Shortness of breath (SOB), also medically 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 ...
Shallow breathing, thoracic breathing, costal breathing or chest breathing [1] is the drawing of minimal breath into the lungs, usually by drawing air into the chest area using the intercostal muscles rather than throughout the lungs via the diaphragm. Shallow breathing can result in or be symptomatic of rapid breathing and hypoventilation.

Labored breathing is distinguished from shortness of breath or dyspnea, which is the sensation of respiratory distress rather than a physical presentation. Still, many [2] simply define dyspnea as difficulty in breathing without further specification, which may confuse it with e.g. labored breathing or tachypnea (rapid breathing). [3]
Hyperventilation syndrome (HVS), also known as chronic hyperventilation syndrome (CHVS), dysfunctional breathing hyperventilation syndrome, cryptotetany, spasmophilia, latent tetany, and central neuronal hyper excitability syndrome (NHS), is a respiratory disorder, psychologically or physiologically based, involving breathing too deeply or too rapidly (hyperventilation).
Mouth breathing, medically known as chronic oral ventilation, is long-term breathing through the mouth. It often is caused by an obstruction to breathing through the nose, the innate breathing organ in the human body. [3] [4] [5] However, by the early 20th century, the term "mouth-breather" had developed a pejorative slang meaning connoting a ...
