This is a closed book exam. You may use a calculator. Only work shown in the space provided will be graded. Partial credit will be given when warranted. The exam is worth a total of 100 points. Instructor: Mark Saltzman Department of Biomedical Engineering Yale University 1 Question 1. (20 points) Cardiovascular physiology As you know from our section meeting, blood pressure is measured using an inflatable cuff and a stethoscope. Describe how this blood pressure measurement works by answering the following questions: a) What happens in your arm as the inflatable cuff is pressurized?
