Dysfunctional breathing (DB) is implicated in physical and psychological health, however evaluation is hampered by lack of rigorous definition and clearly defined measures. Screening tools for DB include biochemical measures such as end-tidal CO(2), biomechanical measures such assessments of breathing pattern, breathing symptom questionnaires and tests of breathing function such as breath holding time.
This study investigates whether screening tools for dysfunctional breathing measure distinct or associated aspects of breathing functionality.
84 self-referred or practitioner-referred individuals with concerns about their breathing were assessed using screening tools proposed to identify DB. Correlations between these measures were determined.
Significant correlations where found within categories of measures however correlations between variables in different categories were generally not significant. No measures were found to correlate with carbon dioxide levels.
DB cannot be simply defined. For practical purposes DB is probably best characterised as a multi-dimensional construct with at least 3 dimensions, biochemical, biomechanical and breathing related symptoms. Comprehensive evaluation of breathing dysfunction should include measures of breathing symptoms, breathing pattern, resting CO(2) and also include functional measures such a breath holding time and response of breathing to physical and psychological challenges including stress testing with CO(2) monitoring.
功能失调性呼吸（DB）与身心健康有关，然而，由于缺乏严格的定义和明确的测量方法，评估受到阻碍。DB的筛查工具包括生化指标，如呼气末二氧化碳（CO₂），生物力学指标，如呼吸模式评估，呼吸症状问卷，以及呼吸功能测试，如屏气时间。
本研究调查功能失调性呼吸的筛查工具是否能测量呼吸功能的不同方面或相关方面。
使用提议用于识别DB的筛查工具，对84名自我转诊或由从业者转诊的、对自己呼吸状况表示担忧的个体进行评估。确定这些测量指标之间的相关性。
在各测量类别中发现了显著的相关性，然而不同类别变量之间的相关性通常不显著。未发现任何测量指标与二氧化碳水平相关。
DB不能简单定义。从实际应用角度来看，DB可能最好被描述为一个至少具有三个维度的多维度结构，即生化维度、生物力学维度和与呼吸相关的症状维度。对呼吸功能障碍的综合评估应包括呼吸症状测量、呼吸模式测量、静息时的CO₂测量，还应包括功能测量，如屏气时间，以及呼吸对身体和心理挑战（包括通过CO₂监测进行压力测试）的反应。
