Lifesaving microbubbles

(Wiley) Severe oxygen deficiency eventually leads to cardiac arrest. If the blood's oxygen content cannot be rapidly re-established, the patient may die within minutes. In the journal Angewandte Chemie, American scientists have introduced air-filled microbubbles that could be used as an intravenous oxygen carrier to increase the survival rate of such patients. Because they rapidly dissolve in blood, the risk of embolism is minimal.
