In this experiment, students will become familiar with auscultation of blood pressure. In addition, students will use the PowerLab to measure systolic blood pressure. Students will examine the changes in peripheral circulation during blood pressure measurement and compare measurements of blood pressure made in different parts of the body.

Document Color Coding Scheme
Throughout the experiments, certain words are printed in color. These words are in reference to topic entries in the StudentQuick Reference Guide (available from your local ADInstruments representative). References to acquisition settings are in blue, analysis topics are in green and troubleshooting tips are in red. By informing your students that this resource is available to them, you can encourage students to guide themselves and improve their understanding of the software.
There may beinstances when you want to modify the experimental protocols for your students. In addition to the Acrobat (.pdf) files, the protocols are available in Word document (.doc) format. Feel free to make modifications as you see fit to tailor this experiment to the needs of your classroom laboratory.

This experiment is often best performed in groups of three or more. Successful planning and division of labor will enable all the experiments to be easily performed in a timely manner.
Suggestions for groups:
• One student is the volunteer.
• The second student auscultates blood pressure.
• The third student...
