We present here an example of an important biomedical technique in which it is critical to understand and avoid bubbleudnucleation in supersaturated aqueous solutions of oxygen. By doing so it is possible to inject highly supersaturated oxygenudsolutions through a small capillary without the formation of significant gas bubbles. The potential medical benefits ofuda successful technique of this kind are substantial and multi-faceted. Deprivation of oxygen even for brief periods ofudtime such as occur during heart attacks or strokes results in cell damage or death - and is a primary cause of permanentudphysiological damage. Consequently rapid therapeutic oxygen delivery systems could substantially enhance the treatment,udfor example, of acute myocardial infarction or acute cerebral stroke.
