Area of Science:

  • Occupational Health and Safety
  • Biomedical Engineering
  • Human Factors Engineering

Background:

  • Respirator design requires integrating complex physiological data.
  • Existing frameworks for physiological data in respirator design are limited.
  • The Respirator Performance Rating Table (PRT) offers a structured approach to physiological information.

Purpose of the Study:

  • To present mask design modules relevant to respirator performance.
  • To correlate these design modules with physiological effects outlined in the PRT.
  • To provide a framework for designers integrating physiological considerations.

Main Methods:

  • Analysis of existing mask design principles.
  • Mapping design modules to specific physiological effects within the PRT.
  • Development of a conceptual model linking design and physiology.

Main Results:

  • Identification of key mask design modules.
  • Demonstration of relationships between design modules and PRT physiological effects.
  • A structured approach for considering multiple physiological effects in design.

Conclusions:

  • The presented design modules offer a practical way to utilize PRT data.
  • Integrating physiological effects early in design can improve respirator effectiveness.
  • This framework supports a holistic approach to respirator mask design.
