Short-term high-frequency nasal ventilation (HFNV) of preterm neonates provides acceptable gas exchange compared to endotracheal intubation and intermittent mandatory ventilation (IMV). Whether ...

Infant mortality caused by respiratory distress syndrome in the United States decreased from ∼268 in 100,000 live births in 1971 to 98 in 100,000 live births in 1985 (1) and 17 in 100,000 live births ...

We explore the physical and structural challenges that face gas exchange surfaces in vertebrates and insects, by focusing on the role of the surfactant system. Pulmonary surfactant is a complex ...

Gas exchange occurs in the alveoli which are found in the lungs. Many spongy mesophyll cells are in contact with the air spaces, providing a large surface area for gas exchange to happen. The spongy ...

The morphometrics of the respiratory system, voluntary emersion behaviour, and gas exchange during immersion and emersion were examined in the amphibious, intertidal crab Hemigrapsus nudus. The area ...

We need to get oxygen from the air into the blood, and we need to remove waste carbon dioxide from the blood into the air. Moving gases like this is called gas exchange. As the blood moves through the ...

The respiratory system is responsible for the exchange of carbon dioxide and oxygen in the human body. This system also helps remove metabolic waste products and keep pH levels in check. The major ...

Respiratory diseases are a broad category of ailments that affect the lungs and other parts of the respiratory system. These diseases range from mild conditions like the common cold to severe and ...
