Vital Signs Experiment Essay

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.

This experiment was carried out as noted about in Procedure 1. The resting heart rate was established and used as a baseline value from which to compare all future deviations. While data could

At the latter end of the p-q interval, atrial contraction occurs forcing additional blood into the ventricles. At the beginning of the QRS interval on an ECG reading, the mitral valve closes and the ventricles are at EDV (135ml). During the QRS interval, ventricular contraction occurs increasing the pressure in the ventricle and the aorta. When the pressure continues in the ventricle exceeds the pressure in the arteries, the aortic valve opens and blood is ejected. The increased pressure continues through the t peak. The ventricles are now in ESV (65ml) and the aortic valve is closed. Now the ventricles are relaxed causing pressure to fall and the cardiac cycle starts over again. This ECG reading was from a normal tracing. Keep in mind that an ECV is easy to obtain, but there are some subtleties that are very complex.

The pulse rate increases each time due to the acknowledgment of the pulse and I therefore was able to get more accurate results.

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

The leveling bulb must be leveled with the amount of water in the buret at all times. Timing should begin after 2 ml of oxygen has been produced and must be recorded at 2 ml intervals until 14 ml of oxygen has accumulated. After recording the time, the first part of the experiment is now complete.

The pulse is an indication of an individual’s heart rate. When checking for a pulse in the primary survey, begin with palpating the patient’s radial or carotid artery (Basic Patient Care 2012, p. 50). This may reveal a normal (60-100 beats/min), tachycardia (<100 beats/min), bradycardia (> 60 beats/min) or asystole heart rate. Additionally, the capillary refill may also provide details about a patient’s cardiovascular status. This is performed by applying pressure to the nail bed and calculating the time it to takes to refill to a normal color, which should take no more then a few seconds otherwise suggesting capillary closure (Mick J Sanders, 2012, p. 1400). An additional accessory to Circulation is Hemorrhages, these involve more through examinations of the pulse, blood pressure and warmth of peripheries of patients. Additionally, you must thoroughly look for indication of bleeding, specifically in the areas around the chest, abdomen and externally seen by the eye.

1.No estimation is needed to obtain this value, as it almost immediately follows once the systolic pressure has been identified. 2. To obtain this measure, the article by Alison Cork explains how the physician must listen to the value at which the tapping sound can no longer be heard. This is the diastolic blood pressure measure.

To pressure check for a rebreathing circuit, first attach the breathing system (Y-tube and reservoir bag) and then turn on the oxygen source. Then close the pop-off valve and occlude the Y piece with thumb. Next, generate pressure in the system by pressing the oxygen flush valve until the manometer reads 30 cmH2O. The pressure should not drop below 5 cmH2O in 30

The auscultatory method involves the use of a sphygmomanometer and a stethoscope to listen to Korotkoff sounds and determine the systolic and diastolic arterial pressure (Kapse & Patil, 2013). The mercury and aneroid sphygmomanometers are two types of devices that use auscultatory methods to measure blood pressure (Buchanan, 2009).

a. Deflate the BP cuff at a rate of 5 to 10 mm Hg per second.

1. Maintain a constant water level (head) difference between the two sides of the tank as shown in the diagram by allowing water to overflow through the overflow and outflow tubes. Measure the water level (head) difference.

The effects of exercise on blood pressure, heart rate, respiration rate and electrical activity of the heart were assessed. The measurements of respiration rate, pulse rate and blood pressures were noted as described in Harris-Haller (2016). Data was first taken from subjects in a relaxed position and then followed by sets of reading after exercising based on one minute intervals. The data also noted sitting ECG traces from Harris-Haller (2016). The respiratory rate, pulse, blood pressure, P wave, QRS complex and T wave were defined for each subject. The class average was calculated for males and females and graphed to illustrate the results by gender for each cardiopulmonary factor.

In order to gather the most accurate resting blood pressure the subjects were seated and relaxed for five minutes before taking the first measurement. The blood pressure cuff was placed just above the elbow crease on the left arm. The cuff was fastened and the subject was told to sit comfortably. The cuff was inflated and a beep sounded from the machine signaling the deflation of the cuff and the completion of the measurement. The pulse was then taken by the subject placing two fingers over their pressure point on the inside of their wrist and counting how many times their pulse was felt.

The literature on the effects of exercise of cardiac output maintains the idea that exercise should affect cardiac output- pulse rate, systolic blood pressure, diastolic blood pressure, QRS-pulse lag, P-T and T-P intervals, because of increased heart rate. For our experiment, we tested this theory by measuring our cardiac output before and after some rigorous exercise. We measured the individual cardiac output and then combined the data to compose a class-wide data average. We compared the results of the experiment to what we expected, which was that exercise does affect our heart. Our data from this experiment supported the notion that exercise does, in fact, change cardiac output.
