Area of Science:

  • Occupational health and safety
  • Biomedical engineering
  • Human factors engineering

Background:

  • Respirator mask design is complex, limiting direct incorporation of physiological data.
  • Physiological information is typically collected post-design during mask evaluation.
  • Computer-aided design (CAD) is the ultimate goal for respirator development.

Purpose of the Study:

  • To develop a method for integrating physiological knowledge into respirator mask design.
  • To create a framework for translating physiological data into design parameters.
  • To advance the use of computer-aided design in respirator development.

Main Methods:

  • Literature review to gather best estimates of physiological data.
  • Development of a Performance Rating Table (PRT) to organize this data.
  • Structuring physiological knowledge for design application.

Main Results:

  • The Performance Rating Table (PRT) was created.
  • The PRT organizes physiological knowledge by mask type and workload.
  • It provides performance data based on literature estimates.

Conclusions:

  • The PRT represents a foundational step towards formulating usable physiological knowledge for respirator mask design.
  • This approach facilitates the integration of physiological factors earlier in the design process.
  • It supports the development of more effective, physiologically informed respirator designs.
