Encouraging and helping people to not start smoking or to stop smoking is a very important step for the health of your community order 500 mg xeloda amex. But it is also very important to create an environment and policies that help people who want to quit smoking and that discourage people from smoking order xeloda australia, especially in public places order xeloda 500mg amex. Smoking damages the cells lining your blood vessels and heart, and leads to the build up of plaque that hardens and narrows your arteries. National Center for Chronic Disease Prevention and Health Promotion Division for Heart Disease and Stroke Prevention Smoking and secondhand smoke causes Cancer in many organs of the body. Some people have a hard time telling smokers not to smoke around them or around their children. This activity will let you practice what you say when someone smokes around you or your family. The smoke seems to be drifting right over Marlas baby, and it is burning Marlas eyes. National Center for Chronic Disease Prevention and Health Promotion Division for Heart Disease and Stroke Prevention Are You Ready to Stop Smoking?

Five Steps To Quit Smoking Activity 146 Quitting smoking is one of the most important things you will ever do. Cigarette smoke contains more than 7,000 chemicals, and 200 of these are poisonous. If youre not sure exactly which quit methods are right for you, visit the Quit Smoking Methods Explorer to learn more. We all need different things, so be sure you let friends and family know exactly how they can help. Remove Cigarettes and Other Tobacco From Your Home, Car, and Work Stay strong; you can do it! Talk to Your Doctor or Pharmacist About Quit Option add pic of person talking to doctor or pharmacist It is hard to quit smoking on your own, but quitting cold turkey is not your only choice. By providing support to smokers, individual or group counseling they can help you quit smoking. The two main types of smokeless tobacco in the United States are chewing tobacco (loose tobacco leaves) and snuff (fnely ground tobacco). Users put the tobacco in their mouths, chew on it, and spit out the tobacco juices, which is why smokeless tobacco is often called spit or spitting tobacco. Here are some of the dangers Sugar in chew tobacco may cause decay in exposed tooth roots. National Center for Chronic Disease Prevention and Health Promotion Division for Heart Disease and Stroke Prevention Some Alternatives to Chew or Snuff Tobacco Sugarless Gum It can keep your mouth moist and active without the risk of chew tobacco. Healthy Snacks Fruit and vegetable sticks can also be substitutes for chew tobacco. Activity 148 Work together with schools, health professionals, and community members and organizations to support education of children in grades K12. These people and organizations can help young people develop the skills they need to avoid tobacco use. National Center for Chronic Disease Prevention and Health Promotion Division for Heart Disease and Stroke Prevention This page left intentionally blank Children and Teens 15 Objectives By the end of this session, community health workers will be able to Explain why heart disease prevention begins in childhood. Which of the following are related to overweight and obesity in children and teens? Eating large amounts of food that are high in fat, sodium, and sugar and drinking too many sugary drinks. Sitting and playing computer games for a long time each day instead of being physically active. Prevention Begins in Childhood Talking Points In earlier sessions, we have focused on adults, but preventing heart disease should begin in childhood. Its much easier to start healthy lifestyle habits in childhood, and the habits we start early are more likely to stay with us throughout our lives. Another important reason to start heart disease prevention in childhood is that this disease begins in childhood. We need to focus on preventing of heart disease in younger children so that they dont develop it as adults. Talking Points Science shows that high blood cholesterol levels in childhood may lead to developing atherosclerosis later in life. Atherosclerosis is the build-up of plaque on the artery walls, which reduces the blood fow through the arteries and makes the artery walls stiff and less fexible. As we know from earlier sessions, this condition leads to heart disease, heart attack, and stroke. To prevent atherosclerosis from developing, children and teens should Not use tobacco. Health Resources for Parents Talking Points Some parents may not have their children tested for diabetes and high cholesterol because they think they cant afford a doctors visit. But, Medicaid is available in every state to provide heath and dental services for children under age 19 with low family incomes. When they call the free and confdential hotline, they will be connected directly to someone from their state who will help them apply. Depending on the state, they can do the application through the mail, over the phone, or even online. Talking Points There is increasing evidence that the build-up of plaque in the arteries of children and teenagers is linked to high cholesterol levels. Because there are no outward signs of this build-up, most people wont be aware of it until they have a heart attack or stroke as adults. The best way to avoid heart disease later in life is stop it before it begins in children. By eating healthy foods, not smoking, being physically active and keeping a healthy body weight, children and teenagers can delay or prevent heart disease later in life. Write the adult cholesterol numbers on a fipchart so they can see how close normal cholesterol levels are for children, teens, and adults. Blood Pressure Talking Points Childrens blood pressure should be measured starting at age three during a visit to the doctor, a school nurse, or a local clinic. Blood pressure should be measured with a child-sized blood pressure cuff, not an adult-sized cuff.

This can occur if a diabetic patient Risk factors for developing type 2 diabetes include does not take her insulin or pills or does not follow a increasing age, obesity, family history of type 2 dia- diabetic diet. There is a strong high glucose levels lead to loss of glucose in the urine, genetic basis for type 2 diabetes, likely due to multiple which pulls water along with it, leading to excessive genes. If one identical twin is affected, the other has a loss of water from the kidneys. Certain eth- tion, which further concentrates glucose in the blood nic groups are also at higher risk. Weight loss occurs both Americans, Hispanic Americans, American Indians, as a result of water and calorie loss. Most patients In type 1 diabetes, this scenario can occur abruptly develop type 2 diabetes after the age of 40; however, when insulin is severely deficient. A condition called there are increasing numbers of younger type 2 diabetic ketoacidosis develops. When ketoacid levels rise, the blood becomes acidic, which impairs enzymatic reactions Diabetes can cause many problems in pregnancy. This results in abdominal pain, the first trimester, about 510% of fetuses develop major nausea, and vomiting.

Prevention of hypoxia initially outweighs concerns for hypercapnea cheap 500 mg xeloda with mastercard, and regulated oxygen delivery with appropriate oxygen saturation goals can reduce the incidence of hypercapnea buy xeloda 500mg low cost. Venturi masks are the preferred mode of choice when selecting an oxygen supplementation device because the amount of oxygen delivery can be controlled xeloda 500mg amex. An oxygen saturation of 90 to 92% and a PaO2 of 60 to 65 mmHg gives good oxygen saturation and is less likely to lead to hypercapnea. Patients should increase the dose and or frequency of current bronchodilator therapy initially to every four hours. The guidelines, although stating that -2-agonists should be used first, do so because of a larger body of evidence supporting their efficacy. The guidelines go on to state that there is no evidence to show a difference in efficacy between the different classes of short-acting bronchodilators. The use of combination therapy is still controversial because there is little evidence to support its use. The possibility of adding methylxanthine medications, such as intravenous aminophylline or oral theophylline, to patients with severe exacerbations can be considered. The evidence for use of these medications is inconsistent and generally only exhibits modest improvements in lung function, with an increased rate of adverse events. If these medications are going to be used, it is recommended that serum theophylline levels be monitored. Corticosteroid Therapy Corticosteroid therapy is proven to reduce symptoms and improve both gas exchange and airflow in randomized control trials. The optimal dose and duration of corticosteroid therapy is still unknown and the length of steroid taper is left to the judgement of the clinician. There is evidence that 10 to 14 days of therapy beginning with 30 to 40 mg of pred- nisolone daily is an appropriate compromise between efficacy and safety, however, the strength of the recommendation is weak and based only on expert consensus opinion. Antibiotic therapy is shown to be most useful in patients with severe exacerbations. Patients with increased volume or purulence of sputum as well as with dyspnea are more likely to benefit from antibiotics than those without these three symptoms. Meta-analysis, however, supports the use of antibiotic therapy in patients with purulent sputum plus either increased volume of sputum or dyspnea. Patients with severe exacerbations requiring mechanical ventilation have also been shown to benefit from the use of antibiotic therapy. Studies have shown a correlation between the type of bacterial infection and the underlying disease severity. When choosing an antibiotic, the underlying disease severity, frequency of previous antibiotic use, as well as the severity of the exacerbation must be considered. For patients with both mild disease and mild exacerbations not requiring hospitali- zation, S. Patients with the most severe disease and severe exacerbations may have any of the organisms previously described. The risk of a pseudomonal infection must also be assessed in these individuals, and appropriate antibiotic coverage should be selected. Gagnon however, it is recommended that patients be treated for 3 to 10 days once starting antibiotics. Sputum Grams stain is generally not beneficial and sputum cultures can be reserved for those patients who fail first-line therapy. Noninvasive ventilation can be deemed successful when pH improves, dyspnea is relieved, the exacerbation is alleviated without the need for intubation, and the patient is able to leave the hospital. Invasive Ventilation Patients should be considered for invasive ventilation if they meet one or more of the following criteria: Patients with severe dyspnea, use of accessary muscles and paradoxical abdominal motion Impending respiratory failure and life-threatening acidbase disturbances, i. Patients too dyspneic to eat may require short-term tube feeding and fluid administration. The immobilized patient will benefit from subcutaneous heparin to reduce the risk of thromboembolic disease while recovering. Chest percussion, either mechanical or manual, may benefit patients producing large quantities of sputum (>25mL/day), or those with lobar atelectasis. To be discharged from the hospital, patients should not require bronchodilator treatments more often than every 4 hours. If the patient requires home oxygen, arrange- ments need to be made, and the patient and/or caregiver educated to understand the correct use of the oxygen and all of the current medications. Approximately 4 to 6 weeks after discharge from the hospital, the patient should be reevaluated regarding the need for home oxygen, inhaler technique, and overall ability to cope with the disease. Outpatient pulmonary rehabilitation soon after dis- charge has been shown to improve exercise capacity and overall health status at 3 months out of hospital. Acute Bronchitis Acute bronchitis is defined as an acute respiratory illness with a predominant cough. Up to 5% of adults in North America report an episode of acute bronchitis in the past year, approximately 90% of which 4 Management of Chronic Obstructive Pulmonary Disease Exacerbations 41 will be evaluated by their physician. This makes acute bronchitis one of the top ten acute office visits in primary care. Evaluation The evaluation of acute bronchitis involves excluding pneumonia and other more serious causes of cough. The patients comorbidities play an important role in the clinicians ability to confidently diagnose acute bronchitis. However, in the immunocompetent patient with a cough of <2 to 3 weeks duration and otherwise normal vital signs, the diagnosis of acute bronchitis can often be made with confidence. The prominent viruses implicated in acute bronchitis infecting the lower respiratory tract include influenza A and B as well as respiratory syncytial virus and parainflu- enza. It is thought that up to 5 to 10% of all acute bronchitis can be caused by bacterial organisms such as Mycoplasma pneumoniae, C. There is little or no evidence that the common organisms associated with pneumonia (S. Management Studies have revealed no reduction in the duration of symptoms associated with antibiotic treatment and, therefore, they are not recommended for treatment regardless of the duration of cough. If there is high clinical suspicion for pertussis in a patient with a prolonged cough (> 23weeks), patients should tested and treated to reduce transmission rates. The most common proven pathogen associated with acute uncomplicated bronchitis is influenza. Newer antiviral agents will help with symp- tomatology associated with influenza, however, they need to be taken within 48 42 M. Symptomatic treatments include the use of albuterol metered-dose inhalers with spacer devices for those patients with a bronchospastic component to their cough. If limited to patients with wheeze or bronchial hyperresponsiveness, -2-agonists are effective in reducing the length and severity of cough associated with acute bronchitis. The use of anticough agents, such as dextromethorphan and codeine, have a modest effect on the duration and severity of cough in patients with acute bronchitis and a cough of 2 to 3 weeks duration. Other methods for reducing cough frequency and severity include reducing dust and pollen exposure, as well as the use of humidifiers, although these have very limited evidence (but are generally low cost and very low-risk forms of treatment).
