Activity 4.2.2 Blood Pressure Lab Report

Ryan Williams
Lab Partner: Joseph Parrish
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.
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
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.
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.
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
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.
My blood pressure increased after my jogging regimens, then it did while I was resting.
