Pulmonary interstitial emphysema (PIE) refers to a collection of air and gases outside the alveoli, the tiny sacs in the lungs that usually take in air. This trapped air causes pressure in the lungs ...

Scientists have created a model alveolar system that mimics the breathing action of the human lung and allows visualization of flow patterns within the alveoli. The chip they designed includes tubes ...

A CT scan of healthy lungs looks typical in size with no inflammation, allowing the diaphragm to dome. Lungs with emphysema can look overinflated, with muscle loss, making the diaphragm misshapen. The ...

Alveoli are the basic functional units of the human respiratory system, acting as tiny air sacs that exchange gases. Air inhaled through the mouth and nose flows into the lungs through the branched ...

The first randomized controlled trial to compare two different lung volume reduction procedures for people with emphysema has found that both lead to similar improvements in lung function, ...

Researchers at Weill Cornell Medicine and New York-Presbyterian in New York have discovered that injecting mice with healthy pulmonary endothelial cells (ECs)—the cells that line the walls of blood ...

CT-detected emphysema is linked to a higher risk of lung cancer, a risk that increases with emphysema severity, according to a new study. CT-detected emphysema is linked to a higher risk of lung ...

In 2021, an estimated 14 million adults in the United States reported a diagnosis of chronic obstructive pulmonary disease (COPD), chronic bronchitis, or emphysema. If you’re not sure what the ...

WASHINGTON, Sept. 6, 2022 – Alveoli are the basic functional units of the human respiratory system, acting as tiny air sacs that exchange gases. Air inhaled through the mouth and nose flows into the ...
