[027] BOARD REVIEW SESSION 3: PRESSURE AND PHYSICAL EFFECTS OF THE BIOSPHERE THAT YOU NEED TO KNOW FOR AEROSPACE MEDICINE BOARD REVIEW

摘要

PROBLEM STATEMENT: In order to pass the Aerospace Medicine Board Exams you need to be familiar with the pressure and physical effects of the biosphere. This presentation is in support of the Aerospace Medicine Board Review section. TOPIC:This presentation will be on the Biosphere and describe the pressure and physical effects. The presentation will cover the characteristics of the atmosphere, such as humidity, temperature, and density; the structure of the atmosphere: troposphere, stratosphere, mesosphere, and thermosphere.The gas laws will be presented: Boyle's Law, Charles'Law, General Gas Law, Dalton's Law and Henry's Law. Examples of the application and implication of the gas laws to aerospace medicine will be presented. The biospheric properties of the atmosphere will be described such as composition of oxygen in the atmosphere, pressure changes in the atmosphere, and space-equivalent regions.The pressure environment will be described based on physiologic zones: physiologic zone, physiologically deficient zone, the space-equivalent zone, and space. Advantages and disadvantages of pressurization will be presented.
