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

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 ...

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 ...

Aerobic respiration needs oxygen, and it produces carbon dioxide as a waste product. The human respiratory system contains the organs that allow us to get the oxygen we need and to remove the waste ...

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 ...

Flaring of natural gas from oil wells appeared to cause an increase of around 11,000 hospital visits for respiratory reasons in North Dakota, US, up to 60 miles away from oil drilling sites. Flaring ...
