What is COPD? A RESPONSE Patients: typically greater than 45 years old. Respiratory symptoms include cough and TO ALTERED shortness of breath. Post-bronchodilator FEV1/FVC ratio < 0.7. RESPIRATORY History of cigarette smoking and/or exposure to other pollutants. FUNCTION A post bronchodilator ratio of FEV 1/FVC 65 years your doctor may recommend the following tests: Smoking AIDS Blood Tests: Used to confirm an infection Heart disease and try to identify the type of organism Diabetes causing the infection. However, precise Alcoholism identification isn't always possible. Asthma Chest X-ray: Helps your doctor diagnose COPD Bronchiectasis] pneumonia and determine the extent and Immunosuppressive disorders & therapy location of the infection. However, it can't tell Debility or stroke your doctor what kind of germ is causing the Coma pneumonia. Problems with swallowing Intravenous drug abuse Mena Victoria B. Conje - BSN4 - USJR Pulse oximetry. This measures the oxygen level in your blood. Pneumonia can prevent RESPIRATORY PANDEMIC your lungs from moving enough oxygen into your bloodstream. Sputum test. A sample of fluid from your lungs (sputum) is taken after a deep cough a mild to severe respiratory illness of and analyzed to help pinpoint the cause of the infection. sudden onset resulting from infection by an intluenza virus. Extremely contagious and spreads quickly Your doctor might order additional tests if you're to others. older than age 65, are in the hospital, or have Symptoms vary from person to person serious symptoms or health conditions. These may Occurs every year, usually in the fall and include: winter killing 36,000 people in U.S. CT scan. If your pneumonia isn't clearing as quickly as expected, your doctor may recommend a chest CT scan to obtain a SYMPTOMS more detailed image of your lungs. Pleural fluid culture. A fluid sample is Respiratory symptoms: taken by putting a needle between your ribs Sudden onset of: from the pleural area and analyzed to help cough determine the type of infection. sore throat difficulty breathing Fever TREATMENT Headache aching muscles Treatment for pneumonia involves curing weakness the infection and preventing complications. People Common Complications of Seasonal Flu who have community-acquired pneumonia usually Pneumonia can be treated at home with medication. Although Primary viral most symptoms ease in a few days or weeks, the Secondary bacterial feeling of tiredness can persist for a month or more Mixed viral and bacterial Specific treatments depend on the type and Exacerbation of existing disease severity of your pneumonia, your age and your Chronic pulmonary disease overall health. Cardiac conditions Less Common Complications The options include: Encephalopathy Antibiotics. Inese medicines are used to Myocarditis Pericarditis treat bacterial pneumonia. It may take time Myositis to identify the type of bacteria causing your Transverse myelitis pneumona and to choose the best antibiotic Reye's syndrome to treat it. If your symptoms don't improve, your doctor may recommend a difierent antibiotic. Cough medicine. This medicine may be used to calm your cough so that you can rest Because coughing helps loosen and move fluid from your lungs, it's a good idea not to eliminate your cough completely. In addition, you should know that very few Home Treatment of the Flu studies have looked at whether Bed rest over-the-counter cough medicines lessen Hydration-with eight ounces of fluid every coughing caused by pneumoma. It you want hour to try a cough suppressant, use the lowest Acetaminophen, ibuprofen, naproxen dose that helps you rest. Avoid aspirin when dealing with children Fever reducers/ pain relievers. You may Seeking Medical Treatment for the Flu take these as needed for fever and Persistent fever discomfort. Productive cough Increasing difficulty breathing These include drugs such as aspirin, ibuprofen Improvement, followed by relapse (Advil, Motrin IB, others) and acetaminophen (Lylenol, others).

LUNG CANCER STAGES If it is caused by left heart disease, the treatment is to optimize left ventricular function by the use of medication or to repair/replace the mitral valve or aortic valve. Patients with left heart failure or hyposemic lung diseases (groups lI or Ill pulmonary hypertension) should not routinely be treated with vasoactive agents including prostanoids, phosphodiesterase inhibitors, or endothelin antagonists, as these are approved for the different condition called primary pulmonary arterial CAUSES hypertension. Cigarette smoking To make the distinction, doctors at a minimum will Exposure to environmental pollutants conduct cardiac catheterization of the right heart, Exposure to occupational pollutants echocardiography, chest CT, a six-minute walk test, and pulmonary function testing. Using treatments for other kinds of pulmonary hypertension in ASSESSMENT patients with these conditions can harm the patient and wastes substantial medical resources.

Conje - BSN4 - USJR A RESPONSE ACUTE ISCHEMIC TO ALTERED TISSUE HEART DISEASE Coronary heart disease and PERFUSION coronary artery disease are more common names for Conditions Related to Altered Tissue Perfusion ischemic heart disease. ACUTE ISCHEMIC HEART DISEASE HEART FAILURE is chest pain or discomfort CARDIOGENIC SHOCK that recurs when part of the HYPERTENSICE CRISIS heart muscle does not CARDIOMYOPATHY receive enough blood. ARRHYMIAS "Ischemic" means a body part is not getting HEART enough blood flow and, thus, oxygen. Plaque buildup on the walls of the coronary arteries causes ischemic heart disease. Symptoms of ischemic heart disease occur more often during periods of excitement or physical exertion but can also occur suddenly and without warning. According to the Centers for Disease Control and Prevention (CDC), ischemic heart disease is the most common form of heart disease in is a hollow muscular organ in the space the United States. It is also the leading cause between the lungs and the diaphragm of heart attack. called mediastinum. weighs approximately 300 g or 10.6 oz This disease most often occurs when pumps blood to the tissues, supplying cholesterol particles in the blood build up on them with oxygen and other nutrients. the walls of the arteries that supply blood to the has 3 layers heart muscle. Eventually, deposits called inner layer or endocardium plaques may form. These plaques are a result middle layer or myocardium of inflammation. exterior layer or epicardium the heart is encased in a thin, fibrous These deposits cause the arteries to narrow. sac called the pericardium. This narrowing can block the flow of blood. This reduces the amount of oxygenated blood The space between 2 layers ( pericardial reaching the heart muscle. This process is space) is normally filled with about 20 ml of called atherosclerosis. fluid- which lubricates the surface of the heart and reduces friction during systole. Atherosclerosis is the buildup of fats, cholesterol and other substances in and on the artery walls. This buildup is called plaque. What does "ischemic" mean? "Ischemic" means that is not getting enough blood flow and, because of this, not enough oxygen will be supplied. When this happens to the heart, it is called ischemic heart disease. This disease is also known as coronary heart disease and coronary artery disease. Mena Victoria B. Conje - BSN4 - USJR If you have ischemic heart disease, you may have chest pain or discomfort during exertion Serious symptoms that or excitement. These are times when the heart might indicate a life requires greater blood flow. threatening condition "Angina" the name for this type of chest pain. Ischemic heart disease can The signs and symptoms of this disease may cause a heart attack. Seek develop slowly as plaques gradually block the immediate medical care arteries. However, sometimes the symptoms (call 911) for any of these arise quickly if an artery suddenly becomes serious symptoms, including: blocked. chest pain or pressure, typically on the Some people with ischemic heart disease have left side of the body, which may radiate no symptoms at all. This is called "silent to the jaw, neck, shoulder, or arm ischemia." clammy skin nausea with or without vomiting A heart attack can be the first sign of a problem rapid breathing or shortness of breath for someone who has schemia. Other people dizziness or near fainting may first have severe chest pain and shortness of breath. Lifestyle changes, medications, and sometimes surgery can successfully treat ischemic heart disease. You can reduce your risk of this disease by following heart-healthy practices. This includes eating a low-fat, low-sodium diet, being physically active, not smoking, and maintaining a moderate body weight. CAUSES SYMPTOMS In ischemic heart disease, narrowing Ischemic heart disease decreases the amount coronary arteries reduce the amount of of blood flowing through the coronary arteries. oxygenated blood flowing to the heart muscle. These arteries carry oxygen-rich blood to the Without enough blood flow, the heart muscle heart muscle. does not receive the amount of oxygen it needs to function properly. Reduced blood and oxygen to the heart can cause varying symptoms. Symptoms can differ Ischemic heart disease occurs most often in from person to person. people who have atherosclerosis. This is a buildup of plaque on the walls of the coronary When symptoms occur, common symptoms arteries. However, the reduced blood supply include can also be due to blood clots, coronary artery chest pain spasms, or severe illnesses that increase the chest pressure heart's need for oxygen. shortness of breath may feel as if pain, pressure, heaviness, or tightness starting in the chest is spreading to the arms, back, or other areas may feel like gas or indigestion occur repeatedly in similar episodes occur when the heart must work harder, usually during physical esertion subside with rest or medicine usually last a short time, about 5 minutes or less Mena Victoria B.

Conje - BSN4 - USJR However, the heart failure may also cause by other disorders. COMPLICATIONS The causes of heart failure can be Possible complications of ischemic heart divided into three groups: disease include: Abnormal loading conditions arrhythmia, which is an irregular heart Abnormal muscle function rhythm Conditions or diseases that limit chronic angina ventricular filling congestive heart failure recurrent heart attack 1. Abnormal loading conditions is HEART FAILURE (CHF) associated with any condition that Heart Failure, also known as consertive increases either the pressure or the heart failure, is a significant cardiac functional volume load of the ventricle.

Mena Victoria B. Conje - BSN4 - USJR Coronary artery disease. Atherosclerosis of the coronary arteries is the primary cause of HF, and PREVENTION coronary artery disease is found in more than 60% of the patients with HF. Prevention of heart failure mainly lies in Ischemia. Ischemia deprives heart cells lifestyle management of oxygen and leads to acidosis from Healthy diet, Avoiding intake of fatty the accumulation of lactic acid. and salty foods greatly improves the Cardiomyopathy. HF due to cardiovascular health of an individual cardiomyopathy is usually chronic and Engaging in cardiovascular exercises progressive. thrice a week could keep the Systemic or pulmonary hypertension. cardiovascular system up and running Increase in afterload results from smoothly hypertension, which increases the workload of the heart and leads to Smoking cessation.

NURSIMG MANAGEMENT Despite advances in the treatment of HIP, morbidity and mortality remain high. Nurses hare a major impact on outcomes for patients with HF. NURSIMG ASSESSMENT The nursing assessment for the patient with HF focuses on observing for the effectiveness of therapy and for the patient's ability to understand and implement self-management strategies. Health History : ➔ Asses the signs and symptom such as dyspnea, shortness of breath, fatigue, edema. ➔ Assess for sleep disturbances, specially sleep suddenly interrupted by shortness of breath ➔ Explore the patient's understanding of HF, self management strategies, and the ability and willingness to adhere to those strategies Physical Examination ➔ Auscultate the lungs for presence of crackles and wheezes ➔ Auscultate the heart for the presence of an S3 heart sound. ➔ Assess JVD for presence of distention. ➔ Evaluate the sensoriums and level of consciousness. ➔ Assess the dependent parts of the patient's body for perfusion and edema. ➔ Assess the liver for hepatojugular reflux. ➔ Measure the urinary output carefully to establish a baseline against which to assess the effectiveness of diuretic therapy. ➔ Weigh the patient daily in the hospital or at home Mena Victoria B.
