Design - Mask

Design

• How will restricting the airflow as the virus reduce the function of the lungs.
• How much air flow is required?
  • what is the volume, speed, pressure and duration of normal breathing?
  • what is the volume, speed, pressure and duration of a Cough?
  • what is the volume, speed, pressure and duration of a Sneeze?

How with the "extra air volume in the mask (re-breathing what you exhausted) affect "oxygen transfer in the lungs?

• What are the design criteria of approve masks?
• What are the filtering capabilities (limitations) of the HEPA filter material.
  • What criteria are we looking for?
  • What are the tradeoffs?
• What are the different face sizes configurations. How many sizes will be needed?
• How to measure, evaluate leakage.

Moulds can be made my anyone with CNC, 3D printer. Machine shops can make moulds. Can vacuum forming industry make these? Can HEPA filter people make filters to size?
