In many health-care settings, the medical assistant is responsible for collecting blood specimens from patients and even performs some testing in the waived category. In order to properly collect the specimens, you will need to review the circulatory system and the function of blood. You will be introduced in this chapter to venipuncture and capillary collection procedures, and you will learn the appropriate supplies and equipment needed to perform these procedures. | 49 Electrocardiography and Pulmonary Function Testing Discuss the medical assistant's role in electrocardiography and pulmonary function testing. Explain the basic principles of electrocardiography and how it relates to the conduction system of the heart. Identify the components of an electrocardiograph and what each does. Carry out the steps necessary to obtain an ECG. Learning Outcomes Summarize exercise electrocardiography and echocardiography. Explain the procedure of Holter monitoring. Carry out the various types of pulmonary function tests. Describe the procedure for performing pulse oximetry testing. Learning Outcomes Introduction Cardiac testing Electrocardiogram Holter monitoring Stress testing Respiratory testing – pulmonary function testing To correctly perform testing on the cardiac or respiratory system, you need to review the anatomy and physiology of the heart and the respiratory system.
