To determine reference values for maximum static respiratory pressures in healthy children from a Brazilian region, following recommendations of the European Respiratory Society (ERS) and the Brazilian Society of Pneumology and Tisiology (SBPT).
A cross-sectional observational study was conducted with healthy children (6 to 11 years) of both sexes. The maximum inspiratory and expiratory pressures (PImax and PEmax, respectively) were measured using a digital manometer. Each child performed a minimum of three and a maximum of five maneuvers; three acceptable and reproducible maneuvers were considered for analysis. Minimum time for each maneuver was 1.5 seconds, with a one-second plateau, and one minute of rest between them. A stepwise multiple linear regression analysis was conducted for PImax and PEmax, considering correlations between independent variables: age, weight, and sex.
We included 121 children (62 girls [51%]). Boys reached higher values for maximum respiratory pressures than girls. Respiratory pressures increased with age showing moderate effect sizes (PImax: f = 0.36; PEmax: f = 0.30) between the stratified age groups (6-7, 8-9, and 10-11 years). Age and sex were included in the PImax equation (PImax = 24.630 + 7.044 x age (years) + 13.161 x sex; R2 = 0.189). PEmax equations were built considering age for girls and weight for boys [PEmax (girls) = 55.623 + 4.698 x age (years) and PEmax (boys) = 82.617 + 0.612 x weight (kg); R2 = 0.068].
This study determined new reference equations for maximal respiratory pressures in healthy Brazilian children, following ERS and SBPT recommendations.
根据欧洲呼吸学会（ERS）和巴西胸科学会（SBPT）的建议，确定巴西某地区健康儿童最大静态呼吸压力的参考值。
本研究为一项横断面观察性研究，纳入了来自巴西某地区的健康儿童（6 至 11 岁，男女不限）。使用数字压力计测量最大吸气和呼气压力（PImax 和 PEmax）。每位儿童至少进行 3 次，最多进行 5 次动作；分析时取 3 次可接受且可重复的动作。每个动作的最小时间为 1.5 秒，平台持续 1 秒，动作之间休息 1 分钟。对 PImax 和 PEmax 进行逐步多元线性回归分析，考虑了自变量（年龄、体重和性别）之间的相关性。
共纳入 121 名儿童（62 名女孩[51%]）。男孩的最大呼吸压力值高于女孩。呼吸压力随年龄增长而增加，在分层年龄组（6-7 岁、8-9 岁和 10-11 岁）之间呈中等效应大小（PImax：f = 0.36；PEmax：f = 0.30）。PImax 方程中纳入了年龄和性别（PImax = 24.630 + 7.044 x 年龄（岁）+ 13.161 x 性别；R2 = 0.189）。PEmax 方程考虑了女孩的年龄和男孩的体重：PEmax（女孩）= 55.623 + 4.698 x 年龄（岁），PEmax（男孩）= 82.617 + 0.612 x 体重（kg）；R2 = 0.068）。
本研究按照 ERS 和 SBPT 的建议，为巴西健康儿童的最大呼吸压力制定了新的参考方程。
