Luftinfångning

Luftinfångning, often translated as "air trapping" or "air trapping syndrome" in English, is a pulmonary condition characterized by the incomplete emptying of air from the lungs during exhalation. This means that a significant volume of air remains trapped in the alveoli even after a normal breath out. This trapping can occur due to a narrowing or collapse of the airways, preventing air from being expelled efficiently.

Several underlying respiratory diseases can lead to luftinfångning. Chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis, is a common culprit. Asthma, particularly when poorly controlled, can also cause air trapping due to bronchoconstriction and inflammation of the airways. Other conditions, such as bronchiolitis obliterans, can also result in this phenomenon.

The consequences of luftinfångning can include shortness of breath, particularly during physical activity, a feeling of chest tightness, and a reduced lung capacity. In severe cases, it can contribute to hyperinflation of the lungs, where the chest cavity becomes permanently expanded, making breathing even more difficult. Diagnosis typically involves pulmonary function tests, such as spirometry, which can measure the volume of air exhaled and the speed at which it is exhaled. Treatment strategies focus on managing the underlying condition causing the air trapping and may include bronchodilators to open airways, anti-inflammatory medications, and pulmonary rehabilitation.
