Complications of Chronic Lung Hyperinflation
Chronic lung hyperinflation not only presents as a complication on its own, but it can also give rise to various other issues. The discomforting symptoms it induces may lead individuals to shy away from physical activity, ultimately resulting in a deterioration of their overall physical condition. Furthermore, impaired lung emptying and insufficient inhalation can lead to fatigue and failure of the respiratory muscles. In addition, hyperinflation is linked to stress and dysfunction of the left ventricle of the heart, potentially contributing to the development of cardiovascular disease.
Diagnosis of Lung Hyperinflation
Diagnosing lung hyperinflation involves the measurement of functional residual capacity (FRC) and residual volume (RV) of the lungs. FRC refers to the volume of air that remains in the lungs during normal expiration, while RV is the volume of air that remains after maximum exhalation. Medical professionals typically use a spirometer, a device that a person breathes into, to measure FRC and RV. However, the most accurate method for diagnosing lung hyperinflation is through body plethysmography. Although alternative respiratory function tests may be used, their results are generally less reliable.
