Evolution of bubbles from gas micronuclei formed on the luminal aspect of ovine large blood vessels

Highlights • Nanobubbles formed on hydrophobic flat surface can be the gas micronuclei that on decompression evolve as bubbles. • Large arterial and venous blood vessels from sheep were exposed to 1013 kPa for 18 h and photographed thereafter. • Hydrophobicity was shown in all blood vessels. • All o...

Description
Summary:Highlights • Nanobubbles formed on hydrophobic flat surface can be the gas micronuclei that on decompression evolve as bubbles. • Large arterial and venous blood vessels from sheep were exposed to 1013 kPa for 18 h and photographed thereafter. • Hydrophobicity was shown in all blood vessels. • All of the blood vessels produced bubbles: 18–36 bubbles/cm2. • This new mechanism may be the main source of bubble formation on decompression.
