Tachypnea, also spelt tachypnoea, is a respiratory rate greater than normal, resulting in abnormally rapid and shallow breathing. [1]In adult humans at rest, any respiratory rate of 12–20 per minute is considered clinically normal, with tachypnea being any rate above that. [2]
Tachypnea – increased breathing rate; Orthopnea – Breathlessness in lying down position relieved by sitting up or standing; Platypnea – Breathlessness when seated or standing, relieved by lying flat; Trepopnea – Breathlessness when lying flat relieved by lying in a lateral position; Ponopnea – Painful breathing
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 ...
The most common symptoms of POTS are rapid heart rate within 10 minutes of standing or sitting up, lightheadedness and fainting, fatigue, brain fog, nausea, and shortness of breath.
Inappropriate sinus tachycardia is primarily a diagnosis of exclusion. [7] Upon exertion, an inappropriate heart rate response of sinus tachycardia can be seen in some inborn errors of metabolism that result in metabolic myopathies, such as McArdle disease (GSD-V) [11] [12] and hereditary myopathy with lactic acidosis (Larsson–Linderholm ...
The symptoms of TACO can include shortness of breath , low blood oxygen levels , leg swelling (peripheral edema), high blood pressure (hypertension), and a high heart rate (tachycardia). [ 3 ] It can occur due to a rapid transfusion of a large volume of blood but can also occur during a single red blood cell transfusion (about 15% of cases). [ 2 ]
In a person who does not tolerate exercise well, physical activity may cause unusual breathlessness , muscle pain , tachypnoea (abnormally rapid breathing), inappropriate rapid heart rate or tachycardia (having a faster heart rate than normal), increasing muscle weakness or muscle fatigue; or exercise might result in severe headache, nausea ...
Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be acute or chronic. In clinical trials, the definition of respiratory failure usually includes increased respiratory rate, abnormal blood gases (hypoxemia, hypercapnia, or both), and evidence of increased work of breathing.
