Octafluoropropane

[3] In medicine, octafluoropropane may compose the gas cores of microbubble contrast agents used in contrast-enhanced ultrasound.

Octafluoropropane microbubbles reflect sound waves well and are used to improve the ultrasound signal backscatter.

It is used in eye surgery, such as pars plana vitrectomy procedures where a retina hole or tear is repaired.

The gas provides a long-term tamponade, or plug, of a retinal hole or tear and allows re-attachment of the retina to occur over the several days following the procedure.

[4] It is the active liquid in PICO-2L dark matter bubble detector (joined PICASSO and COUPP collaborations).

NFPA 704 four-colored diamond Health 1: Exposure would cause irritation but only minor residual injury. E.g. turpentine Flammability 0: Will not burn. E.g. water Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazard SA: Simple asphyxiant gas. E.g. nitrogen, helium
