Overview

• There is no means of rapidly cooling pediatric
  and neonatal ECMO patients.
• Cooling offers a way to provide neurological
  protection for the patient.
• Solution A cooling unit that will work in
  conjunction with pediatric and neonatal ECMO
  circuits
• Current Design Possibilities
• Cooling block
• Cooling sleeve

3
Next Semester Project Goals

• High-level timing goals
• January choose design and start
• modeling
• February complete computer modeling
• analysis
• March research means of building
• cooling unit

  safety
• Patient temperature sensors
• Ensure proper cooling
• Benefits
• Inducing hypothermia when desirable
• Integration into ECMO circuit
• Limits amount of new equipment and pick and
  choose when to use it
