Effects of fluid load on cardiovascular function during stepwise lung recruitment manoeuvre in healthy dogs

Compared to baseline, CO decreased during the RM in both groups. However, there was a significantly higher CO during the second RM at the highest pressure step (P < 0.05) and during all decreasing pressure steps (P < 0.05). In conclusion, a previous crystalloid fluid load could reduce the impact of a RM on CO in healthy dogs.
