Abstract: Compressible and concentrated suspensions containing gas-filled microbubbles, uses thereof for delivering gas into a subject in need thereof, and systems for delivering the compressible suspensions. The gas-filled microbubbles each comprise a gas core surrounded by a lipid membrane, which includes (a) one or more lipids, such as 1,2-disteroyl-sn-glycero-3-phosphocholine (DSPC) or dipalmitoylphosphatidylcholine (DPPC), and (b) one or more stabilizing detergents, such as poloxamer 188, Pluronic F108, Pluronic F127, polyoxyethylene (100) stearyl ether, cholesterol, gelatin, polyvinylpyrrolidone (PVP), and sodium deoxycholate (NaDoc).

Abstract: Compositions containing a carrier and microbubbles encapsulating one or more gases, preferably oxygen, and methods for making and using the compositions are described herein. The microbubbles contain a lipid envelope. The compositions may be administered to a patient to quickly deliver large amounts of oxygen to the patient's blood supply or directly to a tissue in need of oxygen. The compositions may be administered via injection or as a continuous infusion. The compositions contain a concentrated microbubble suspension, where the suspension contains at least 40 mL oxygen/dL suspension. The microbubbles are preferably less than 20 microns in diameter, more preferably less than 15 microns in diameter. The microbubbles described herein may be administered to a patient in an effective amount to increase in oxygen concentration in the patient's blood, and/or one or more tissues or organs.

Abstract: Compositions containing a carrier and microbubles encapsulating one or more gases, preferably oxygen, and methods for making and using the compositions are described herein. The microbubbles contain a lipid envelope formed of at least one base lipid and at least one emulsifying agent. The compositions may be administered to a patient to quickly deliver large amounts of oxygen to the patient's blood supply or directly to a tissue in need of oxygen. The compositions may be administered via injection or as a continuous infusion.
