BLOOD PRESSURE EXPERIMENT Ryan Williams Lab Partner: Joseph Parrish 12/7/12 Abstract: The purpose for the report is to record data and explain key information in the blood pressure experiment performed. To perform the experiment the components used were; Sphygmomanometer, a stethoscope, a computer, and a pencil and paper. The procedure used for this experiment was one person's blood pressure was recorded while resting and then it was recorded while they were active, the results were then recorded in graph form so that the person could see their blood pressure. There were three trials for this experiment. The results of the experiment were for the resting trails, trial 1: 142 systolic pressure over 61 diastolic pressure. The rest of the recordings will be systolic over diastolic pressure. Trial 2: 146 over 71 and trial 3 was 160 over 59. For the active part of the experiment the results were again recorded systolic over diastolic pressure. For trial 1 it was 108 over 46, trial 2 was 118 over 57 and finally trail 3 was 131 over 61. Background: The reason for this experiment is because in class we are in a unit directly related to the heart. We have been studying the heart's specific functions and what the specific parts of the heart do. This has all been related to the overall topic of Anna Garcia, whose mysterious death is what we are trying to debunk. This lesson on the heart is related to Anna because it is believed that she had a history in the family of heart conditions and high cholesterol. We are measuring the systolic and diastolic pressure which in turn gives us someone's blood pressure. High blood pressure leads to heart problems and high cholesterol. We performed this experiment to practice using an sphygmomanometer. We did this so we could formulate a basic understanding of what a doctor would do to analyze and determine if Anna Garcia had high cholesterol. We are understanding more about the heart and its functions, and also more about the tools and equipment that are used to analyze and examine the heart. Hypothesis: If one has been active for a period of time, then one's heart rate will increase. Materials and Methods: The materials that were used to complete this experiment were as follows: · Computer with Vernier Logger Pro software, Vernier LabQuest Mini with USB cable, Vernier Blood Pressure Sensor, Logger Pro resource sheet, Sphygmomanometer, Stethoscope, timer, Laboratory Journal, Experimental Design resource sheet, pencil, and paper. Open logger Pro, then open the LabQuest mini and attach it to the computer using the USB cable. Then open the blood pressure document to record electronic blood pressure. A student will then attach the sphygmomanometer to another's arm and then put the stethoscope under the sphygmomanometer and then record the students blood pressure. This will be done in three resting intervals then the graphs will be recorded and saved. Next the student will perform activities that will increase their heart rate and then the student will measure the other student's heart rate and record it, same as the resting period. Once the graphs are recorded and the systolic, diastolic, mean, and pulse are recorded the students can put away the materials and begin writing a lab report. Results: The results for me while resting were as follows on the graph. While I was resting my heart rate and blood pressure seemed to be at a normal pace . Ryan Resting This is the records of me after I had completed each of the instructed jogging regimens. My blood pressure once again seems pretty normal for the given information, decreasing at a normal and slight pace. Ryan After Jogging Discussion: To discuss the record of me resting. My heart rate was varied and took about the same time to record. My systolic pressure was a little high for each of the trials while my diastolic pressure was about where it should be. This makes me think that something went a little haywire in the experimental process. I seem to have a normal blood pressure level while resting. My systolic pressure was about ten to fifteen over what it should have been. To discuss the records after I had completed each of the instructed jogging regimens. My blood pressure once again seems pretty normal for the given information, but all of the trials may not have been accurate. My blood pressure seems normal for the most part but might not be due to the lack of credibility in the trials. Conclusion: My blood pressure increased after my jogging regimens, then it did while I was resting.
