The Maximum negative pressure (Pmax) of the PA was measured at inspiration using CFD, based on a three-dimensional PA model. Intersite differences were determined using analysis of variance and the Friedman test with Bonferroni correction. The relationship between APD and Pmax was evaluated by Spearman correlation coefficients and non-linear regression analysis.\nResults: The smallest PA site was the RA. Pmax was significantly correlated with the APD of the RA (rs = .628, P < .001). The relationship between Pmax and the APD-RA was fitted to a curve, which showed an inversely proportional relationship of Pmax to the square of the APD-RA. Pmax substantially increased even with a slight reduction of the APD-RA. In particular, when the APD-RA was 7 mm or less, Pmax increased greatly, suggesting that PA obstruction was more likely to occur.\nConclusions: The results of this study suggest that APD-RA is a useful predictor of good PA ventilation after surgery.\n\nThis is the peer reviewed version of the following article:\nYoshito Shirazawa, Tomonori Iwasaki, Kazuhiro Ooi, Yutaka Kobayashi, Ayaka
