Carotid Artery Essay

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

View the right internal jugular vein when measuring jugular venous pressure. With aging, the aorta stiffens, dilates, & elongates, resulting in decreased pulsations on the left side. In addition, use caution when palpating & auscultating the carotid artery. Pressure in the carotid sinus may cause a reflex slowing of the heart rate.

All tests were conducted in the same posture; leaning over the lab table with elbows resting on the table and the head down. Students worked in groups of three to four, and each one took turn being the experimental subject, taking the pulse and handling the stopwatch. To measure the radial pulse manually, the subject’s palm was facing upward. The index and middle fingers were used to locate the pulse between the radial bone, which is on the same side as the thumb, and with a slight pressure, the pulse could be found.

An untrained 22-year-old male human subject was chosen. A PT-104 pulse plethysmograph was wrapped around his dominant (right) index finger. Connected through a IXTA data acquisition unit, heart rate was monitored on LabScribe. The recordings were measured with ten seconds of leeway at the beginning and end to allow baseline pulse recovery. Digital marks labeled the time interval of the described action. First the subject’s heart rate was measured during a resting phase for twenty seconds. He was encouraged to relax and remain inactive in order to confirm an accurate baseline reading. For the apneic condition, the subject repeated this

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

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

Cerebrovascular accidents, or strokes, will lead to brain damage that affects the functioning of executive function, memory, language, visuospatial performance and emotional states. Corresponding vertebral arteries and carotid arteries provide blood to the brain from the heart that the carotid arteries are internal and external sections of the thyroid cartilage. Where the optic nerve rests the internal artery distributes into the anterior and middle cerebral arteries. The vertebral arteries arise through the spinal vertebrae and meet the lower pons to form the basilar artery. The brain receives 15% to 20% of the oxygenated blood from the heart and can only endure fleeting interruptions of blood flow before neural operations

Assessing an arterial line the nurse looks at the insertion site does it look red, swollen, is the transducer even with the patient’s right atrium and does the BP readings look accurate? To monitor for accurate circulation, you look at circulation below the site, is there a pulse and are the extremities looking blue? A benefit of this is having a constant BP reading and tells the patients temperature. Some negatives is that it can be an extra risk for infection. Potential complications is the lower part of the extremity is not receiving adequate

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.

Follow a systematic palpate the sternoclavicular, aortic, pulmonic, tricuspid and epigastric areas using a systematic sequence. Using the ball of hand find the apical pulse then tips of finger over the precordium. Note abnormal finding such as heaves, thrills and fine vibration (purring cat). Palpate the other arterial pulses by pressing with the pads of your index and middle finger. Start at the temporal artery and work down to the dorsalis pedis pulse. Abnormal finding such week pulse could be due to cold weather or can indicate sever heart failure or peripheral vascular disease. Strong or bounding pulsations usually occur in a patient with a condition that causes increased cardiac output, such as hypertension, hypoxia, anemia, exercise, or anxiety. A thrill usually suggests a valvular dysfunction.

In the first part of the practical, we will dissect the heart of a sheep and observe its anatomical structure. We will also examine the structure of blood vessels at a microscopic level. My hypothesis is that by examining the anatomy of the cardiovascular system, we will be able to detect differences in both vessels and the chambers of the heart. In the second part of the practical we will examine the electrical activity of the heart. In doing so my aim will be to produce a familiar ECG reading containing a P wave, QRS complex and T wave. Futhermore, we will take blood pressure readings by listening to the korotkoff sounds of the heart using a sphygmomanometer and stethoscope. We hypothesis that the higher the arm position is from the ground, the smaller the blood pressure reading will

Measurement of carotid femoral pulse-wave velocity (PWV), as a reproducible non-invasive index of large artery elasticity and stiffness, enables assessment of the speed of the pulse wave, which is related to the stiffness of the aorta. Aortic PWV has been demonstrated to be a predictor of cardiovascular events and mortality. It is now recognized as an interesting tool for global cardiovascular risk assessment.

A stroke caused by a blocked artery by a blood clot or bursting of a blood vessel because of uncontrolled high blood pressure. There are main three types of the stroke. An ischemic stroke occurs when a blood clot blocks one of the arteries which supply blood to brain. A clot may be caused by fatty deposits (plaque) that build up in arteries and cause reduced blood flow (atherosclerosis) or other artery conditions. (mayo clinic). About 89%, strokes are ischemic strokes. Ischemic stroke includes thrombotic stroke. A thrombotic stroke occurs when a thrombus stuck in one of the arteries that supply blood to the brain. A clot build-up of fatty deposits in arteries. Another type of stroke is called the hemorrhagic stroke. This stroke occurs when a blood vessel leaks or ruptures in the brain. A bold vessel leaks or ruptures from many conditions like uncontrolled high blood pressure or overtreatment with anticoagulants and the weak spot in blood vessel walls. (mayo). Some people experience a mini-stroke it is known as a transient ischemic attack (TIA). A temporary decrease or clot stuck in a vessel in our brain causes TIA. It happens less than five minutes. This stroke does not have any symptom, because the blockage is
