In addition, lay rescuers typically have difficulty attempting to establish an airway and ventilation of the lungs, consuming needed time to establish blood flow with chest compressions. The phrase "push hard and push fast" encourages rescuers to compress *Section cowritten with Roger D. Following a shock, chest compressions are immediately resumed unless the victim 532 12 - Which Therapy for Which Condition If monomorphic wave form defibrillators are used, 360-Joule shocks are recommended. For biphasic wave forms, this is device specific ranging from 120-200 Joules with subsequent shocks at the same or higher energy levels. The best ratio of chest compression to ventilation is not clear and, as stated, ventilation is not recommended for bystanders. The efficacy of amiodarone has been established by two clinical trials in patients with out-of-hospital cardiac arrest. No recommendations for or against precordial thumps have been made, which in some studies led to a deterioration in cardiac rhythm. The ethics of when to stop the "loops" and when not to resuscitate are becoming increasingly complex. The increasing use of capnography during cardiac arrest provides readily measurable and objective data to guide decision making. The patient will have been urgently hospitalized and central nervous injury and cardiogenic shock are the major risks. Nevertheless, it makes sense to consider an ischemic cause in such patients, and aggressively to treat 534 12 - Which Therapy for Which Condition Empirical b-blockade is the prime longterm antiarrhythmic treatment unless contraindicated, whereupon empirical amiodarone is the next choice.

Many of these pulmonary disorders appear simultaneously in the cancer setting and patients frequently succumb to cardiac failure as the end-point of a complex series of cardiopulmonary interactions skin care untuk kulit berjerawat purchase 30 mg acnotin mastercard. Thus skin care brands buy cheap acnotin 40mg online, an understanding of the interactions between the circulatory and pulmonary organ systems is central to the optimal treatment of the cancer patient with lung disease acne vulgaris treatments buy cheap acnotin on line. This chapter will review some of the common mechanical and physiologic consequences of cancer and its therapy on cardiopulmonary function skin care 77054 safe 30 mg acnotin. Several broad areas will be emphasized, including (1) pulmonary vascular abnormalities, (2) pneumotoxicity caused by chemotherapeutic agents and radiation, (3) pulmonary infections, (4) direct and indirect effects of intrapulmonary tumors, (5) neurologic and chest wall disorders, and (6) critical care interventions. Metabolic disorders: glycogen storage disease, Gaucher disease, thyroid disorders. Others: tumoral obstruction, fibrosing mediastinitis, chronic renal failure on dialysis * Simonneau, 2009 #433. Malignancy, hypercoaguability, inflammation, and other conditions that compromise hepatic flow may lead to hepatic portal vein thrombosis and portal hypertension. While the duration of portal hypertension appears to influence the development of portopulmonary hypertension, correlations between the severity of portal hypertension and subsequent development of pulmonary hypertension have not been firmly established. Morphologic changes, including medial hypertrophy, plexiform arteriopathy, intimal fibrosis, adventitial proliferation, intraarterial thrombus, and fibrinoid necrosis of small arteries have been described. The coexistence of pulmonary hypertension with portal hypertension worsens the overall prognosis. A mean survival of only 15 months was reported in one study, with a 50% 6-month mortality in the absence of pharmacological interventions. Antiretroviral therapy results in only modest improvements in pulmonary pressures. Early diagnosis and the application of new treatment strategies have resulted in manageable disease in many cases with improvements in both quality of life and survival. The histologic hallmark of this rare disorder is represented by diffuse fibrous occlusion predominantly of the postcapillary venules and small veins within the lobular septa. Medial hypertrophy of the pulmonary arteries is seen in 50% of patients with this disorder, however, arteritis and plexiform lesions are typically absent. Pulmonary hemosiderosis, interstitial edema and lymphatic dilatation, are prominent features of both disorders. Ground glass opacities, septal thickening, mediastinal adenopathy, pleural effusions and reticulonodular patterns are common on chest imaging studies. Hemosiderin-laden macrophages are frequent findings on bronchoscopic examinations. Hemoptysis occurs infrequently in both disorders and is rarely massive or life-threatening. Pulmonary function studies typically demonstrate a restrictive lung defect along with a reduced single-breath diffusing capacity for carbon monoxide. Kerley B lines, a result of transudation of fluid into the interstitium and enlargement of lymphatic channels are frequent findings. The pleural effusions are typically transudates and result from elevation of pulmonary capillary and visceral pleural capillary hydrostatic pressures. Other radiographic findings include engorgement of central pulmonary arteries and patchy airspace disease. Bronchoscopic airway inspection reveals hyperemic lobar and segmental bronchi with vascular engorgement that may manifest as longitudinal streaks along the distal bronchial walls. The diagnosis requires pathologic confirmation, although bronchoscopically-obtained lung biopsies may be associated with significant bleeding and are not recommended. Findings on surgical lung biopsy specimens, including intimal fibrosis that predominantly involves the small post-capillary pulmonary veins and the absence of plexiform lesions helps to clinch the diagnosis. A definitive diagnosis may, however, provide important prognostic information and may impact decisions regarding the considerations for lung transplantation. These agents may, in fact, worsen the overall cardiopulmonary status by precipitating florid and sometimes fatal pulmonary edema. Thus, vasodilator therapy in this form of pulmonary edema should be used with extreme caution. Other forms of therapy, including immunosuppressive medications with glucocorticoids and antimetabolites have been employed. Data regarding the utility of these treatment regimens are limited to small case reports and, thus, firm conclusions regarding efficacy cannot be drawn. The role of anticoagulation in the treatment of these patients remains largely unstudied. Reported one-year mortality rate of 72% yields testimony to the overall poor prognosis of patients with this disease. Pulmonary venous hypertension may also occur as a result of compression of the pulmonary vasculature by bulky mediastinal disease. The signs and symptoms of this type of pulmonary venous hypertension are dictated by the mediastinal structures that are involved. In addition to pulmonary venous hypertension, obstruction of the heart and great vessels may lead to superior vena cava syndrome, constrictive pericarditis. Massive hemoptysis secondary to invasion of the bronchus by friable fibrous tissue, airway obstruction, or pulmonary venous hypertension has also been reported. Most causes of fibrosing mediastinitis in the United States have been linked to Histoplasma capsulatum infection. Rarely, fibrosing mediastinitis has also been implicated in other infections, including Aspergillous, Mycobacterium tuberculosis, Blastomycosis, Mucormycosis, and Cryptococcosis. Surgical debulkment of large mediastinal masses has been tried with variable results. The feasibility of surgical therapy is frequently mitigated, however, by extensive mediastinal calcification, fibrosis, and collateral vessel formation. Pulmonary venous hypertension secondary to mediastinal compression and/or fibrosis generally heralds a poor prognosis.

Symptoms of constriction arise from elevation of either left- or right-sided filling pressures delex acne buy 40 mg acnotin otc. Gradually worsening weakness acne at 40 generic acnotin 20 mg with mastercard, fatigue acne 5 weeks pregnant buy 30 mg acnotin amex, and dyspnea on exertion are prominent acne 2009 dress order acnotin master card, but highly nonspecific in the cancer patient. Lower extremity edema, abdominal congestion, and ascites are common, and are often confused with heart failure or tamponade. Physical exam findings mimic those seen in right-sided heart failure, with elevated jugular venous pressure, hepatomegaly (sometimes pulsatile), and peripheral edema. An S3 may be present, in this setting referred to as a pericardial knock, and is due to rapid ventricular filling. Chest X-ray may reveal cardiomegaly, pericardial calcification, an enlarged azygous vein, and pleural effusions. Diagnosis of constriction really requires the hemodynamic data available from echocardiography and catheterization, however. Echocardiography can reveal several aspects of pericardial constriction, but the findings can be subtle, and the interpreting cardiologist must have a reasonable index of suspicion to make the diagnosis. Pericardial anatomy can be visible, but image quality is often limited by the high echogenicity of the pericardium, especially when calcification is present. The interventricular septum can show a characteristic "bounce" corresponding to the rapid ventricular filling in early diastole. An M-mode through the posterior wall of the left ventricle sometimes shows separate densities corresponding to parietal and visceral pericardium that are adherent to the posterior wall and move with the myocardium, a phenomenon known as "tram-tracking" (Figure 16-13B). Doppler examination of mitral inflow reveals a restrictive filling pattern of severe diastolic dysfunction, including E/A ratio > 2 and very rapid deceleration time. Unlike restrictive cardiomyopathy however, tissue Doppler measurements of the mitral annulus remain normal or are increased. Ventricular interdependence is the most specific finding, and is demonstrated by exaggerated changes to the inflow velocities with respiration. Mitral inflow velocities decrease with inspiration and increase with expiration, and tricuspid velocities conversely increase with inspiration and decrease with expiration. Left and right ventricles both show a characteristic diastolic pressure tracing-"dip and plateau"- which reflects rapid early filling followed by abrupt cessation of filling due to a rigid unexpandable heart (Figure 16-14A). Simultaneous right atrial and pulmonary capillary wedge tracings can demonstrate ventricular interdependence with one rising while the other falls. In practice, diagnosis of pericardial constriction is not straightforward, as many of the above findings can also be seen with tamponade, restrictive cardiomyopathy, or right ventricular failure. Treatment of pericardial constriction is surgical, and complete pericardiectomy is required, usually through a median sternotomy approach. The surgery is long and technically challenging due to adherent fibrotic debris, and can be complicated by severe bleeding, myocardial damage, arrhythmias, and hypotension. Good outcomes rely on careful patient selection, and it is the rare patient with metastatic cancer who is able to tolerate such a procedure.
