When the blood pressure of a patient is taken, it is common practice to measure it with the patient sitting in the up-right position with the arm resting on the arm of a chair and feet flat on the floor. The reference point for the measurement of BP is the right atrium, the so-called ‘heart level’ (Guyton, 1986). Though, the guidelines of the World Health Organistation/International Society of Hypertension (WHO/ISH) recommend that the BP be measured with the patient comfortably seated with the arms supported at heart level (1993). It has been proposed that BP should be measured in the sitting, standing, and the supine position (Netea 2003). It is suggested that the BP measurement from the sitting and supine position will produce similar results if the extremity is at the level of the heart. Because the upper extremities are easily accessible by medical professionals, they are utilized more-so than the lower extremities. In order to obtain an approximant heart level in the sitting or standing position, resources suggest that we use the level of the midsternum as a point of reference when taking blood pressure measurements (Netea 2003). For the supine position, resources suggest that the heart level lies approximately half the distance between the surface in which the patient is lying on and the top of the sternum (Netea 2003). Though not common in everyday practices, the BP measurement of lower extremities sometimes may be the only alternative; such as, colonoscopies or
The importance of manual blood pressure readings are often overlooked, even by experienced healthcare providers. Manual blood pressures closely approximate a person’s direct arterial measurements. However, there have been studies that
(Marieb and Hoehn, 2010, p 703) defined Blood Pressure (BP) as ‘the force per unit area exerted on a vessel wall by the contained blood, and is expressed in millimetres of mercury (mm Hg)’. BP is still one of the essential and widely used assessment tools in healthcare settings. Nurses generally record the arterial BP which is the forced exerted blood that flows through the arteries, to establish a baseline and to determine any risk factors. BP
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
When checking for orthostatic changes in vital signs the nurse should measure the serial blood pressure and take the pulse of a patient in the supine, sitting, and standing positions. The nurse should first start by placing the patient in the supine position and allowing the patient to rest for 2 to 3 minutes before taking the blood pressure. Next, the nurse should place the patient in the sitting position with their legs dangling off the side of the bed. Then the nurse should allow the patient to rest for 1 to 2 minutes before measuring the blood pressure once again. Lastly, the nurse should reposition the patient to the standing position and should allow 1 to 2 minutes of rest before proceeding to the last blood pressure measurement. Orthostatic changes in the patients pulse and blood pressure need to be monitored closely because they can indicate signs of dehydration concerning the gastrointestinal system. Usually while the patient is in the standing position the systolic blood pressure will decrease 10 mm Hg, and the diastolic blood pressure will increase a bit. Now, when the systolic blood pressure decreases by 20 mm Hg, the diastolic blood pressure decreases by 10 mm Hg or higher, and there could be no change in heart rate or there could be an increase in the heart rate of 20 beats/minute or higher while reposition from the supine position to the
A sphygmomanometer was used to measure the blood pressure and heart rate of the subject. First, the basal heart rate and blood pressure for each subject was collected by taking the mean of the data on the left arm from three
An A-line blood pressure reading is considered more accurate than the cuff pressure reading. During initial assessment, it is routine to compare the A-line blood pressure with the cuff blood pressure. A-line blood pressure readings are higher than the cuff blood pressure readings, and more than a 10% difference may be due to equipment error. Nonivasive blood pressure reading is the most frequently performed clinical parameter and at the same time , not accurately done procedure. Accuracy of the blood pressure reading is vital to the critical care interventions . Clinical situations such as circulatory shock and use of vasopressors, resulting from poor systemic blood flow reduces the intensity of Korotkoff sound. There fore, when you are evaluating cuff blood pressure, make sure that the placement on the arm, cuff size, and techniques are accurate. The cuff bladder circumference should be more than 80% of the arm circumference, and the height of the bladder should be more than 40% of the limb circumference. If the cuff is too small, the BP reading will be high, and a big cuff will give a lower than accurate reading. Remember that the cuff should be 1 inch above the ante cubital fossa and the hand at the heart level. If you need to repeat the reading, wait until the mercury comes to zero, and then wait 1–2 minutes before reinflating again; otherwise, it may produce a
It was found to be slightly below average. The blood pressure was 72.5/115.5mmHg, on average. A person should aim to have a blood pressure of 80/120mmHg. It can be normal for some people to have a lower pressure. This was measured using a sphygmomanometer wrapped and pumped around the upper arm, and a stethoscope is then placed below the wrap on top of the brachial artery on the inside curve of the elbow. Two fingers were placed above/near the carotid artery and the pulsations per minute were counted. This determines the heart rate. On average, the heart rate found was

Getting your blood pressure taken is the first thing that nurses do when giving a check up to their patients. When getting blood pressure checked the nurses put the arm ring, which goes around the arm of the patient, is very uncomfortable and bulky. I have thought of a way that uses newer technology. The supplies I will be using would be the blood pressure monitor and a piece of the heat monitor. The piece of the heart monitor I would be using is the clamp that goes on the patient’s finger. The reason I am going to use this is because it is, seems to be, the more efficient way to make the blood pressure monitor less uncomfortable and bulky as I had stated earlier. Sense I’m not using the clamp for the heart monitor to check the heart I need to enhance the clamper. The way I would enhance the clamper would be to make the sensor a little more sensitive to the blood flow going through the arteries. Instead of the blood pressure monitor going around the patients arm it would clamp on top the finger. In order to get the proper measurement,
Convenience sampling was used to recruit patients with reported uncontrolled BP from a Veterans Affairs Medical Center clinic located in Brooklyn and Manhattan (July 2006 to March 2009).
The patient should be seated with the feet flat on the floor. The BP is obtained in both arms,
Blood pressures can be obtained by invasive or non-invasive means. When carrying out a skill such as blood pressure, the nurse needs not only to have the capability of reading the results on the electrical sphygmomanometer, they also need to have the understand of what the results mean and be able to decipher if the results are normal for that patient. Even though a range of what is deemed to be normal is given, a patient may have low blood pressure, which is slightly lower than the normal range, however consistency and adhering to and following that patient’s care plan will enable you to see that. Just as if the blood pressure reading is high.
My patient’s blood pressure is between 120/80 and 139/89 mm Hg concluding the diagnosis to be pre-hypertension. The lifestyle choices that I would encourage to keep his blood pressure in control would be to exercise on a regular basis, eat healthier, eat less sodium, and to cut out smoking he if has an persistent everyday continuation. Exercising daily may possibly lead to eating healthier and eating less sodium by reading nutritional labels. An everyday routine of exercising can set the trend for other healthy habits. This is due to the fact that good habits tend to cluster. With these everyday lifestyle changes, my patient can keep his blood pressure under control and lower his risk for developing hypertension.
The pulsatile component of blood pressure has received notable awareness as an important hazard for cardiovascular disease. To anticipate the cardio vascular events central blood pressure measurement plays an important role. If the blood vessel are of high compliance or low stiffness, the pressure exerted on the walls of blood vessel or arteries during the systole is the lowest. But due to wave reflection, the blood pressure in the upper limb does not provide the central blood pressure. Therefore, modern researchers are deeply interested to find a noninvasive method of measuring central blood pressure and the aortic stiffness.
