Vital Signs: Understanding What the Body Is Telling Us

Heart rate, blood pressure, respiration rate, temperature, pain. What do these vital signs tell you about your body? Learn the basic physiology underlying the vital signs and how to accurately assess them.

About The Course

The vital signs – heart rate, blood pressure, body temperature, respiration rate, and pain – communicate important information about the physiological status of the human body. In this six-week course we explore the anatomy and physiology underlying the vital signs so that you will develop a systematic, integrated understanding of how the body functions. Relevant body systems are reviewed including cardiovascular and respiratory, followed by explanations of how the function of these systems affects vital signs. We discuss normal ranges, normal variants, and the mechanisms that underlie changes in the objective measurement of vital signs. The course also includes demonstrations of appropriate techniques for measuring vital signs in yourself and others.

Frequently Asked Questions

Recommended Background

The course is designed for a broad, general audience but may be particularly interesting for lay caregivers, those considering a career as a healthcare professional, individuals working in healthcare, those with an interest in personal health and fitness, or anyone who simply wants to understand how the body functions. A foundational background in biology and chemistry is beneficial but not required.
