Mean Arterial Blood Pressure

...arterial blood pressure is the average arterial pressure in a cardiac cycle. It is set by cardiac output and total peripheral resistance; it sets the average driving pressure and controls the flow. The pulse pressure is the difference between the highest and lowest pressure (systolic and diastolic blood pressure) readings during a subject’s cardiac cycle. Both mean arterial pressure and pulse pressure are detected by baroreceptors. The baroreceptors respond to stretching of the arterial wall so that if arterial pressure suddenly rises, the walls of these vessels passively expand, which stimulates the firing these receptors (Ottesen et. al., 2011). If arterial blood pressure suddenly falls, decreased stretch of the arterial walls lead to a decrease in receptor firing. Baroreceptors are found in the main arteries, the aortic arches and carotid arteries. The addition of different chemicals into the bloodstream causes changes to occur in the heart rate, mean arterial pressure and pulse pressure. These changes are detected by the baroreceptors. Adrenaline and noradrenaline cause similar responses to the cardiovascular system. They have a sympathetic effect, causing an increase in the mean arterial pressure, pulse pressure and heart rate. Conversely, acetylcholine has a parasympathetic effect, the heart rate and blood pressure drops. The aim of the experiment was to see the changes in the cardiovascular parameters of mean arterial pressure, pulse pressure and heart......

Vessels and Honour

...VESSELS OF HONOUR But in a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some to honour, and some to dishonour. If a man therefore purge himself from these, he shall be a vessel unto honour, sanctified, and meet for the master's use, and prepared unto every good work. I normally use to think this scripture was for some special group of people till I met four lepers at the entrance of the city gate. Rejected by all but chosen by God to fulfil his prophecy these Lepers did not only have faith but also Love. In times when women killed their kids for food, these lepers thought of the nation when they took over a camp by the workings of God. Israel had an army that God could have used but God chose the four lepers instead. In life we mostly consider ourselves unworthy because of rejections we face in the hands of men. We look down on ourselves because something we lack or feel we lack and say we are not good enough. But God thinks otherwise if we are faithful to Him and try our best to please Him. God doesn't make mistakes and does not wish anyone to suffer but to give Love, Peace and Joy to all men. You may think God has abandoned you but God is positioning you to fulfil His prophecy. Whenever you are rejected by those you Love tell yourself, “they might be doing it for evil but God is turning it into good, and that many may be saved". BY APOGEE...

Blood Pressure Regulation

...Blood pressure regulation and changes occurring after increase in blood pressure Each time the heart pumps, it sends blood all over the body to supply organs and tissues with oxygen and nutrients. The strength of the force created as the heart pumps blood into the vessels together with the vessels’ resistance to the blood flow is defined as the body’s blood pressure (Darovic, 2002). A normal range blood pressure (BP) must be between 100-130mmHg systolic (when the heart is beating) and 60-90mmHg diastolic pressure (between heart beats) (Sherwood, 1997). Many factors can change blood pressure, including exercise and diet. The regulation of BP within the body is tightly maintained by nerves, hormones and renal control in relation to three factors: cardiac output, peripheral resistance and blood volume. However, malfunction of the controlling mechanisms can cause abnormalities such as hypertension that could have dangerous outcomes such as stroke or heart failure. The body contains physiological mechanisms that work to precisely control the daily BP of an individual (Guyenet, 2006). Cardiac output (CO) is the amount of blood pumped by the ventricles per minute; it will be determined by the amount of blood ejected from the ventricles each heart beat (stroke volume) and the number of beats per minute (heart rate) (Sherwood, 1997). CO is one of the most important contributors to blood pressure. The capacity of the blood vessels to dilate and constrict will influence their......

Blood Vessels

...Blood Vessels Blood vessels are part of the circulatory system, which passes nutrients, blood, hormones, and other important substances to and from body cells in order to maintain homeostasis. The blood vessels are responsible for transporting blood throughout the body. There are three major types of blood vessels: arteries, veins, and capillaries. Arteries An artery is any of the vessels that, with one exception, carry oxygenated blood and nourishment from the heart to the tissues of the body. The exception, the pulmonary artery, carries oxygen-depleted blood to the lungs for oxygenation and removal of excess carbon dioxide. Arteries are muscular and elastic tubes that must transport blood under a high pressure exerted by the pumping action of the heart. The pulse, which can be felt over an artery lying near the surface of the skin, results from the alternate expansion and contraction of the arterial wall as the beating heart forces blood into the arterial system via the aorta. Veins Veins are similar to arteries but, because they transport blood at a lower pressure, they are not as strong as arteries. Like arteries, veins have three layers: an outer layer of tissue, muscle in the middle, and a smooth inner layer of epithelial cells. However, the layers are thinner, containing less tissue. Veins receive blood from the capillaries after the exchange of oxygen and carbon dioxide has taken place. Therefore, the veins transport waste-rich blood back to the lungs and......

Intracranial Pressure (Icp

...Intracranial Pressure (ICP): Overview: ❑ Intracranial pressure (ICP) is the hydrostatic force measured in the brain cerebrospinal fluid (CSF) compartment. Intracranial Pressure (ICP) is the combination of the pressure exerted by the brain tissue, blood, and cerebral spinal fluid (CSF). The modified Monro- kellie doctrine states that these three components must remain at a relatively constant volume within the closed skull structure. ❑ If the volume of any one of the three components increases within the cranial vault and the volume from another component is displaced, the total intracranial volume, and therefore, pressure, will not change. Factors that influence ICP under normal circumstances are changes in arterial pressure, venous pressure, intraabdominal and intrathoracic pressure, posture, temperatue and blood gases, particularly CO2. ❑ Normal ICP ranges from 0 to 15 mm Hg; a sustained pressure above the upper limit is considered abnormal. ICP can measured in the ventricles, subarachoid space, subdural space, epidural space or brain tissue using a pressure transducer. ❑ The purpose of Intracranial Pressure (ICP) monitoring is to trend the pressure inside the cranial vault. The pressure readings determine the interventions necessary to prevent secondary brain injury, which can lead to permanent brain damage and even death. ❑ If the intracranial pressure is in the range of 20 – 25 mmHg, therapeutic interventions, medical and/or......

Blood Pressure

...Adult baseline observations : Blood pressure The purpose of this assignment is to reflect on a chosen experience that I have identified as requiring more knowledge to complete this skill competently. I have chosen to do my learning contract on adult base line observation – blood pressure. The reason I have chosen this skill is because my first experience of taking a blood pressure was not a positive experience and to this day I still get nervous taking someone’s blood pressure. I can do the skill confidently now but feel I need to understand the theory around it to communicate the findings with the woman. When I was first learning to take someone’s blood pressure in intensives I was put down in front of our group by a tutor. I feel this would not have happened had I had more knowledge around the theory before the class which was of my own fault as I hadn’t read the modules thoroughly. I know the normal ranges of blood pressures for adults and how to get the systolic and diastolic numbers but if I was asked by a woman what these numbers mean, I would not be able to correctly and confidently communicate these with her. Existing knowledge - What do I already know about this topic/Skill. • I have had my own blood pressure taken by my doctor many times. • I have practiced taking blood pressures in akonga and intensives • I have taken women’s blood pressure on placement and during follow throughs appointments • I have passed my practise skill sheet for......

Peer Pressure

...Reviving Peer Pressure Nobles International School English Department Shakib Arsalaan * Abstract Almost everyone has experienced peer pressure before, either positive or negative. Peer pressure is the act of peers to get a teenager to do something they usually wouldn’t do. It is so easy to give in to peer pressure because everyone wants to fit in and be liked. Especially when it seems like “everyone is doing it”. Yet whenever we hear the word Peer Pressure we immediately think towards the negative side of it. We don’t usually think of positive peer pressure. This research is going to understand why that is happening with the help of statistics, interviews, and survives. * * Contents * Reviving Peer Pressure Introduction What Is Peer Pressure Types of Peer Pressure How does it Affect Teenager On what measures does it affect the society?

Air Pressure

...water to meet ship’s requirement. Major Parts and Function Centrifugal Pump: PK130 filter pump, delivers the feed water at a pressure of up to 4 bar through the cartridge filter and from there to the high pressure pump PP160. This centrifugal pump has its own integral electric motor. High-Pressure Pump: PP160 is a positive displacement pump. (plunger pump) this pump delivers feed to the PT modules at a pressure of up to 65 bar. (note: pressure is controlled by VS160). The pump is powered through a belt drive from a three-phase motor. Minimum feed pressure to this pump is 0.5 bars. Pulsation Damper: The pulsation damper fitted on the high-pressure pump discharge converts the pressure fluctuations, common for a plunger pump, into a steady pressure. It consists of a pressure vessel, internally separated by an diaphragm into two sections. The outermost section is filled with nitrogen at a pressure of 30 bar. The pulsation’s from the 3 plungers of the HP pump are absorbed by the gas pressurized membrane. It is normal to observe pulsation’s in the pointer of PI160 when pointer is rising through 25 to 32 bar, (resistance against gas pressure). Sand filter: The sand filter retains all sediment particles over 50 (m in size. As the density of these particles increases, the pressure drop across the inlet and outlet increases. To reduce this pressure drop and remove these particles, the sand filter is backwashed by air and feed water (generally when 2 to 2.5 bars are......

Peer Pressure During Adolescent

...Peer pressure is one of the leading problems of adolescence. Peer pressure can lead to many problems. Peer pressure can be to spoke weed, to drink alcohol, to dress differently, to change yourself physically to make friends, and maybe, to a lesser extent, to not study for a test to go see a movie. All teenagers, and all people go through peer pressure -- it's not just in high school. A co-worker might say to you, "Let's go to the club instead of this meeting," and some people might give into that. However, solely regarding adolescents, it's detrimental, but it really depends on what they're being pressured into doing. If they're pressured into cheating on a test, that can lead to lower grades, and even suspension or expulsion. If they're pressured into smoking, this can lead to addiction, and this can lead to health problems, like asthma, blindness, or throat and lung cancer. If they're pressured into drinking alcohol, this can lead to addiction, alcoholism, recklessness, and even alcohol poisoning, which can lead to death. If they're pressured into changing their physical appearance to make friends, this can lead to some serious issues, such as bulimia and anorexia, which has been linked to excessive weight-loss, hair-loss, discoloration of the skin, dizziness and fainting, lack of energy, chronic sore throats, and broken blood vessels in the eyes, among many other detrimental things. Ultimately, this can lead to death. Peer pressure can cause teenagers to become dependent......

Blood Pressure

...Blood pressure is the measure of the force of blood pushing against blood vessel walls. The heart pumps blood into the arteries, which carry the blood throughout the body. High blood pressure, also called hypertension, is dangerous because it makes the heart work harder to pump blood to the body and contributes to hardening of the arteries, or atherosclerosis and to the development of heart failure. High blood pressure is rarely accompanied by any symptoms, and its identification is usually through screening, or when seeking healthcare for an unrelated problem. A proportion of people with high blood pressure report headaches, particularly at the back of the head in the morning, as well as light-headedness, vertigo and buzzing or hissing in the ears, altered vision or fainting episodes. These symptoms, however, might be related to associated anxiety rather than the high blood pressure itself. The exact causes of high blood pressure are not known, but several factors and conditions may play a role in its development, including: * Smoking * Being overweight or obese * Lack of physical activity * Too much salt in the diet * Too much alcohol consumption (more than 1 to 2 drinks per day) * Stress * Older age * Genetics * Family history of high blood pressure * Chronic kidney disease * Adrenal and thyroid disorders The higher your blood pressure, the higher your risk of serious health problems in the future.

Pressure Ulcer Wound Care

...Pressure Ulcers: Wound Care Assignment Harman Unitek College Foundations of Nursing VNSG 100 Mr. Dhanda November 10, 2015 Pressure Ulcers: Wound Care Assignment Have you ever wondered what it looks and feels like if our skin gets torn up? You haven’t right? There are approximately 2.5 million who get pressure ulcers from hospitalization each year. From those 2.5 million patients, 60 thousand patients die from complications (Cooper & Gosnell, 2015, para. 4). In this essay, I will be explaining the normal causes, common treatment (tx), and prognosis for healing. Pressure Ulcers (PU) overall usually occur when there is sufficient pressure on the skin over bony prominences causing blood vessels in an area to collapse. Pressure ulcers result in ischemia or lack of oxygen and nutrients to the cells. PU usually take place over bony prominences such as: sacrum, scapula, elbows, heels, inner and outer knees, back of the head, and the hips. Since we are talk about stage III pressure ulcers, PU involves full thickness tissue loss where the subcutaneous fat is sometimes visible, but bones, tendons and muscles are not exposed. Stage III pressure ulcers vary depending on the location which also include: bridge of nose, ear, and the occiput. Deep stage 3 PUs develop in areas within layers of deep adipose tissue. The two main factors that play a role in development for pressure ulcers are shearing force & friction. Shearing force involves when the tissue layers of the......
