What to Know About Pulmonary Hyperinflation.

Hyperinflation of the lungs is a common complication of c hronic obstructive pulmonary disease COPD. It happens when too much air gets trapped inside your lungs. Chronic obstructive pulmonary disease COPD is a group of lung diseases caused by long-term exposure to gases or irritants, including those found in cigarette smoke. These substances cause chronic inflammation and damage lung tissue. Over time, inflammation can narrow your airways, limit airflow, and make it harder to breathe. Without proper airflow, air can get trapped in your lungs. This can happen no matter how mild or severe your COPD symptoms are.

Hyperinflated lungs refer to a medical condition where the lungs are expanded beyond their usual size due to trapped air. Various internal systemic factors can reduce the ability of the lungs to exhale the proper amount of air, leading to overinflation. Especially, health care professionals associate hyperinflated lungs with chronic obstructive pulmonary disease COPD. Pulmonary hyperinflation is the medical name for hyperinflated lungs. Furthermore, overinflated lungs restrict the amount of air you inhale, depleting circulating oxygen in the body. This results in reduced life expectancy due to respiratory issues and cardiac complications. In this blog, we will comprehensively examine the hyperinflated lungs causes, symptoms, diagnosis, and treatment. It holds significance for COPD patients as it contributes to dyspnea, increased morbidity, exercise tolerance and overall reduction in physical activity. Additionally, pharmacological and non-pharmacological therapies have demonstrated efficacy in minimizing hyperinflation and delaying the onset of ventilatory restriction. However, some COPD patients suffer from dynamic hyperinflation of the lungs which causes a reduction in hyperinflated lungs life expectancy. Dynamic hyperinflation occurs when a new breath is inhaled before the lung has reached its static equilibrium volume. In simple terms, the lungs fail to exhale completely before they inhale a new breath of air, leading to the trapping of air in the lungs and causing the patients to inhale and exhale to occur when the lungs are full. This figure shows COPD patient is green line, and the healthy individual is blue line. In normal breathing, the lungs exhale and inhale the same amount of air with each breath. This means that the amount of air remaining in the lungs after exhalation known as functional residual capacity FRC remains constant.

As it was discussed above DH both increases the pressure changes needed to achieve a given tidal volume and decreases the ability of the respiratory muscles to generate pulmonary hyperaeration treatment pressure Marshall ; Kim et al ; Similowski et al ; Polkey et al

Hyperinflated lungs happen when some air gets trapped in the lungs when breathing out. The lungs also get stiff and less stretchy, making it harder to push air out. Hyperinflated lungs can make it difficult to catch your breath. And breathing gets worse during physical activity. Chronic obstructive pulmonary disease COPD often leads to hyperinflated lungs.

This can contribute to shortness of breath dyspnea , which is the primary symptom of COPD. There are two types of hyperinflation:.

Pulmonary hypertension is hard to diagnose early because it's not often found during a routine physical exam. Even when pulmonary hypertension is more advanced, its symptoms are similar to those of other heart and lung conditions. To diagnose pulmonary hypertension, a health care professional examines you and asks about your symptoms. You'll likely be asked questions about your medical and family history. Sound waves are used to create moving images of the beating heart.

Qual Life Res. Respiratory mechanics and the intrathoracic pressure swinging are different during the tidal and maximal expiratory efforts and exercise may result in changes in airways tone Beck et al Arch Bronconeumol. Effect of bovine pericardial strips on air leak after stapled pulmonary resection. Furthermore, individuals with pre-existing respiratory conditions, such as asthma or bronchiectasis, are also at risk. Hyperinflation is associated with increased respiratory rate and is a more sensitive measure of cystic fibrosis lung disease during infancy compared to forced expiratory measures. In another study the opposite was observed Pellegrino Pediatr Pulmonol. Effects of dihydrocodeine, alcohol, and caffeine on breathlessness and exercise tolerance in patients with chronic obstructive lung disease and normal blood gases. In accordance with this renewed interest, a provocative hypothesis has been put forward recently that proposes that the transition from peripheral airways disease to COPD follows three pathophysiological stages defined by the severity of expiratory flow limitation: In Stage I, closing volume eventually exceeds the functional residual capacity FRC ; in Stage II tidal volume expiratory flow limitation EFL develops; and in Stage III, DH increases to a point that produces dyspnea and exercise limitation. In addition, they are available by prescription and can help treat various lung conditions such as chronic obstructive pulmonary disease COPD , asthma, cystic fibrosis, and bronchiolitis. The functional consequences of these abnormalities are expiratory airflow limitation and dynamic hyperinflation, which then increase the elastic load of the respiratory system and decrease the performance of the respiratory muscles. Heart Lung. Hyperinflated lungs are expanded beyond their normal size because there is air trapped in them.
