Abstract
The genesis of bubble formation leading to decompression sickness is a problem that continues to evade many research efforts. Several models of bubble formation have been reviewed and can be summarized by the following classifications: a) de novo formation, b) critical volume concepts, and c) pre-existing gas nuclei. The latter two classifications circumvent the complex question of gas phase separation. Nevertheless, a knowledge of the parameters involved in this de novo event is required to correctly model the growth of the gas phase even if the nucleation itself appears insignificant. In this paper, we examine the conditions under which heterogeneous nucleation (which is thermodynamically favorable over homogeneous nucleation) can occur in the physiological environment.
