April 2, 2019 Blood Pressure ABSTRACT Blood pressure is recorded as the systolic and diastolic. The systolic blood pressure is the top number and it is the amount of pressure in your arteries during the contraction of your heart muscle. The diastolic blood pressure is the bottom number that is referring to the blood pressure when your heart muscle is between beats. The systolic is the maximum pressure that occurs when the heart contracts. The diastolic is the pressure when the heart rate is relaxed between contractions. In this experiment a sphygmomanometer is the instrument that was used to measure pressure. The cuff should be placed over the brachial artery, where the sensors are labelled on the instrument. In addition, a stethoscope is needed to hear the first and second Korotkoff sounds. Blood pressure is the measure of the force exerted by the blood against the walls and arteries and veins. The amount of pumping created by the heart produces this force. Normal blood pressure is considered to be anything below 120/80. Prehypertension is defined as a systolic reading between 120 and 129, diastolic reading lower than 80. Hypertension is defined as blood pressure of 130/80 or higher. MATERIALS BIOPAC Electrode Lead Set (SS2L) BIOPAC Disposable Electrodes (EL503,) 3 electrodes per subject Mat, cot or lab table and pillow for Supine position Biopac Student Lab System: BSL 4 software, MP36, MP35 or MP45 hardware Computer System (Windows 8, 7, Vista, XP, Mac OS X 10.5 – 10.8) Sphygmomanometer and Stethoscope

Rubbing alcohol and swab (to clean stethoscope earpieces and stethoscope diaphragm) Tape measure (for pulse speed calculation) METHODS 1. Turn the computer on and plug in the equipment as follows. CH 1 is BP Cuff, CH 3 is the stethoscope, CH 4 is the electrode lead set. 2. Place the three electrodes on the Subject. One on right forearm (white lead), one on the right leg (black lead), and one on the left leg (red lead). 3. Open the cuff valve and roll the cuff in on itself to release all the pressure. Start he Biopac Student Lab. 4. Calibrate by inflating the cuff to 160 mmHg.The deflate the cuff to 40 mmHg and tap the stethoscope twice. 5. Left arm sitting up, the director should inflate the cuff to 160 mmHg and release the pressure at a rate of 2 to 3 mmHg/second and call out when the Korotkoff sounds first appear. Director should continue to listen and call out when the pressure sounds completely disappear. Perform this twice as segment 1-2. 6. Right arm sitting up, the director should inflate the cuff to 160 mmHg and release the pressure at a rate of 2 to 3 mmHg/second and call out when the Korotkoff sounds first appear. Director should continue to listen and call out when the pressure sounds completely disappear. Perform this twice as segment 3-4.

    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.
