Project Overview
• Continuous Positive
Air Pressure (CPAP)
breathing apparatus
• Assists respiration by
forcing air at a
pressure ranging
from 4-8 cmH2O
• Primarily used for
infant respiratory
distress
CPAP Administration
• Polin and Shani (2002)
Problem
• Nosepiece pressure causes injuries to the delicate skin of the
nasal area.
–
–
–
–
Ulceration and contusion
Tissue necrosis
Nasal flaring
Nasal snubbing
Objectives
• Analyze the applied force of the device on the nasal
area.
• Propose new device

Work Completed
• Obtained device
• Researched similar designs
• Developed soft gel model representing
premature infant face to replicate delicate infant
skin
Current Work
• Continued modification of pressure sensitive materials for the
representation of an infant face.
– Clay
– Soft gel
• Looking for more realistic infant doll
Future Work
• February 2004
– Design changes to current device
– Model of prototype
• March
– Development of prototype
• Design of functional model, if possible
• April
– Compile and present design poster and final results
