  1. Quad Rat Vitals Monitor Client: Dr. Alex Converse Advisor: Dr. Tom Yen Team: Jack Ho Nathan Werbeckes Joseph Yuen Guest Starring: KuyaTakami

  2. Problem Statement • Vitals for anesthetized rats during PET imaging • Heart rate (200-500 bpm) • Rectal temperature (93 – 100° F) • Respiration rate (20-30 bpm) • Current oximeter is designed for “small animals” • Inaccurate at faster heart rates • Current devices too expensive • Budget = $4,000 USD Problem Statement : Background Info : Design : Future Work Jack Ho Team Leader

  3. Rat Rat Rat Rat Quad Adjustable Isoflurane Delivery* Isoflurane O2 Problem Statement : Background Info : Design : Future Work Jack Ho Team Leader *Slide by Dr. Alex Converse

  4. Current Devices • Veterinary Oximeters • Nonin, Bionet, etc. • Starr Life Sciences • MouseOx • Expensive Problem Statement : Background Info : Design : FutureWork Jack Ho Team Leader

  5. Last Semester’s Final Design • Decided to buy sensors (FSR, pulse-ox, thermistor) • Design and build circuit elements • Integrate and display with LabVIEW Problem Statement : Background Info :Design : Future Work Nate Werbeckes Communicator

  6. Final Design Heart Rate Computer LabView DAq Box Temperature Respiratory Rate Blood Oxygen Level Problem Statement : Background Info :Design : Future Work Nate Werbeckes Communicator

  7. Heart Rate • Pulse-Ox clip • Transimpedance, differential, & non-inverting amp • Process with peak detection algorithm • Display in LabVIEW • Working on: peak detection accuracy DESIGN:Heart Rate : Temperature: Breathing Rate Nate Werbeckes Communicator

  8. Temperature • Oral Thermometer from Walgreen's • Voltage divider & non-inverting amp • Heat-shrinking plastic • Display and integrate in LabVIEW • It works! DESIGN: Heart Rate : Temperature : Breathing Rate Joseph Yuen BSAC & BWIG

  9. Breathing Rate • Force Sensing Resistor (FSR) • Voltage divider • Place underneath rat • Display and integrate with LabVIEW • Needs to be tested DESIGN: Heart Rate :Temperature: Breathing Rate Joseph Yuen BSAC & BWIG

  10. Future Work • Test FSR breathing rate monitor with rat • Choose most accurate peak detection algorithm • Integrate and display all information in LabVIEW • Create full scale model for four rats simultaneously Problem Statement : Background Info : Design : Future Work Joseph Yuen BSAC & BWIG
