Figure 1. Viscosity of Infasurf in the absence and presence of polymers.
Viscosity of Infasurf alone (black circles) or with dextran 5% (open circles), PEG 5% (squares) or 0.25% HA (triangles) versus phospholipid concentration, determined at 23°C (left panel) or 37°C (right panel). Lines are visual guides.
