The maximum static respiratory pressures, namely the maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), reflect the strength of the respiratory muscles. These measures are simple, non-invasive, and have established diagnostic and prognostic value. This study is the first to examine the maximum respiratory pressures within the Brazilian population according to the recommendations proposed by the American Thoracic Society and European Respiratory Society (ATS/ERS) and the Brazilian Thoracic Association (SBPT).
To establish reference equations, mean values, and lower limits of normality for MIP and MEP for each age group and sex, as recommended by the ATS/ERS and SBPT.
We recruited 134 Brazilians living in Belo Horizonte, MG, Brazil, aged 20-89 years, with a normal pulmonary function test and a body mass index within the normal range. We used a digital manometer that operationalized the variable maximum average pressure (MIP/MEP). At least five tests were performed for both MIP and MEP to take into account a possible learning effect.
We evaluated 74 women and 60 men. The equations were as follows: MIP=63.27-0.55 (age)+17.96 (gender)+0.58 (weight), r(2) of 34% and MEP= - 61.41+2.29 (age) - 0.03(age(2))+33.72 (gender)+1.40 (waist), r(2) of 49%.
In clinical practice, these equations could be used to calculate the predicted values of MIP and MEP for the Brazilian population.
最大静态呼吸压力，即最大吸气压力（MIP）和最大呼气压力（MEP），反映呼吸肌的力量。这些测量方法简单、无创，且具有既定的诊断和预后价值。本研究是首次根据美国胸科学会和欧洲呼吸学会（ATS/ERS）以及巴西胸科学会（SBPT）提出的建议，对巴西人群的最大呼吸压力进行研究。
按照ATS/ERS和SBPT的建议，为各年龄组和性别建立MIP和MEP的参考方程、平均值及正常下限。
我们招募了134名居住在巴西米纳斯吉拉斯州贝洛奥里藏特市、年龄在20 - 89岁之间、肺功能测试正常且体重指数在正常范围内的巴西人。我们使用了一种数字压力计来测量最大平均压力（MIP/MEP）这一变量。为考虑可能的学习效应，对MIP和MEP均进行了至少五次测试。
我们评估了74名女性和60名男性。方程如下：MIP = 63.27 - 0.55（年龄）+ 17.96（性别）+ 0.58（体重），决定系数r²为34%；MEP = - 61.41 + 2.29（年龄）- 0.03（年龄²）+ 33.72（性别）+ 1.40（腰围），决定系数r²为49%。
在临床实践中，这些方程可用于计算巴西人群MIP和MEP的预测值。
