  • Experimental reports in septic models demonstrate no increase in extravascular lung water when hydrostatic pressures are maintained at low levels, indicating that in sepsis, the primary determinant of extravascular fluid flux appears to be microvascular pressure rather than colloid osmotic pressure. 65 Taken together, these data suggest that when lower filling pressures are maintained, there is no significant difference in the development of pulmonary edema with crystalloids or colloids.
