Pneumothorax is defined as the abnormal presence of air within the pleural space (cavity) that results in the partial or complete collapse of a lung. It can occur spontaneously or due to a traumatic event. Symptoms can vary from a nondescriptive complaint of shortness of breath or chest pain to complete cardiopulmonary collapse. Diagnosis is based on a(More)
Venous thromboembolism (VTE) includes deep venous thrombosis (DVT) and pulmonary embolism (PE). The clinical presentation of VTE is nonspecific and requires confirmatory testing. The most common diagnostic tool for DVT is duplex ultrasonography since it is a noninvasive test with high accuracy. Contrast venography is considered the gold standard modality to(More)
Respiratory failure is a condition in which the respiratory system fails in one or both of its gas exchange functions. It is a major cause of morbidity and mortality in patients admitted to intensive care units. It is a result of either lung failure, resulting in hypoxemia, or pump failure, resulting in alveolar hypoventilation and hypercapnia. This article(More)
Venous thromboembolism (VTE) has a wide range of clinical presentations. Deep venous thrombosis may occur in upper or lower extremities or in visceral veins. Extremity deep venous thrombosis usually manifests with unilateral painful swelling in the limb, while visceral deep venous thrombosis manifestations vary on the basis of the involved organ. Pulmonary(More)
Venous thromboembolism is the formation of a blood clot in the vein. It mainly consists of 2 life-threatening conditions-deep venous thrombosis and pulmonary embolism. Deep venous thrombosis is a potentially dangerous condition with grave sequelae, the worst of which is pulmonary embolism. Venous thromboembolism can also lead to multiple other conditions(More)
Venous thromboembolism (VTE) can present in a variety of different clinical settings and in a diverse, comorbid patient population, both of which will guide the clinician toward the appropriate therapeutic response. Patients who present with pulmonary embolism are at risk for hemodynamic instability, recurrence of VTE, cardiac comorbidities, and increased(More)
In the United States, venous thromboembolism is associated with high mortality and morbidity affecting as many as 900 000 people (1-2 per 1000) each year. Estimates suggest that 60 000 to 100 000 Americans die of deep venous thrombosis/pulmonary embolism and 10% to 30% die within 1 month of diagnosis, with sudden death being the first symptom in(More)
Acute pneumonia is an active infection of the lungs that results when an individual at risk gets exposed to a particular microbiological pathogen. Acute pneumonia is the leading cause of death in the United States that is attributable to an infection. The risk factors, pathogenesis, and microbiological organisms involved differ if the pneumonia develops in(More)
