Possible Causes for Decreased Lung Compliance

Restrictive Lung Disease

Common causes of decreased lung compliance are pulmonary fibrosis, pneumonia and pulmonary edema. [medicine.mcgill.ca]

Parenchymal Disease In some cases, the pulmonary parenchyma exhibits pathology which causes decreased lung compliance and thus requirements for greater pressures to expand [pathwaymedicine.org]

Respiration Laboratory T heory > Lung Diseases In a restrictive lung disease, the compliance of the lung is reduced, which increases the stiffness of the lung and limits expansion [medicine.mcgill.ca]

Acute Respiratory Distress Syndrome

Hallmarks of ARDS include hypoxemia and decreased lung compliance, increased work of breathing, and impaired gas exchange. [ncbi.nlm.nih.gov]

It is characterized by the acute onset of diffuse, bilateral pulmonary infiltrates secondary to noncardiogenic pulmonary edema, refractory hypoxia, and decreased lung compliance [ncbi.nlm.nih.gov]

Also decrease lung compliance is another feature of ARDS due to decrease area of aeration and fibrosis. [youtube.com]

Pulmonary Contusion

This blunt lung injury develops over the course of 24 hours, leading to poor gas exchange, increased pulmonary vascular resistance and decreased lung compliance. [prep4usmle.com]

Chest Trauma Pulmonary Contusion Pulmonary contusion is an injury to lung parenchyma, leading to oedema and blood collecting in alveolar spaces and loss of normal lung structure [trauma.org]

Large hemorrhages from contusions may lead to ventilation/perfusion mismatch, pulmonary edema, and decreased lung compliance. 6, 7 Table: Characteristics of Pulmonary Contusion [pulmonarychronicles.com]

Pigeon Breeder's Lung

The functional abnormality is essentially a restrictive ventilatory disturbance with impairment of gas transfer and decrease in lung compliance. [tandfonline.com]

The clinical features, common to these conditions, consist of pulmonary (dyspnoea, cough, thoracic aches, fine crepitations at both lung bases) and systemic (fever, chills [tandfonline.com]

Ventilation Pneumonitis

Depending on the pattern of ventilation a patient may suffer from restrictive lung disease (impairing lung ventilation) caused by decrease in the lung compliance. [intellectbreathing.com]

Neutrophils damage the vascular endothelium and alveolar epithelium, leading to pulmonary edema, hyaline membrane formation, decreased lung compliance, and difficult air exchange [aafp.org]

PEEP=the higher of PEEPi and PEEPe - dynamic effective compliance reduced by decreases in lung or chest wall compliance or increases in airway resistance while static compliance [aic.cuhk.edu.hk]

Morbid Obesity

Definition The overall respiratory problem is one of restrictive lung disease. Chest wall and lung compliance are decreased from the heavy layer of fat. [openanesthesia.org]

Also, excessive adipose tissue over the chest decreases the chest wall compliance, and increased abdominal mass forces the diaphragm upwards and reduces lung volumes. [openanesthesia.org]

Because awake MO patients already have severe alterations of their respiratory mechanics (10) (decreased chest wall and lung compliance, decreased functional residual capacity [journals.lww.com]

Desquamative Interstitial Pneumonia

Lung function showed decreased pulmonary compliance; lung biopsy showed desquamative interstitial pneumonitis. [ncbi.nlm.nih.gov]

Pulmonary Fibrosis

Additionally, the static pressure-volume curve is shifted downward and to the right as a result of decreased lung compliance. [physio-pedia.com]

Fibrosis leads to decreased lung compliance and increased elastic recoil, which increases the overall work of breathing and inefficient exchange of gases. [medical-dictionary.thefreedictionary.com]

The replacement of normal lung with scar tissue causes irreversible decrease in oxygen diffusion capacity, and the resulting stiffness or decreased compliance makes pulmonary [en.wikipedia.org]

Technetium-DTPA Clearance Study: has been used to predict prognosis in some centers (more rapid clearance indicates more disrupted epithelial integrity consistent with interstitial lung [mdnxs.com]

Chronic Obstructive Pulmonary Disease

The tissue damage in the lungs leads to poor compliance (the elasticity, or ability of the lung tissue to expand). [medicinenet.com]

Emphysema causes a decrease in elastic recoil pressure and an increase in lung compliance. [doi.org]

The decrease in elasticity of the lungs means that oxygen in the air cannot get by obstructions (for example, thick mucus plugs) to reach air spaces (alveoli) where oxygen [medicinenet.com]

Acute Interstitial Lung Disease

Normal lung parenchyma is interspersed with areas of decreased compliance and extensive parenchymal alterations. [thoracicmedicine.org]
