A computer-aided procedure is presented providing subjects with analogous visual feedback of respiratory resistance, which is continuously measured using the forced oscillation method. Simultaneous pneumotachographical control of the breathing volume curve makes it possible to prevent reinforcement for decreases of respiratory resistance which are due to increases of functional residual capacity (FRC). Lung hyperinflation is an unsuitable way to reduce respiratory resistance; if it occurs, feedback is interrupted until the subject decreases his FRC to its initial level. Analysis of the data of 15 adult asthmatic subjects which underwent a 12-sessions feedback training showed that no substantial changes of FRC appeared within feedback trials. Advantages of this new biofeedback technique compared to other procedures are discussed with regard to volume control and feedback signal.
本文介绍了一种计算机辅助程序，该程序为受试者提供呼吸阻力的类似视觉反馈，呼吸阻力通过强迫振荡法持续测量。对呼吸量曲线进行同步呼吸流速描记控制，能够防止因功能残气量（FRC）增加导致呼吸阻力降低而产生的强化作用。肺过度充气是降低呼吸阻力的不合适方式；如果发生这种情况，反馈将中断，直到受试者将其FRC降至初始水平。对15名成年哮喘患者进行为期12节反馈训练的数据分析表明，在反馈试验期间FRC没有出现实质性变化。就容量控制和反馈信号而言，讨论了这种新的生物反馈技术与其他程序相比的优势。
