Berlin Definition of the Acute Respiratory Distress Syndrome (ARDS)
The Berlin definition, proposed in 2012, breaks with tradition by establishing three risk strata that are based on the degree of hypoxemia as assessed at a minimum positive end-expiratory pressure (PEEP).
Tumor, Node, Metastasis International Staging System for Lung Cancer
The Tumor, Node, Metastasis (TNM) staging system for lung cancer is an internationally accepted system used to characterize the extent of disease. The TNM system combines features of the tumor into disease stage groups that correlate with survival and are linked to recommendations for treatment.
ATS/ERS Criteria for Diagnosis of Idiopathic Pulmonary Fibrosis (IPF)
Idiopathic interstitial pneumonias (IIPs) are part of a broad, heterogeneous group of interstitial lung diseases that encompasses more than 200 acute or chronic diseases with varying degrees of inflammation or fibrosis.
GOLD Staging System for Chronic Obstructive Lung Disease (COPD) Severity
The European Respiratory Society (ERS) diagnostic criteria for COPD include the following symptoms: coughing, sputum production and/or dyspnoea, as well as a history of exposure to risk factors for COPD. The diagnosis is confirmed by a post-bronchodilator FEV1/FVC < 0.7 in spirometry, as sign of the airflow limitation that is not fully reversible.
Indications for Lung Biopsy
Patients with lesions on the chest radiograph should be discussed in a multidisciplinary meeting with a respiratory physician and radiologist at a minimum.
