Pressure–volume curve between balloon filling volume and Pes at the end of expiration and inspiration, respectively. Permitted to reprint from [6]. The intermediate linear section was graphically detected and analyzed for its lower and upper limits (Vmin and Vmax). Within the appropriate filling range, we identified Vbest, i.e., the filling volume associated with the maximum difference between ΔPes
