1. Design Specification
• Our device will utilize an
adjustable arm-band design.
• We will use multiple LEDs
and detectors

2. Benefits of a Multiple LED system
• Produces more light which allows detector to
see dark spots better
• Even if the crisis occurs outside of the
emitance of the LED, our detectors can
identify a crisis

3. Technique
• We will use two pulse oximeters
• This can allow us to get a baseline reading
while simultaneously attempting to identify a
crisis
• Preliminary testing has proven this method to
be viable

4. Recreating a vaso-occlusion
• Vaso-occlusion causes less blood to reach
tissue
• We were able to slow blood flow to the
extremities using a sphygmomanometer

5. Pain scale
