Connecting Body Systems-Cardiovascular System The main function of the cardiovascular system is to provide a network of vessels though which blood is pumped by the heart to all body cells. Specific functional relationships between the cardio- vascular system and other body systems are discussed below.

Medical Word Elements This section introduces combining forms, suffixes, and prefixes related to the cardiovascular system. Most emboli are blood clots (thrombi) that have been transported from a distant vessel by the blood. Other common causes include smoking, diabetes, high blood pressure, obesity, and familial tendency. Pathology Arteriosclerosis Many cardiac disorders, especially coronary artery Arteriosclerosis is a hardening of arterial walls disease, and valvular disorders are associated with that causes them to become thickened and brit- a genetic predisposition. This hardening results from a build-up of a ry as well as a physical examination is essential in plaquelike substance composed of cholesterol, the diagnosis of cardiovascular disease. Over time, some of the most serious cardiovascular diseases it builds up on the inside lining (tunica intima) have few signs and symptoms, when they occur of the arterial walls. Eventually, the plaque hard- they may include chest pain (angina), palpita- ens (atherosclerosis), causing the vessel to lose tions, breathing difficulties (dyspnea), cardiac elasticity.

Emboli in venous cir- are usually required to confirm or rule out a sus- culation may cause death. Sometimes cardiovascular disorders, the medical services of a plaque weakens the vessel wall to such an extent specialist may be warranted.

The physician who treats Arteriosclerosis usually affects large- or medium- these disorders is called a cardiologist. One of the monly use endarterectomy to treat carotid artery major risk factors for developing arteriosclerosis is disease, peripheral arterial disease, and diseases of an elevated cholesterol level (hypercholesterolemia). Other major risk factors include age, family history, smoking, hypertension, and diabetes. Coronary Artery Disease Treatment for arthrosclerosis varies depending on the location and symptoms.

Sometimes, the physician will place a hol- low, thin mesh tube (stent) on the balloon and position it against the artery wall. It remains in place after the balloon catheter is removed and keeps the artery opened. One end of the graft ves- sel is sutured to the aorta and the other end is sutured to the coronary artery below the blocked area. It may be noninfective in nature, caused by thrombi formation, or infective, caused by various microorganisms.

Bacteria traveling in the vein, causing swelling in surrounding tissues the bloodstream (bacteremia) may lodge in the (edema). Varicose veins may develop in almost any weakened heart tissue and form small masses called part of the body, including the esophagus (varices) vegetations composed of fibrin and platelets. Vegetations may dis- reticular veins, which appear as small blue veins lodge (embolize) and travel to the brain, lungs, kid- seen through the skin, and “spider” veins (teleang- neys, or spleen. Scaring of the valves may cause iectases), which look like short, fine lines, starburst them to narrow (stenosis) or not close properly clusters, or weblike mazes.

It should be emphasized that these categories of shock are not absolute rumalaya forte 30pills mastercard, and sig- nificant overlap may be observed order 30pills rumalaya forte overnight delivery. Traumatic shock buy 30 pills rumalaya forte mastercard, for example, may include components of each of the other primary categories. Septic shock often demonstrates hypovolemia, myocardial depression, and distributive abnormalities. This chapter discusses the various types of shock: definitions, the diagnostic workups, and management. Class I hemorrhage represents a loss of 10% to 15% of the blood volume and results in a minimal change in the patient’s vital signs. Recognition of the early stages of shock and appropriate early intervention are the keys to management. Other important etiologies of hypovolemic shock are losses via the gastrointestinal or urinary tracts and extravascular fluid sequestra- tion or “third space” fluid loss. Ongoing fluid losses through these routes may not be diagnosed as readily as is hemorrhage, and, there- fore they require a higher index of suspicion. Subsequent burn wound infections in such a patient could result in septic shock, adding to the complexity of management in these patients. Further- more, a component of inhalation injury likely would add to further resuscitative fluid requirements. Processes such as peritonitis com- monly lead to large-volume retroperitoneal or intraabdominal fluid sequestration. Shock 121 dicitis with abscess formation leads to intraabdominal fluid sequestra- tion, and, despite aggressive fluid resuscitation, shock persists. Septic shock, a form of severe sepsis, is evident when an infectious source is confirmed or suspected, coupled with hypoperfusion despite adequate volume resuscitation. The treatment of septic shock involves adequate fluid resuscitation, point source control of the infectious source (such as drainage of appendicial abscess in Case 2), and other supportive measures, such as nutritional support, ventilation, and renal replacement. Shock following traumatic injury frequently combines aspects of several shock categories. Hypovolemia due to hemorrhage combined with tissue injury and/or bone fractures evokes a potentially more destructive proinflammatory response than hypovolemia alone. Cardiogenic shock may accompany traumatic cardiac injury, tension pneumothorax, peri- cardial tamponade, or myocardial contusion. There are multiple contributors to the systemic inflammatory reaction stimulated by tissue injury. Devitalized tissue, bacterial contamination, ischemia- reperfusion injury, and hemorrhage act together to place the trau- matized patient at risk for hypermetabolism, multiorgan dysfunction, and death. Therefore, the treatment of traumatic shock is aimed at quickly diagnosing the areas of injury, controlling hem- orrhage, restoring circulating intravascular volume, preventing hypoxia, and limiting the extent of secondary damage introduced by inflammation and infection. Exclusion of intraabdominal sources of hemorrhage must be done expeditiously because such injuries require immediate surgi- cal treatment in the operating room. Further sources of hemorrhage include aortic injury with hemorrhage into the chest cavity. Perez nonhemorrhagic source in this patient could be a myocardial contusion with subsequent impairment of cardiac output resulting in cardiogenic shock. This may be diagnosed by echocardiography and treated with supportive measures such as inotropes. Treatment of hypovolemic shock, regardless of the etiology, involves restoration of circulating blood volume and control of ongoing volume loss. In patients with clear evidence of shock, aggres- sive fluid resuscitation is of great importance. For hemorrhagic shock especially, caregivers should follow a systematic approach to resusci- tation, including the airway, breathing, circulation, and disability assessment as outlined in the Advanced Trauma Life Support course. This approach may be both diagnostic and therapeutic and increases the likelihood of recognizing sources of hemorrhage. Fluid resuscitation should be initiated with two large-bore (16 gauge or larger) catheters in the antecubital fossae and connected to the widest administration tubing available to allow for rapid volume infu- sion. Patient assessment for placement of intravenous catheters should take into consideration the location of fractures, open wounds, burns, and areas of potential vascular disruption. The choice of fluid for resuscitation begins with the most efficacious and cost effective. Rapid infusion (less than 15 minutes) of 2L of isotonic saline or a balanced salt solution should restore adequate intravascular volume. If blood pressure and heart rate do not improve following this intervention, suspect hemorrhage in excess of 1500cc or ongoing blood loss. Blood transfusion should follow, using O-positive or O-negative blood in the most critical circumstance or type-specific or fully crossmatched blood if time allows. As a general caveat, no time should be wasted with crossmatching if the patient has a clear source of continuing hemorrhage and remains severely unstable despite crystalloid administration. As a conventional approach to fluid resuscitation, crystalloid and blood product infusions are standard for patients with hemorrhagic or hypovolemic shock. There are alternate solutions, however, that include hypertonic saline, several colloid formulations, and blood sub- stitutes (Fig. The hypertonic component draws water out of the intracellular space into the extracellular space in a type of “autotransfusion. Some formulations add 6% dextran to hypertonic saline in order to increase intravascular oncotic pressure. The beneficial effects of hyper- tonic saline in improving survival have not been clearly apparent in human clinical trials, with the exception of the subset of patients in shock with traumatic brain injury. Total fluid requirements in patients with hypovolemic shock receiv- ing either a synthetic colloid (hetastarch), 5% albumin, or 0.

Quotations are listed under author, with an index of keywords that permits the reader to access a number of quotes with the same keyword. Wherever possible, biographical information about the author and whence the quote originated are included, although it is acknowledged that there are several omissions in this regard. When the original source is not clear, the secondary source has been substituted if it was thought useful for further study for the reader. If the quotation was deened to merit a place in the Dictionary even without full reference being available, it was included. Indeed, it is not necessary for an author to be particularly well known to be in the dictionary if he or she had given birth to a bon mot or a succinct phrase. The majority of the quotations come from the English-speaking medical worlds of Great Britain, Ireland, and North America but several quotes from other rich medical cultures have been included in translation. Whether readers are looking for a suitable quotation on surgery, science, kidneys, or kindness, they should find much here to satisfy. Medicine is both the narrowest and broad- est of subjects, and I have included examples of both the specific and the general. If I have failed to find that favourite concise quote, please send it fully referenced and it will be included in the next edition. Any corrections of birth dates and deaths will be most wel- come and acknowledged in subsequent editions. This page intentionally left blank Contents Quotations  Bibliography  Index  How to Use the Dictionary The sequence of entries is by alphabetical order of author, usually by surname but with occasional exceptions such as imperial or royal titles, authors known by a pseudonym (‘Zeta’) or a nickname (Caligula). In general authors’ names are given in the form by which they are best known, so we have Mark Twain (not Samuel L. Collections such as Anonymous, the Bible, the Book of Common Prayer, and so forth, are included in the alphabetical sequence. Within each author entry, quotations are arranged by alphabetical order of the titles of the works from which they are taken: books, plays, poems. These titles are given in italic type; titles of pieces which comprise part of a published volume or collection (e. For example, Sweeney Agonistes, but ‘Fragmert of an Agon’; often the two forms will be found together. All numbers in source references are given in arabic numerals, with the exception of lower-case roman numerals denoting quotations from prefatory matter, whose page num- bering is separate from that of the main text. The numbering itself relates to the beginning of the quotation, whether or not it runs on to another stanza or page in the original. Where possible, chapter numbers have been offered for prose works, since pagination varies from one edition to another. In very long prose works with minimal subdivisions, attempts have been made to provide page references to specified editions. Unless otherwise stated, the dates thus offered are intended as chronological guides only and do not necessarily indicate the date of the text cited; where the latter is of significance, this has been stated. Where neither date of publication nor of composition is known, an approximate date (e. Where there is a large discrepancy between date of composition (or performance) and of publication, in most cases the former only has been given (e. Spellings have been Anglicized and modernized except in those cases, such as ballads, where this would have been inappropriate; capitalization has been retained only for per- sonifications; with rare exceptions, verse has been aligned with the left hand margin. The Index Both the keywords and the entries following each keyword, including those in foreign lan- guages, are in strict alphabetical order. Singular and plural nouns (with their possessive forms) are grouped separately: for ‘you choose your disease’ see ‘disease’; for ‘coughs and sneezes spread diseases’ see ‘diseases’.

Relaxing at the beach Let this scene transport you to a quiet beach where your cares can melt away rumalaya forte 30pills with visa. Reaching the ocean shore and feeling the cool discount 30 pills rumalaya forte amex, refreshing water lap over your feet rumalaya forte 30pills without prescription, you smell the crisp, salty air and take a deep breath; calmness comes over you. A wave crashes onto the rocks and sends a fine mist high into the air; small droplets spray on your face and feel delightfully refreshing. Seagulls glide effortlessly high above and then dive, skimming the sur- face of the water. Magically, a frosted glass of your favorite beverage appears on a small side table. Sipping and feeling the cold liquid fill your mouth and slide down your throat, you feel refreshed and satisfied, serene and content. You take a look out at the horizon and see a couple of sailboats float- ing lazily in the distance. You feel the warm sun bathe your skin; at the same time, a gentle breeze cools your skin to a perfect balance. A forest fantasy Sometimes a walk in the woods, even an imaginary one, can do wonders for your body, mind, and spirit. Sunlight filters through the branches of the trees, making shadows dance across the ground. You reach a stream with clear water flowing swiftly over and around the small rocks in its bed. Others use these images to help them relax before a stressful event, such as taking a test. We have a few helpful hints for designing your own guided imagery for relaxation: ✓ The most important hint is to enjoy yourself.

Chapter 13 Mindful Acceptance In This Chapter ▶ Accepting the struggle of life ▶ Giving up ego to make life easier ▶ Focusing on the present ▶ Practicing mindfulness ▶ Cultivating your spirituality as your car ever been stuck on a muddy road? Anxiety can be like that: The harder you try to break free, the tighter it seems to grip. In this chapter, we explain how to use acceptance as one way to get out of your anxiety trap. We show how acceptance helps you stop spinning your wheels so you can calmly consider productive alternatives. We discuss how too much con- cern with ego and self-esteem can make seeing the way out difficult, and we explain how living in the present provides a roadway to a more balanced life. Finally, we give you some thoughts about the possible role of spirituality in finding serenity. When you find yourself stuck in the rut of anxiety, don’t slam down on the accelerator. Sit back, let the wheels settle a bit, rock back into the rut, and then gently push forward. Eventually, you’ll discover a rhythm of going for- ward, then rocking back, and your efforts will lead you to solid ground. So why is it that after showing you how to get rid of your anxiety, we tell you to mindfully accept it? But the paradox of anxiety is that the more you feel you must rid yourself of it, the more anx- ious you feel. Imagine going to a carnival or birthday party where someone gives you a Chinese handcuff — a little, decorative, woven straw tube. The harder you pull, the tighter the hand- cuffs squeeze; a way out doesn’t seem to exist. Taking a calm, dispassionate view Anthropologists study the behavior and culture of human beings. They make their observations objectively from a dispassionate, scientific perspective. Study your anxiety and prepare a report that conveys what anxiety feels like in your body, how it affects your thoughts, and what it does to your actions. Then, being as objective as possible, answer the following ques- tions in your report: ✓ Where in my body do I feel tension? Mel’s story that follows provides a good example of how your powers of observation may help you get a handle on your anxious feelings. Mel, a 38-year-old hospital administrator, experienced his first panic attack three years ago. Since then, his attacks have increased in fre- quency and intensity, and he’s even started to miss work on days when he feared having to lead staff meetings. The therapist notices that Mel’s perfectionism drives him to demand instant improve- ment. The therapist, realizing that Mel needs to slow down and back up, gives him an assignment to pretend that he’s an anthropologist on a mis- sion and to write a report about his anxiety. Mel completes the assign- ment as follows: I started noticing a little shortness of breath. I could almost hear the anxiety tell- ing me that I would feel much better if I stayed home because if I went to work, I’d have to talk to a room full of upset surgeons.
