I feel your HR and BP does fluctuate depending on the position you are in and the activity you are doing. Methods In this section of the lab we worked in pairs. The materials that were used were stops watch (from a phone) a stethoscope, and a sphygmomanometer. Each person in the group recorded their own pulse using the radial and carotid arteries in the body. This was obtained using the tip of your index finger and your middle finger. DO NOT USE YOUR THUMB, it has a pulse and you do not want to get that confused with your radial or carotid artery pulse. You will do a pulse check for one minute and record the results. You will do a pulse check for 10 seconds and multiply that by 6 and record your results. Then you will do a 6 second pulse and multiply that by 10 and record your results. To obtain your blood pressure we used a stethoscope and a sphygmomanometer. You are to wrap the deflated cuff around the arm so that the arrow lines up with the antecubital space over the brachial artery. The stethoscope should be applied firmly so that there is virtually no space between it and your skin (on antecubital artery). Now that the materials are into place you should raise the pressure in the cuff to about 180mm HG. Then you should start to release the valve at a rate of 2-3 mm Hg per second. This is a very crucial part!

First you will hear a tapping noise that will increase in volume, then a swishing sound, followed by a louder swishing noise, then a soft murmur, finally, all noise will cease. The first noise you hear for a few seconds is the systolic blood pressure. The diastolic blood pressure is the point where the crisp swishing noise turns into a muffled sound. This may take you a few times to get a reading. For a healthy individual the readings are about 120/80 mm Hg. Following this practice session two students will need to volunteer to by test subject for low intensity exercise to obtain their heart rate and blood pressure. It will be measure in a supine position following a 5 minute rest period.

    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.
