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.

Resting heart contractions were recorded for thirty seconds until the heart rate was less than 60 beats per minute. A stimulator electrode to be used was set to the following states: Amplitude of 4.00 Volts, a stimulus delay of 50ms, stimulus duration of 10ms, a frequency of 1.0Hz, and a pulse number of 30. The electrode was then placed in direct contact with the heart for 30 seconds at which time the data was observed and recorded.

The resting heart rate fluctuates over time because it is under control of the autonomic nervous system and the fluctuations are a result of the sympathetic and parasympathetic systems trying to balance each other out.

of 116 bpm, respiratory rate of 18 breaths/min, and blood pressure of 86/54 mm Hg. The

Breathing rate is measured by one rise and fall of the chest. The best results are after takings someone’s pulse, and when the person being measured isn’t subconscious of it. The professionals usually pretend to carry on taking the heart rate of the client so they don’t realise what’s happening, as the person could start consciously breath and control their breaths.

The pulse can be taken on two pressure points. One on the neck this is called carotid artery however it is sometimes quiet hard to find, so people measure from the wrist, the Radial artery, with two fingers as the thumb as a pulse but is uneven and can affect accuracy. The average heart rate for 15-20 year olds is 122-163 bmp. Exercise causes the blood to pump faster, making our intake for oxygen more and temperature rise, which creates sweat.

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

He measured their resting pulses. Their pulses were 45, 45, 64, 50, 58, 49, 47, 55, 50, 52 beats per minute. The average resting pulse of athletes in the general population is normally distributed with a pulse rate of 60 beats per minute.

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.

-Heart rate is the number of times a person 's heart beats per minute. When you are preforming a type of exercise that will increase your heart rate, then your heart will pump blood all around your body faster and especially to muscles that are working the most because they require the most oxygen because of the intensity they are working at. It is vital to take your resting heart rate and the normal heart rate is 60-100bpm. For example, our cardiovascular exercise was cycling on a stationary bike for 20 minutes at a reasonable pace and this will depend on whether your heart rate will increase at a slow, fast or steady rate. However, the first 5 minutes we cycled at a very fast pace in order for your heart to pump more blood all around the body and to the required muscles in order for them to work harder. But the response is that the heart rate levels off, which means that it becomes steady so that after beginning the exercise and you’re like 5 minutes into it then your heart rate will stay the same or increase by little bits unless you change the intensity all the time which is not required when doing cardiovascular exercises.

A normal heart rate at rest can range from 60-100 beats per minute (BPM) for adults. Most of the time a

· Instructions for obtaining your own heart rate: to locate your pulse on the side of the neck, place your first two fingers, which are called the index and middle finger on the side of the neck in the hollow between the windpipe and the large muscle in the neck.
