had a second client meeting where we presented our most preliminary ideas and asked questions about areas of the PDS we were unsure of, continued reasearching, and started brainstorming. |
| 5 | February 21 | Spent the week individually brainstorming, then regrouped as a team and organized our possible design ideas, and revised the PDS. We are beginning to prepare for the midsemester presentation and paper. |
| 6 | February 28 | Met with the client and present our design ideas, received feedback, and saw the Jaeger exhaled breath condensate system. |
| 7 | March 7 | Revised and compiled our ideas into five desings, created a PowerPoint presentation including sketches of each desgin and a decison matrix, and gave the presentation Friday. |
| 8 | March 14 | Divided the mid-semester paper into individual parts, and then compiled those parts into the paper turned in on Friday. Also discussed tasks to complete over spring break. |
| 9 | March 21 | Spring Break |
| 10 | March 28 | Completed an AutoCad drawing of the V-shaped tube, met with Bill Hagquist and determined copper to be the best material to make the tube out of, purchased heating tape from Home Depot, and obtained student shop work permits. |
| 11 | April 4 | Had the V-shaped tube soldered together, drilled a hole in the apex of the V-shaped tube and the cap to the collection vial, and determined a heating tape to order from Lesker Co. since the product purchased at Home Depot would not work for our application. |
| 12 | April 11 | Prepared the V-shaped tube for testing by cleaning it out, gluing the collection vial cap onto the apex of the V-shaped tube, attached foam tape to the ends of the V-shaped tube to seal it to the existing air tubes, and purchasing heating pads in place of heating tape to heat the exhaled air tube. We also determined a time to test the prototype in the client’s lab. |
| 13 | April 18 | The device was tested as part of the current exercise air analysis system and performed as expected with only minor problems. We began working on the final poster presentation and determined the future plans for the project. |
| 14 | April 25 | The end-of-semester poster presentation was completed and a short presentation given in front of the clients and advisors. We then began working on the final paper. |
| 15 | May 2 | The final paper was completed and turned in to our advisor along with design notebooks and peer evaluations. We also had a final meeting with our advisor for the semester and set goals for what should be accomplished over the summer before the start of fall semester on the project. |
