The diagnosis of COPD should be considered in anyone over the age of 35 to 40 who has shortness of breath, a chronic cough, sputum production, or frequent winter colds and a history of exposure to risk factors for the disease. Spirometry is then used to confirm the diagnosis. [4] [108]
ACO presents with symptoms of both asthma and COPD. [1] ACO presents in adulthood, usually after the age of 40 (after there has been significant tobacco smoke or other toxic fumes exposure), with symptoms of dyspnea (shortness of breath), exercise intolerance, sputum production, cough and episodes of symptomatic worsening known as exacerbations.
COPD is defined as a forced expiratory volume in 1 second divided by the forced vital capacity (FEV1/FVC) that is less than 0.7 (or 70%). [8] The residual volume, the volume of air left in the lungs following full expiration, is often increased in COPD, as is the total lung capacity, while the vital capacity remains relatively normal.
When associated with significant airflow limitation, emphysema is a major subtype of chronic obstructive pulmonary disease (COPD), a progressive lung disease characterized by long-term breathing problems and poor airflow. [10] [11] Without COPD, the finding of emphysema on a CT lung scan still confers a higher mortality risk in tobacco smokers ...
Onset of lung problems is typically between 20 and 50 years of age. [1] This may result in shortness of breath, wheezing, or an increased risk of lung infections. [1] [2] Complications may include chronic obstructive pulmonary disease (COPD), cirrhosis, neonatal jaundice, or panniculitis. [1]
The actual number may be significantly higher due to misdiagnosis. Typically, patients are in their forties and fifties when diagnosed, while the incidence of idiopathic pulmonary fibrosis increases dramatically after age 50. But loss of pulmonary function is commonly ascribed to old age, heart disease, or more common lung diseases. [40]
