Cuff Lab Report

The Korotkoff sound is constantly monitored as the cuff continues to be deflated slowly until the pulse sounds have disappeared. Then the fifth Korotkoff sound was recorded as the diastolic BP after another 10 to 20 mmHg the cuff may be completely deflated to avoid limb compression. After the procedure is complete the patient should be informed and left comfortable; the results must be explained and documented.

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

Activity 1: Investigating the Refractory Period of Cardiac Muscle Results: Briefly describe what happened when you applied the electrical stimuli to the heart. (1 mark) RESULTS: Applying single shocks in succession or multiple stimuli to deliver shocks at 20 stimuli/sec led to the formation of successive double peaks with a period of pause between them. This doublet is the normal systole closely followed by the extrasystole resulting from external stimulation, and then compensatory pause so the heart may resume normal beating afterwards if there is no further stimulus. Question 1: The refractory period of cardiac muscle cells is significantly longer than the refractory period of skeletal muscle cells.

Using the cuff bulb, the cuff was inflated until no sounds were heard through the stethoscope. Once this point was reached the cuff was slowly deflated and listening for the systolic and diastolic readings began. The systolic reading is the first rhythmic sound heard and the diastolic is the last rhythmic sound heard. The blood pressure reading was recorded on paper. The subject was then instructed to climb the stairs at a constant rate.

Blood flow is constricted here and no sound can be heard. As the pressure in the cuff is slowly alleviated, blood begins to flow through the vessel and a sound can be heard. This is systolic pressure. In exercise 2 when a sound could no longer be heard, this was diastolic pressure and is the point where continuous flow has been restored (VanPutte et al., 2014).

Diastolic pressure represents the point of greatest relaxation of the artery wall and is the last regular beat heard.

By occluding the artery in the arm, the blood passing through has an audible turbulent flow as opposed to the inaudible normal laminar flow. The turbulent flow creates what is known as Korotkoff sounds which are indicative of the sound of systolic pressure. As you release the pressure from the cuff, at the first sound, mark the pressure as the

Blood pressure is the produced by the blood flow on the vein walls and BP is one of the 4 major vital signs. Per pulse, blood pressure differs between the maximum ( called systolic ) and the minimum ( called diastolic ) pressures.Due to the pumping of the heart and the resistance of the veins, the blood pressure decreases while the circulating blood was moving away of the heart all the way thru the arteries. It decreases seriously with the smaller arteries and the arterioles, continuing to reduce while the blood was moving across the capillaries back to heart all the way thru the veins.

The primary outcome measure was blood pressure and is measured by the auscultation method using a mercury sphygmomanometer. The secondary outcome in the study was heart rate and was measured

The diastolic arteriole pressure measurement is obtained by measuring the pressure in the arteries when the heart is refilling with blood. At this time the heart is resting and is between beats (American heart association, 2014, para.2).

Blood pressure is a measure of the rate of force that drives blood to the tissues in the body. It is a mean measurement of the pressure in the arteries. (Sherwood, 2012) Increased pressure causes a raised pulse rate. (Silverthrone, 2013) Higher arterial pressure, blood flow and cardiac output due to vasodilation are shown to be induced by exercising. (Sherwood, 2012) The investigation aimed to study if there would be an effect on the pulse rate, due to exercise. The null hypothesis was there would be no significant change to pulse rate before, during and after exercising.

First Adam was asked to sit in a chair, relaxed while we took a set of vital signs. This situation was used as a means of calculating Adam’s resting vital signs. The average resting blood pressure is 120/80 mmHg, however Adam is showing a slightly higher resting blood pressure. Although his blood pressure is above average it is still below the maximum healthy blood pressure which is 140/90 mmHg. Adam had 22 respirations per minute and they were full depth and regular rhythm. His respirations are ever so slightly above the average breaths per minute in a resting state as the average is between 12 to 20 beats per minute. Adam’s heart rate was 70 beats per minute with a regular rhythm and full beat. His heart rates falls between the average resting heart rate of 60 to 80 beats per minute. Adam’s respirations and heart rate should be relevantly relaxed as there is minimal strain on his body, resulting in minimal amount of oxygen needed to supply his muscles, cells and tissues. However the rates should be slightly raised to that of a person who is lying down as the heart has to pump a little harder to ensure the blood and hemoglobin (which carries the oxygen) can reach the upper parts of the body and supply the cells with the needed oxygen and nutrients. Adam’s pupils remained equal and reactive to light, his skin was normal and he had an LOA of x3 as he was well aware of who he was, where he was and the date. Generally in a resting state ones vitals

The blood pressure of an individual is affected before and after reaching the steady state. .There is increase in the systolic and diastolic blood pressure during steady state. These increases in the pressure represent the pressure in arteries. This pressure is while the heart is contracting and

We decided to measure the subject’s pulse and respiratory rates whilst sitting down because there would be no additional stress on their heart, which would increase their heart rate. Their heart rate should also return to its resting heart rate due to the decrease of muscle use.

The results gathered from each exercise achieved each objective. The results of the effects of position and exercise on the heart rate and blood pressure showed that there is a high increase in pulse rate and in blood pressure after the post-exercise. The pulse rate indicated that as your arteries expand each time the ventricles pump blood out of the heart when exercising, exercise increases cardiovascular system attempting to deliver more oxygen to the muscles. When a person is standing, blood tend to be drawn into the extremities thus the heart will need to pump harder and faster this causes an increase in blood pressure and heart rate as shown in Table 1 and 2. The opposite happens when a person is sitting, the blood pressure and heart rate will tend to be lower because blood tends to pool in the abdomen and the effects of gravity become less. There is an exercise-dependent changes in heart rate, the heart rate increases during exercise where as no change in heart rate
