The effect of bulk fluid gas saturation, surface tension, and viscosity on the mean (n = 5) ADV and IC thresholds. All fluids were heated to 37°C and contained albumin-coated, PFP droplets at a concentration of 9×104 droplets per mL. The IC threshold of gas-saturated water without droplets, tested under the same conditions, was 5.6±0.2 MPa while no IC was observed for degassed water without droplets.
