Wayne Hosley's 10-minute talk from the UXPA Boston 2015 Conference

1. Changing a Life: Impactful Designs for
Sick Children
Presenter: Wayne Hosley

2. Introduction
For small children with respiratory complications, improper tools have become an increasing problem.
Children with certain illnesses are provided a respiratory mask that is supposed to be a life-saving
device, but in some cases can cause serious health problems such as pressure ulcers.
Statistics
• In the medical field, only 6% of healthcare dollars are allocated for pediatric patients, which means
the quality of the devices clinicians use are not the best.
• In fact, 27% of all acutely ill infant patients develop pressure ulcers. It has been estimated that
medical devices are the cause of over half those patients developing the ulcers (Murray, Noonan,
Quigley & Curley, 2013).

3. Goal: Redesign the C-PAP Respiratory
Mask
The focus of our project is primarily on:
• Headgear Attachment

4. What is C-PAP?
CPAP: Continuous Positive Airway Pressure
• Increases air pressure in your throat
• prevents airway collapse
Used for:
• sleep apnea
• infants whose lungs have not fully developed
• children with illnesses that affect breathing

6. Current Problems
• No universal fit / comfort
• Strapping complications
• Pressure Ulcers
• Loss of suction over time
• Cost

7. Data Collection – Overview
Literature Review (articles, books and patents)
• Info on design and operation of respiratory mask
Expert/User Review
• Hands-on experience at hospitals
Competitive Analysis
• Pros and cons of different masks
Forms of Design Innovation and Usability Testing
• Methods used to identify what features should be included
in the redesign

8. Identifying User Needs: Clinicians
and RT’s
• Problem areas include the bridge of nose and
jaw/chin
• Replaceable/cost-effective
• Attach and detach easily
• Patients DO NOT LIKE
– needs to be as unobtrusive as possible.

9. Findings from Clinicians and RT’s
• Prefer spandex-covered strap material
• Quick assembly for attachment pieces
• Indication of tightness
• Don’t want to constantly adjust for
proper fit
• No hard material touching skin

10. Initial Concepts for Redesign
Components:
• The headgear
• Attachment Ideology
• Materials
