Objective To determine if pressure support ventilation (PSV) weaning from general
anesthesia affects ventilation or oxygenation in horses. Study design Prospective
randomized clinical study. Animals Twenty client‐owned healthy horses aged 5±2 years,
weighing 456±90 kg. Methods In the control group (CG; n= 10) weaning was performed by a
gradual decrease in respiratory rate (f R) and in the PSV group (PSVG; n= 10) by a gradual
decrease in f R with PSV. The effect of weaning was considered suboptimal if PaCO 2> 50 …
