Table 2. Static Mechanics of the Velopharynx and the Oropharynx in Supine and Lateral Positions
Values are medians (10–90 percentiles). Quality of the fit is provided by coefficient r2.
*P < 0.05 compared with supine.
A = Amax− B * exp(−K * Paw), where A and Pawdenote cross-sectional area of the pharyngeal airway and airway pressure; Amax= maximum cross-sectional area; B and K = constants obtained by fitting the pressure–area relationship of each pharyngeal airway to an exponential function; P′close= estimated closing pressure calculated by ln(B/Amax)K−1.
