Emphysema is one of several diseases usually labeled collectively as chronic obstructive pulmonary disease (COPD).
It’s the most common cause of death from respiratory disease in the United States; approximately 2 million Americans are afflicted with the disease. Emphysema (COPD) appears to be more prevalent in men than women. Postmortem findings reveal few adult lungs without some degree of emphysema. Causes Emphysema (COPD) may be caused by a genetic deficiency of alpha 1 -anti trypsin (AAN) and by cigarette smoking. Genetically, one in 3, 000 newborns are found with the disease, and 1% to 3% of all cases of emphysema are due to AAT deficiency.
Cigarette smoking is thought to cause 20% of the cases. Other causative factors are unknown. Complications In emphysema (COPD), complications may include recurrent respiratory tract infections, cor pulmonate, and respiratory failure. Peptic ulcer disease strikes 20% to 25% of patients with COPD.
Additionally, alveolar blebs and bullae may rupture, leading to spontaneous pneumothorax or pneumo mediastinum. Assessment findings The patient history may reveal that the patient is a long-time smoker. The patient may report shortness of breath and a chronic cough. The history may also reveal anorexia with resultant weight loss and a general feeling of malaise.
Inspection may show a barrel-chested patient who breathes through pursed lips and also uses accessory muscles. You may notice peripheral cyanosis, clubbed fingers and toes, and. Palpation may reveal decreased tactile fremitus and decreased chest expansion. Percussion may detect hyper resonance. On auscultation, you may hear decreased breath sounds, crackles and wheezing during inspiration, a prolonged expiratory phase with grunting respirations, and distant heart sounds. Diagnostic tests Chest X-rays in advanced disease may show a flattened diaphragm, reduced vascular markings at the lung periphery, over aeration of the lungs, a vertical heart, enlarged chest diameter, and large retro sternal air space.
The Essay on Tuberculosis: Infectious Disease and Tb Patients
Tuberculosis is a common, and in many cases lethal, infectious disease caused by various strains of mycobacteria, usually Mycobacteria tuberculosis. One third of the world’s population is thought to have been infected with M. tuberculosis with new infections occurring at a rate of about one per second. In 2007, there were an estimated 13.7 million chronic active cases globally, while in 2010, ...
Pulmonary function tests typically indicate increased residual volume and total lung capacity, reduced diffusing capacity, and increased inspiratory flow. Electrocardiography may reveal tall, P waves in leads II, III and a Vf; vertical QRS axis; and signs of right ventricular hypertrophy late in the disease. Red blood cell count usually demonstrates an increased hemoglobin level late in the disease when the patient has persistent severe hypoxia. Treatment Emphysema (COPD) management usually includes broncho dilators such as to promote muco ciliary clearance; antibiotics to treat respiratory tract infection; and immunizations to prevent influenza and pneumococcal pneumonia. Other treatment measures include adequate hydration and chest physiotherapy to mobilize secretions. Some patients may require oxygen therapy to correct hypoxia.
They may also require Tran tracheal to receive oxygen at home. Counseling about avoiding smoking and air pollutants is necessary.
