Study Summary
Purpose: This research study seeks to determine whether surface pressures generated by elastic tourniquets used by phlebotomists during blood-draws can penetrate to deeper tissues where major arteries and nerves lie. Additionally, investigators will also determine the effects of prolonged tourniquet application on hand sensation using a controlled, reproducible force stimulus. In conjunction, the investigators will also track changes in skin surface pressures and pain levels over this prolonged tourniquet application. Hypothesis: The investigators hypothesize the use of common elastic tourniquets used for blood draws does not significantly impact sensation and will not elicit nerve or tissue damage. Technologies used: Monofilaments and Pressure Sensor
Primary Outcome
The pressure under blood draw tourniquets will be taken in Phases 1 and 2. During phase 1, the tourniquet will remain on the subject for a brief period of time (10-15 seconds) 10 times, allowing for enough time to acquire pressure measurements using the PicoPress device. The difference between Phase 1 and Phase 2 is that phase 1 will be performed with a phlebotomist, while phase 2 will be performed with one of the investigators for an extended period of time.
