Hello, I'm Dr. Robert Kolak, co-chair of the Medical Committee of the Virginia Healthy Pathways Coalition, one of the sponsors of this teaching tool. The video you're about to see is another component of the toolkit, blood pressure measure. in the 21st century. When measuring blood pressure, a stethoscope is placed over an artery that has been occluded by an inflated blood pressure cuff. The series of sounds that you hear through that stethoscope as you slowly deflate the stethoscope the cup are called the Korotkov sounds.
Korotkov sounds are divided into five phases. The pressure noted at the beginning of the first phase, called tapping, denotes the systolic blood pressure. The pressure noted at the fifth or last phase, when the sounds disappear, corresponds to the diastolic level.
This training is intended to help you correctly identify the systolic and diastolic blood pressures. It also will demonstrate the recommended rate of deflation that should be used when measuring blood pressure. This video contains 10 examples of blood pressure readings, 5 using an aneroid manometer and 5 using a mercury instrument. As you watch the mercury or needle on the aneroid fall and hear the Korotkoff sounds for each example, record the systolic and diastolic pressures you observe.
The correct answers will appear at the end of the video. This program was produced by the University of Michigan. produced in cooperation with the following partners. The Heart Disease and Stroke Prevention Project at the Virginia Department of Health, Sentara Healthcare, Virginia Healthy Pathways Coalition, Cardionics Incorporated, the Chesterfield County Health Department, and the Virginia Information Technologies Agency. We hope that you will find this information useful.
Thank you. Thank Thank you. Thank you for watching.
