Fig. 2. Air embolism conformational changes during entrapment. Embolism (A ) diameter, (C ) length, and (E ) aspect ratio (bubble length/radius) at: initial lodging (Initial) and maximal deformation (Postlodging). Parameters of (B ) percent bubble constriction, (D ) percent bubble elongation, and (F ) nondimensional embolism deformation, presented as increase in aspect ratio. Animal groups are control (filled squares) and surfactant pretreatment (open squares). Statistical significance noted at P < 0.05 between groups (asterisk) and between time points within groups (diamonds).
