Background The measurement of maximal respiratory pressures (MRPs) is commonly used to assess respiratory muscle strength. However, in Spain, there is no consensus on which is the most adequate measurement protocol, as theSpanish Society of Pneumology and Thoracic Surgery (SEPAR) protocol differs from the one endorsed by the American Thoracic Society/European Respiratory Society(ATS/ERS). This study compared the absolute and predictive values of maximal expiratory and inspiratory pressures (MEP and MIP) in healthy adults obtained with the two protocols. Methods A cross-sectional study with a sample of healthy adults was conducted. Lung function and MRPs were assessed. MEP and MIP were measured using a digital manometer according to the SEPAR and ATS/ERS. Protocols were applied in random order by the same trained physiotherapist. The comfort experienced with each protocol was assessed through a short questionnaire. Paired t-tests were used to compare the results from both protocols. Results A total of 31 subjects (mean age 35.7±12.4 years; 14 females; FEV=108.3±10.5%; FVC=103.7±10%) were included. There was a significant difference between MRPs favouring the SEPAR protocol, with the mean difference being 34.9±28.1 cmHO (p˂0.001) for MEP and 8±11.6 cmHO (p=0.001) for MIP. ATS/ERS protocol was, however, considered more comfortable than SEPAR (p<0.005). Conclusions This study shows that, in healthy adults, higher MRPs are obtained using the SEPAR protocol. Yet, the ATS/ERS protocol is experienced as more comfortable. Future studies are needed to analyse the application of both protocols in other populations and their associated comfort.
背景 最大呼吸压力（MRPs）的测量常用于评估呼吸肌力量。然而，在西班牙，对于哪种测量方案最为合适尚无共识，因为西班牙胸科和呼吸外科学会（SEPAR）的方案与美国胸科学会/欧洲呼吸学会（ATS/ERS）认可的方案不同。本研究比较了采用这两种方案在健康成年人中获得的最大呼气和吸气压力（MEP和MIP）的绝对值及预测值。方法 对健康成年人样本进行横断面研究。评估肺功能和MRPs。根据SEPAR和ATS/ERS方案，使用数字压力计测量MEP和MIP。由同一名经过培训的物理治疗师以随机顺序应用这两种方案。通过一份简短问卷评估每种方案带来的舒适度。采用配对t检验比较两种方案的结果。结果 共纳入31名受试者（平均年龄35.7±12.4岁；14名女性；FEV=108.3±10.5%；FVC=103.7±10%）。MRPs在支持SEPAR方案方面存在显著差异，MEP的平均差异为34.9±28.1 cmH₂O（p˂0.001），MIP的平均差异为8±11.6 cmH₂O（p=0.001）。然而，ATS/ERS方案被认为比SEPAR方案更舒适（p<0.005）。结论 本研究表明，在健康成年人中，采用SEPAR方案可获得更高的MRPs。然而，ATS/ERS方案让人感觉更舒适。未来需要开展研究分析这两种方案在其他人群中的应用情况及其相关舒适度。
