Plateau pressure, compliance, and resistance data for the pressure support ventilation (PSV) patient group. PSV patient group - regression and corresponding Bland-Altman plots for inspiratory plateau pressure (Pplt) (A), respiratory system compliance (Crs) (B), and total respiratory resistance (Rtot) (C) are shown comparing the end inspiratory pause (EIP) and expiratory time constant (ƬE) methods. Pplt bias = 0.94; Pplt precision = -0.38 to 2.26; Pplt limits of agreement = -1.70 to 3.58. Crs bias = -0.002; Crs precision = -0.006 to 0.002; Crs limits of agreement = -0.011 to 0.006. Rtot bias = 0.57; Rtot precision = -0.39 to 1.53; Rtot limits of agreement = -1.35 to 2.49.
