About this Course

Ozone and Your Patients' Health
Clinical Scenarios

The Clinical Scenarios section of this course discusses the following scenario and others in detail.

A 12-year-old girl and her mother arrive at your office for an evaluation of the child's asthma. At soccer practice the girl experienced chest tightness and shortness of breath, and she woke up during the night wheezing. Yesterday was a Code Red air quality day for ozone. The mother asks, "Do you think ozone caused her wheezing? Should I make her skip practice on Code Red ozone days?"

During the summer months, millions of people in the United States are exposed to the ambient air pollutant ozone at levels that can cause uncomfortable but reversible respiratory symptoms as well as a number of more serious health effects. Ozone and Your Patients' Health is a short, evidence-based training course that:

  • Describes the physiological mechanisms responsible for the lung function changes and symptoms caused by exposure to ground-level ozone
  • Describes the relationships observed between ground-level ozone and other adverse health effects
  • Discusses in detail the effects of ozone exposure on patients with asthma
  • Helps health care providers advise their patients about exposure to ozone
  • Provides practical Patient Education Tools to help patients understand what triggers their symptoms and how to alleviate them

Ozone and Your Patients' Health is designed for family practice doctors, pediatricians, nurse practitioners, asthma educators, and other medical professionals who counsel patients about asthma, air pollution, or exercise. Patients and their families may also use this material to learn the science behind ozone’s effect on respiration and how to manage their respiratory health using the Air Quality Index.

Course Objectives

Upon completion of this course, you will be able to:

  1. Describe how ozone is formed and where it is found
  2. Identify the effects that exposure to ozone has on the general population
  3. List the different effects of ozone at varying exposure concentrations and durations
  4. Identify the effects that ozone has on asthma patients
  5. Explain the purpose and use of the Air Quality Index
  6. Identify common sources of information about the Air Quality Index
  7. Address typical patient questions and clinical scenarios relating to ozone exposure
