Ventilation with perfluorocarbon fluid improves lung function in conditions involving surfactant deficiency and dysfunction, including respiratory distress syndrome and adult respiratory distress syndrome.
(Perflubron, NCI Thesaurus)
No, Mr. Malone, I will place no restriction upon your correspondence, since the ventilation of the facts is the object of your journey; but I demand that you shall give no particulars as to your exact destination, and that nothing be actually published until your return.

(Cardiac Compression during Initial Resuscitation, NCI Thesaurus)
An individual trained and certified to provide all basic and intermediate life support measures in addition to using invasive medical procedures (including intravenous therapy, cardiac defibrillation, administering medications and solutions, and using ventilation devices) as dictated by state law and performed under medical control in case of medical emergencies, hazardous materials exposure, child birth, abuse, fires, flood, accidents, trauma, and psychiatric crises.
(Paramedic, NCI Thesaurus)
There are two main types of natural cross-ventilation: wind-driven and buoyancy-driven.
(Wind more effective than cold air at cooling rooms naturally, University of Cambridge)
Used as a contrast agent for magnetic resonance imaging (MRI), perflubron is also used as a liquid ventilation agent to improve pulmonary gas exchange and lung compliance and may be used in surgery to reduce or eliminate the need for donor blood.
(Perflubron, NCI Thesaurus)
Cross-ventilation occurs in rooms that have windows on opposite sides of a room.
(Wind more effective than cold air at cooling rooms naturally, University of Cambridge)
In contrast, wind can increase ventilation rates by as much as 40% above that which is driven by a temperature difference between a room and the outdoors.
(Wind more effective than cold air at cooling rooms naturally, University of Cambridge)
Ventilation can also be driven by temperature differences between the inside and outside of a room, as incoming air is heated by people or equipment, resulting in a buoyancy-driven flow at a window.
