LESSON OBJECTIVES After completing this lesson, you should be able to: 4-1. Identify the proper procedures for performing one-rescuer CPR on an adult. 4-2. Identify the proper procedures for performing two-rescuer CPR on an adult. 4-3. Identify the proper procedures for switching positions while performing two-rescuer CPR. 4-4. Identify the proper procedures for switching from one-rescuer CPR to two-rescuer CPR. 4-5. Identify the causes of problems associated with CPR, including severe gastric distention, and how the problems can be corrected and/or prevented. SUGGESTION After you have completed the text assignment, work the exercises at the end of this lesson before beginning the next lesson. These exercises will help you to achieve the lesson objectives.
