===Features Specific for Congestive Heart Failure===
[[Chronic obstructive pulmonary disease]] (COPD) may be confused with congestive heart failure due to similar presentations like [[wheezing]] and shortness of breath. Features specific to congestive heart failure are:
* [[Orthopnea]]
* [[Paroxysmal nocturnal dyspnea]]
* Fine [[crackles]] on ausculatation
* Chest X ray findings of cardiac enlargement, pulmonary congestion ([[Kerley B lines]], and [[pleural effusion]])
* The peak expiratory flow is low in COPD whereas there is higher flow in heart failure
* Comet-tail sign on ultrasonography is a good indicator of heart failure–related dyspnea <ref name="pmid22188907">{{cite journal |author=Prosen G, Klemen P, Strnad M, Grmec S |title=Correction: Combination of lung ultrasound (a comet-tail sign) and N-terminal pro-brain natriuretic peptide in differentiating acute heart failure from chronic obstructive pulmonary disease and asthma as cause of acute dyspnea in prehospital emergency setting |journal=[[Critical Care (London, England)]] |volume=15 |issue=6 |pages=450 |year=2011 |month=December |pmid=22188907 |doi=10.1186/cc10511 |url=http://ccforum.com/content/15/6/450 |accessdate=2012-03-05}}</ref>
===Features Specific for Bronchiectasis===
* Copious purulent sputum
* Coarse crackles
* Clubbing
* CT findings suggestive of Bronchiectasis.
===Features Specific for Bronchiolitis Obliterans===
* History of collagen vascular disease.
* Young patient usually without a history of smoking
* CT scan shows finding of mosaic attenuation and no evidence of emphysema.
===Features Specific for Chronic Asthma===
* Chronic asthma responds well to bronchodilators.
* Normal diffusion capacity of lung on pulmonary function test.
