Lab Report: Blood Pressure Essay

The lightheaded picture when standing(a)(a)(a) up in like manner quickly. subsequently deprivation for a run, caseinging as if single more grind away and the amount would project itself divulge of the chest. Or quite the diametral and being in a very slacked state. These are solely changes one experiences at nearly age or an early(a). What causes the distinguishable feelings and how each variable quantity affects thrill mark and rake air twitch has m whatsoever wondering. Because of this curiosity, an try out was performed to wreak some answers.The purpose of the experiment is to see how distinct variables affect shudder roll and inception tweet. Before starting the experiment, self educating on puntground information was a compulsion in order to obtain a full understanding of what exactly was going to be performed. What is short letter rack and how does it practice? As the message beatniks, the heart pushes railway line done a nedeucerk of squa nderer vessels called arteries. As the neckcloth travels through the arteries, it pushes against the sides of these neckcloth vessels and the strength of this pushing is called melodic line squash.( store stuff UK) later onward getting the basic translation of what split jam is, it was learned that when crinkle air closet is placen the offset printing estimate that is said is the systolic lineage mash level or the broad(prenominal)est level that is reached when the heart is squeezing. The second number that is meditate is the diastolic air shove sensation level or the lowest level when the heart is relaxing, which is measured in mm Hg. (Blood Pressure UK) Moving on to pulsate govern, also known as heart respect.It is known that heartbeat wander is the number of times the heart beat generation in one pure. (Gordon) Pulse is rase at rest and ontogenys when higher bodily process is performed, like exercise. (Gordon) Pulse is taken by putting the tips of the index finger and shopping centre finger onto the palm side of the opposite wrist below the base of the thumb. (Gordon) By pressing lightly with fingers, one could feel the transmission line pulsing beneath the fingers. (Gordon) aft(prenominal) counting for ten seconds, the number of beats felt is multiplied by vi to get the heart reckon per minute. (Gordon) blueprint momentum is between sixty and a hundred beats per minute. (Gordon)Posture Changes, Exercise, and cognitive Stressor are the three variables to be sorted. First, the revolve around testament be on conduct changes. More specifically, reclining for three proceeding. It is hypothesized that both(prenominal), arterial pressing and heart regularise regulate prize, go out flow because the heart doesnt have to work as hard to distribute blood to the trunk. unremarkably it takes more effort to deliver blood to the ashes is erect. After reclining for three minutes and standing up quickly, it is hyp othesized that neural im cadence rate give decrease because the act of standing takes a good amount of blood that travels down into the legs cause less slash rule book for the ventricle to pump. Once standing for three minutes, it is hypothesized that the arterial contract and musical rhythm rate with both add-on. As it is increasing, it exit also be recognized that the arterial twinge and beat rate impart return to service line.Once data is dispassionate from the variable of posture changes, exercise will be the next variable to look at. Immediately after practice, it is hypothesized that arterial pressure and blood pressure will increase. It is aspect because the dead body is performing high activity, it heart that the heart has to work faster to be able to successfully perform venous return which then increases guessing volume and as a result increases cardiac output. Not exactly will the arterial pressure and pulse rate increase, it will be at its max range. twain minutes after exercise, it is hypothesized that the arterial pressure and pulse rate will decrease. Because the body is starting to calm down and drive back down to resting, the heart doesnt need to produce as high of diagonal volume in that locationfore decrease the cardiac output.Focusing on the perish variable of cognitive stressor, the dependant will have to spell a magnetic inclination of talking to forwards and backwards. It is hypothesized that eyepatch doing this, the defeat arterial pressure and pulse rate will increase. This is to be thought because while the orbit is recite the words the head will be under a lot of stress therefore causing acts of anxiety or nervousness to arise, reservation the heart beat faster than normal. outgrowthFor procedures, refer to Lab 6, Activity 2, in the Anatomy and Physiology Lab Manual.Discussion/ findingTo start off the experiment, a baseline was necessitate in order to be able to compare the different variables thro ugh out the experiment. The equal to(p) was instructed to sit and relax quietly while the blood pressure cuff and pulse plethysmograph were placed properly. After the blood pressure was taken and analyzed, it was implant that the suits blood pressure was 122/64 mm Hg and a pulse rate of 60 bpm. in a flash that the baseline was obtained, continuing with the changing variables could take place. Starting with the variable of postural changes, the field of operation outset recumbd for three minutes. After the both minutes, the subjects blood pressure and pulse rate was taken and gave a rendering of long hundred/52 mm Hg and 60 bpm.Looking back at the system, it was hypothesized that after reclining for three minutes the arterial pressure and pulse rate will both decrease. Cross referencing the given data with the system, it was ready that the results didnt fully match with the guessing. The blood pressure did, in fact, decrease collectible to the relaxation state that the s ubject was in. On the other hand, the pulse rate stayed the same. Reflecting on that and looking at the variables in the environment, it could be said that the subject wasnt in a state of full relaxation. The subject was instructed to recline on a frosty lab table with other subjects and groups in the room. It is possible that the discrepancy in this experiment was the environment in which the subject was instructed to recline and relax.After reclining, the subject was instructed to stand up quickly. Right when the subject stood up, blood pressure and pulse rate were recorded. It was collected that the subjects blood pressure was 132/58 mm Hg and pulse rate of 62 bpm. Relating back to the hypothesis, it was said that the arterial pressure and the pulse rate would decrease. The results obtained and the hypothesis did not match.Further dissecting why the data didnt match the hypothesis, it was discovered that because the subject stood up very quickly, 500 mL or more travels down into the legs. It was thought, payable to that reason it would mean less stroke volume for the ventricle to pump. Looking at it from a different angle, because the amount of blood that travels to the legs, it actually causes the heart to work more rapidly to evenly transport repair amounts of blood through out the body causing the arterial pressure and the pulse rate to increase.Once the subject was standing for three minutes, the reading of the blood pressure was 130/52 mmHg and the pulse rate was 64 bpm. Comparing to the hypothesis, it was said that the arterial pressure and pulse rate would increase trying to bring the body back to baseline. Looking at the results, the blood pressure, in fact, decreased and the pulse rate increase, reservation the results partially confirm the hypothesis. Because it didnt all in all confirm the hypothesis, it could be said that the subjects body wasnt able to get the body completely back to baseline in three minutes. It may have taken a few more mi nutes in order for the body to get back to a rhythmical state.After those variables were explored, the next variable tested was exercise. rather of there being only one subject, two subjects were used. Subject 1 was a healthy contoured subject, someone who plant spirit out on a regular basis and already has endurance. Subject 2 was someone who was scant(p)ly conditioned, who never does toilsome activity. Before all physical activity, a baseline was required so there was data that can be compared. The well conditioned subjects baseline was an arterial pressure of 118/70 mmHg and pulse rate of 61 bpm.The poorly condition subjects baseline read as arterial pressure 122/44 mmHg and pulse rate of 60 bpm. both(prenominal) subjects were instructed to exercise for quintuple minutes, which consisted of running up and down the stairs. Immediately after exercising, the reading of the arterial pressure and pulse rate were taken. The well conditioned subjects arterial pressure read 16 2/62 mmHg and pulse rate of 76 bpm. The poor conditioned subjects arterial pressure read 139/60 mmHg and pulse rate 80 bpm. The hypothesis was sustain that immediately after exercising, the arterial pressure and pulse rate would increase. Not only would it increase, but it would be at a max range. The venous return increased due to the increase in penniless muscle activity. Increasing venous return, increases stroke volume, which then increases cardiac output.One minute after exercising, the subjects arterial pressure and pulse rate were recorded. Subject 1s arterial pressure was 138/70 mmHg and pulse rate was 74 bpm. Subject 2s arterial pressure was 134/65 mmHg and 76 bpm. The hypothesis was affirm that the arterial pressure and pulse rate would decrease but still higher than baseline. As you see reflected in the Results section above, two and three minutes after exercising the blood pressure and pulse rate decreased, further confirming the hypothesis.The third and lowest varia ble tested was cognitive stressor. The subject was instructed to read 12 spelling words forwards and backwards at five second intervals. Before, just like any experiment a baseline needed to be obtained. After the reading was recorded, the first test began. The subject had to spell a series of words, as this was happening, the subject was dependent up to iWorx which is a system that reads blood pressure and pulse rate. Once the test had ended, the data was analyzed and it was found that the hypothesis of the pulse pressure and blood pressure increasing did not apply to the first part of the test.The subjects blood pressure had decreased while the pulse pressure increased. The discrepancy was thought to be that the subject was very comfortable in spelling words therefore the blood pressure decreased but the pressure from spelling in front of other people may have caused the pulse rate to increase. The subject then spelled a series of words backwards, this further confirmed the hypot hesis that the blood pressure and pulse pressure would increase. The focus on spelling the words backwards correctly and the pressure of people watching the subject caused the increase in blood pressure and pulse pressure.Throughout this experiment, it was interesting to see how to different variables in every day life can strength ones blood pressure and pulse rate.For the most part, each hypothesis was confirmed. The hypotheses that werent confirmed, it was an obvious discrepancy that explained why the experiment didnt work out as planned. What can be taken from this experiment is that one can allege a certain level of arterial pressure and pulse rate by the activity that is performed. Arterial pressure and pulse rate are very cutting and can change at any moment. It is good to be knowledgable on what factors effect blood pressure and pulse rate also on how it effects your body.ReferencesBlood Pressure UK(n.d).
