A healthy person does not notice how he breathes. He thinks of it when he feels that he “No air”, “Close to the chest”.
Dyspnea occurs whenever the body seeking to maintain the necessary for life the oxygen level in the blood, breathing accelerates reduction.
A signal of the lack of oxygen (the main suppliers of the heart and lungs) at the wandering nerve enters the brain and activates the respiratory center, which, in turn, gives the command to accelerate the pace of breathing. Shortness of breath is primarily a reaction to increased physical activity: we are increasing the pace of walking, trying to catch up with the departing bus, etc. After such tests have breath — to breath. The restoration of normal breathing sometimes takes time.
The method of dealing with this shortness of breath is simple, even banal: it is necessary to do physical exercises, walk more. The person who most of his life at home and in the office, muscles are working at half strength, their cuts are not enough to support the work of the heart. This explains why when you run the same complexity of the task, the shortness of breath in physically well-trained people are less pronounced than in those who lead a sedentary lifestyle.
Shortness of Breath – Dangerous or Not?
When shortness of breath should alert? For example, you always walk the same route, 10-15 minutes at their usual pace. And then, one day, you notice that go harder: lacking breathing, you need to stop and stand for a bit. The movement stops — the first sign of trouble, signal that in response to regular physical activity increases the breathing rate (normal per minute should be 14-16).
Causes problems with breathing — shortness of breath — can be obesity, and anemia (low blood hemoglobin), but very likely the most frequent culprits — diseases of the cardiovascular system and lungs. Lungs don’t hurt. Their disadvantage can be judged only by indirect signs, including shortness of breath. But dyspnea strife. So, when the bronchi are clogged with phlegm, a person feels that, no matter how he tried to breathe, he is given with great difficulty. The same pattern can occur with tumors of the respiratory tract. If the cause of dyspnea — bronchospasm, difficulty arises already when you exhale. It can be so strong that it gives rise to a sense of suffocation.
Treatment of Dyspnea
To understand exactly where the disturbed air passage, conduct a special study — definition of external respiration function. In difficult cases, resorting to bronchoscopy. A thin probe is located at the end of the optical system allows you to directly examine the trachea and bronchi of all calibers. Shortness of breath caused by disorders of the cardiovascular system, is also manifested as a feeling of lack of air, the inability to breathe deeply. She is a frequent companion of coronary heart disease.
But sometimes shortness of breath can signal acute circulatory failure or pulmonary edema. Ultrasound diagnosis of the heart, the daily study of heart rate, electrocardiographic monitoring and other studies will help determine the true cause of the rapid breathing in heart disease. If dyspnea occurs at rest, it is a bad sign, a signal of serious violations in the body. Sudden and rapidly increasing, it may be due to embolism (blockage) of blood vessels of the lungs, or rupture of the lung tissue. Its appearance at night — often the result of disruption of heart rhythm, congestive heart failure, heart attack or asthma.
In all these cases required emergency medical care. Shortness of breath often occurs on the background of emotional stress. A strong emotion, anger, anxiety, fear stimulate the production of adrenaline. Once in the blood, it causes the body to operate in the mode of hyperventilation (to drive through my lungs too much air). The storm generated hormonal signals in the Central nervous system, which, aroused, often forcing to be reduced muscles of respiration. The higher passions, the more shortness of breath. Emotion stimulates activity not only lungs, but heart. The increase in heart rate is felt as palpitations. As soon as the stressful situation goes away, and normal breathing. Shortness of breath can accompany a number of diseases not directly affecting the organs of respiration and circulation. So, it often occurs in hyperthyroidism (excess thyroid hormone), diabetes. Some medications can also cause shortness of breath. Sudden Dyspnea in a child can be connected with the contact of a foreign body in the respiratory tract.
So if shortness of breath began to appear when a normal load, alone, at night, or it is accompanied by other unpleasant sensations (pain in the heart, abnormal heart rhythm, dizziness, weakness, shortness of breath or exhalation), without delay, go to the doctor.
