Essay about Lab Report: Blood Pressure

The purpose of arterial pressure and the pulse lab is to determine the effect of posture and exercise on systolic and diastolic pressure and the heart rate. And also in order to find the differences in the reading taken under these condition compares to the baseline reading. The Sphygmomanometer and stethoscope are used to measure the systolic and diastolic blood pressure, counting the beat on the radial artery will give the reading for pulse rate and by using the lab scribe software and IWX214, the blood pressure will be measured. In the heart, the aorta and the carotid arteries have baroreceptors and the chemoreceptors that identify the changes in arterial pressure and the changes in

Nearly 100,000 beats per day, or about 37 million beats per year; most of the time you are unaware that your heart does this (“WebMD”). The question is, what is the difference between your resting heart rate, compared to your scared heart rate. For the age group tested (12-16 year olds) their healthy heart rates could vary between 70 and 100 beats per minute. The importance of this project is knowing if you are “pushing” yourself too hard, and to know if certain things trigger unhealthy problems, like horror movies. The hypothesis stated is, if you scare a person from a resting heart rate to a scared heart rate their heart rate will increase because adrenaline is released into the blood.

Going from supine to standing position induced changes in the hydrostatic pressure experienced by the superior and inferior regions of the body. As tilt occurred blood began to pool in highly distensible veins of the lower region. Because of this pooling phenomena there was an expected reduction in venous return to the heart and subsequently a reduced CO (Fig. 5) as seen 30 seconds post-tilt (Sherwood, 2013). This reduced CO exemplifies the Frank-Starling Law of the Heart which states that reduced venous return will result in reduced CO by the heart (Sherwood, 2013). The Frank-Starling Law can also explain lowered SV as seen in Figure 4. The only explanation to why CO (a product of HR and SV) might have increased in this experiment immediately after tilt was because HR (Fig. 1) significantly increased at the same time in comparison to the small decrease in SV as seen in Figure 4. MAP and BP decreases were

As the procedure shows this experiment was to learn about the different types of blood pressure and how music affects blood pressure. Participant one’s average blood pressure without music was 106/70 and increased to 112/72 while listening to rap music, decreased to 105/63 while listening to country music and decreased to 106/62 while listening to jazz music. Then, participant two’s average blood pressure without music appears to be 104/72 and was increased to 106/75 while listening to rap music, decreased to 101/62 while listening to country music, and decreased to 94/61 while listening to jazz music. Then, participant three’s average blood pressure without music is 112/66 and increased to 117/70 while listening to rap, decreased to 110/64 listening to country and decreased to 107/62 while listening to jazz music. Participant four’s average blood pressure was 131/77 and increased to 135/78 while listening to rap music, decreased to 128/75 while listening to country music, and decreased to 123/72 while listening to jazz music. Participant five’s average blood pressure was 124/77 and while listening to rap music the participants blood pressure

Unit D: Human Systems in Biology 20 is one of the main sections that becomes relatable to the Program of Studies (POS) for the Heart Rate and Exercise LabQuest activity. General Outcome #2 focuses on how students will explain the role of the circulatory systems and defense systems in maintaining an internal equilibrium. This further goes into measuring the students level of understanding the concepts of heart rate and the factors that affect it (Alberta Education, p. 41). Heart rate can then branch out into concepts of maximum heart rate, resting heart rate and recovery time. Through the LabQuest experiment, the main affecting factor was exercise and how that relates back to the fitness level of an individual [20-D2.3s]. Other key concepts found in the lab’s analysis questions then dealt with disorders of the heart [20–D2. 2sts]. Students are additionally "conducting investigations into relationships between and among observable variables" through the use of tools to gather information in regards to their heart rates [20–D2.2s]. Through group work activities, they are achieving collaborative work in measuring heart rate and other factors relating to the circulatory system [20-D2.4s]. To analyze and interpret, the POS explicitly states that students have the option in determining, from available data, the relationship between blood pressure and exercise [20–D2.3s a]. For the simulation, predominantly at the high school level, the

Ambulatory blood pressure (ABP) monitoring and ambulatory heart rate recording are regarded as the standard methods for the diagnosis and prediction of cardiovascular disease [1,2]. It has been reported that a non-dipping pattern of heart rate is strongly associated with increased risk of all mortality in epidemiological settings [3,4]. In addition, there are many recent reports on the clinical significance of ambulatory blood pressure. A non-dipping pattern and nocturnal hypertension are associated with increased cardiovascular morbidity and mortality [5]. On this basis, we raised some questions. Are there any relationship between HR dip and BP dip? The non-dipping situation expressed on what kind of patients? What can they predict?

In this scenario, the subjected data is chest palpitation, lightheadedness and dizziness, the objective data is elevated heart rate with irregular rhythm, orthostatic blood pressure readings, lying 135/90, sitting 120/80, standing 100/60, and the client becoming dizzy and light-headed as he moves from a sitting to a standing position while taking the blood pressure. The subjective and objective data indicates that the patient has orthostatic hypotension. To determine what is causing the orthostatic hypotension a more in-depth health history, physical assessment, labs and diagnostic testing would need to be done.

Results from the experiment can be found below in table 2. As apparent in the table, with an increase in the intensity of the exercise, the heart rate and blood pressure both increased. An important observation from the data is that the systolic blood pressure steadily increased as we increased the intensity. However, the diastolic blood pressure remained relatively constant as the intensity of the exercise increased. The heart rate steadily increased with the increase of intensity as well.

The purpose of lab six, is demonstrate how different activities like exercise, postural changes, and cognitive thinking change arterial pressure as well as heart rate. Blood pressure, which is abbreviated as BP is the force that is placed onto vessel walls by the blood that it contains. In healthy individuals, BP should be 120/80 mmHg, but recent research has shown that healthy individuals BP should be lower than 120/80 mmHg. The first number, in this case 120 is known as the systolic number. The systolic number is known as the amount of pressure placed onto the vessel wall by blood during ventricular contraction. When someone is taking another persons blood pressure, this is the first sound that the person will hear. This is because the blood vessel opened up enough to allow blood to begin passing through. The second number, 80 represents the diastolic number. The diastolic number represents when the vessel is relaxing and blood is getting through without any extra force. Also, this number is represented by the last sound an individual hears in their stethoscope. Aside from BP, heart rate also known as pulse rate, is the number of times a persons heart beats in a minute. (Marieb & Hoehn, 2014, pp. 708-710).

Figure 1 shows that the systolic and diastolic pressure while the subject was sitting down, 119/64, is lower than that of the other body positions and exercise. Standing showed the second lowest systolic and diastolic pressure, 121/83. Lying down showed a slightly higher blood pressure of 123/84. The highest blood pressure, 133/94, was measured when the subject had just completed some physical activity. Figure 2 and 3 display, respectively, the difference between heart contractions at rest and after exercise, as illustrated by the greater number of contractions following exercise in the same amount of time compared to resting conditions. In addition to displaying the interval lengths for three sequential beats from Figures 2 and 3, Table 1 also includes the heart rate for before and post exercise, 102 bpm and 132 bpm, respectively. Figure 4 shows similar

and pumps a greater volume of blood. This will increase blood pressure (BP) so that you avoid fainting. (2) The valves in

In our practice, as the pressure in the cuff is adjusted to fall gradually from above systolic, no sound is heard. Note the pressure at which the first 'tapping' sound is heard. This is the systolic pressure. As the pressure in the bag is reduced further the sound first becomes quieter, then changes to a louder tapping. With further decreases in pressure, the sound changes again from a tapping sound to a blowing noise. The pressure at which this change occurs recorded as the diastolic pressure. Further reduction in cuff pressure leads to the total disappearance of any sound. Posture change definitely affect both arterial blood pressure and pulse rate. After standing for several minutes we obtained 121/84 mm hg for blood pressure and 100 pulse/min for pulse. After reclining for 1 minute, the result come out as expected that both arterial pressure and pulse rate decrease to 120/69 mm Hg with 102 pulse/min.

Monitor for decrease in blood pressure and an increase in pulse rate (Durham & Chapman, 2014)

The purpose of these lab exercises is to understand the function and importance of an electrocardiogram. This lab will demonstrate how stress levels or different elevations can affect human heart rate. Furthermore, the equipment used in the experiment will show the functions in the right and left arm; as well as, in the right and left ankles. Finally, the lab will serve a purpose as a way to know how to read an electrocardiogram and calculate the heart rate.
