Shortness of breath (SOB), known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct ...
Many different conditions can lead to the feeling of dyspnea (shortness of breath). DiagnosisPro, an online medical expert system, listed 497 in October 2010. [1] The most common cardiovascular causes are acute myocardial infarction and congestive heart failure while common pulmonary causes include: chronic obstructive pulmonary disease, asthma, pneumothorax, and pneumonia.
Paroxysmal nocturnal dyspnea is a serious medical symptom that can develop into worsening conditions. Many tests can be done in order to evaluate the cause of paroxysmal nocturnal dyspnea. Because it is commonly associated with heart failure, tests that may be run mainly focus on measuring the function and capability of the heart.
It’s typically triggered by exertion, like walking uphill, or emotional stress, says Dr. William Zoghbi, chair of cardiology at Houston Methodist. “It radiates,” he says.
Shortness of breath can manifest as orthopnea (inability to breathe sufficiently when lying down flat) and/or paroxysmal nocturnal dyspnea (episodes of severe sudden breathlessness at night). These are common presenting symptoms of chronic and cardiogenic pulmonary edema due to left ventricular failure.
Initial symptoms are vague and include shortness of breath, decreased exercise ability, increased recovery time, fatigue, and weakness, especially with walking uphill. [9] [3] People then develop a dry, persistent cough, and often cyanosis of the lips. Another cardinal feature of HAPE is the rapid progression to dyspnea at rest.
An undesirable side-effect of acetazolamide is a reduction in aerobic endurance performance. Other minor side effects include a tingle-sensation in hands and feet. Although a sulfonamide, acetazolamide is a non-antibiotic and has not been shown to cause life-threatening allergic cross-reactivity in those with a self-reported sulfonamide allergy.
