Differential Diagnosis

Air hunger - the sensation of an urgent need to breathe, sensation that you cannot take in a full breath
Tachypnea - breathing rapidly
Bradypnea - breathing slowly
Eupnea - normal unlabored breathing
Orthopnea - dyspnea that occurs with lying flat
Trepopnea - an abnormal awareness of one's own breathing that is seen in one lateral position but not in the other
Paroxysmal nocturnal dyspnea - sudden, severe shortness of breath at night that awakens a person from sleep, often with coughing and wheezing.

Differentiating Shortness of Breath or Dyspnea from other Diseases

The underlying causes of dyspnea are classified as acute causes and chronic causes based on the disease course. Different causes of dyspnea include pulmonary (upper and lower airway), cardiovascular, central nervous system, toxic and metabolic, and systemic diseases.

Diseases that cause shortness of breath have to be differentiated upon the following table^[1]^[2]^[3]^[4]^[5]^[6]^[7]^[8]^[9]^[10]^[11]^[12]

Abbreviations: ABG (arterial blood gas); ACE (angiotensin converting enzyme); BMI (body mass index); CBC (complete blood count); CSF (cerebrospinal fluid); CXR (chest X-ray); ECG (electrocardiogram); FEF (forced expiratory flow rate); FEV1 (forced expiratory volume); FVC (forced vital capacity); JVD (jugular vein distention); MCV (mean corpuscular volume); Plt (platelet); RV (residual volume); SIADH (syndrome of inappropriate antidiuretic hormone); TSH (thyroid stimulating hormone); Vt (tidal volume); WBC (white blood cell);
