Objective: Define the terminology needed for measuring blood pressure. Blood pressure: the force that blood exerts against the walls of a vessel. Systolic pressure: the maximum pressure exerted against the walls of the artery during ventricular contraction. Diastolic pressure: the lowest pressure exerted against the walls of the artery during ventricular relaxation.

Pulse pressure = systolic pressure – diastolic pressure Mean arterial pressure (MAP) = diastolic pressure + 1/3 pulse pressure, this is an average of the pressure that is actually moving blood through the arteries. Sphygmomanometer: an inflatable cuff that is attached to a pressure gauge that is capable of measuring arterial blood pressure.

This diagram shows variation of blood velocity and blood pressure as it flows through the blood vessels. After looking at this diagram, why do you think blood pressure is measured in the arteries as opposed to other blood vessels? Campbell

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
