Purpose:
The purpose of this program is to understand the physiologic responses to activity, in order to appropriately monitor your patients during any and all activity, as well as to ensure that your documentation reflects medical necessity of monitoring needs of patients.
Goals & Objectives:
At the completion of this lecture, the learner will be able to:
- Discuss the components of the oxygen transport system and provide clinical examples of individuals who have impairments in each of the components of the oxygen transport system;
- Discuss the factors that affect maximal oxygen consumption or maximal aerobic capacity;
- Identify 3 factors that can affect stroke volume;
- Discuss the relationship of stroke volume and heart rate to cardiac output;
- Describe normal and abnormal heart rate responses to activities and determine maximal heart rate;
- Describe normal and abnormal blood pressure responses to activities and define red flags regarding BP responses;
- Define blood pressure guidelines per the National Heart, Lung and Blood Institute and provide clinical decision-making recommendations regarding patients who present with elevated blood pressures;
- Identify medications that affect HR and BP responses and provide alternatives to measurement of intensity of exercise if taking these medications;
- Discuss additional responses to assess with exercise, including oxygen saturation, symptoms and perceived exertion, and describe normal and abnormal responses to activity;
- Compare and contrast differences in HR and BP responses with arm versus leg activities and static versus dynamic activities;
- Describe the effect of assistive devices on HR and BP responses; and
- Discuss tips on documentation of abnormal responses.
