A medical device known as a venturi mask, also known as an air-entrainment mask, provides patients receiving regulated oxygen therapy with a known amount of oxygen.
What is the purpose of an air-entrainment mask?
- Concrete can be effectively shielded from thawing and freezing damage by air entrainment. It is accomplished by sparingly incorporating a surface-active ingredient into the concrete mixture.
- By doing this, a lot of tiny, closely spaced air bubbles are produced in the cured concrete.
- Air Conditioning. - Incorporate and maintain small air bubbles that are evenly dispersed throughout the paste, additive, or cement. - Increase the concrete's resilience.
- For resistance to freeze-thaw, air-entraining concrete is primarily used. When a freeze event occurs, the air voids act as pressure relief sites, allowing the water inside the concrete to freeze without causing significant internal stresses. Deicer-scaling resistance is another application in this area.
- Patients with breathing or cardiopulmonary disorders undergo examinations and interviews by respiratory therapists.
