This study was conducted to explore the influence of speaking on ventilation. Twenty healthy young men were studied during periods of quiet breathing and prolonged speaking using noninvasive methods to measure chest wall surface motions and expired gas composition. Results indicated that all subjects ventilated more during speaking than during quiet breathing, usually by augmenting both tidal volume and breathing frequency. Ventilation did not change across repeated speaking trials. Quiet breathing was altered from its usual behavior following speaking, often for several minutes. Speaking-related increases in ventilation were found to be strongly correlated with lung volume expenditures per syllable. These findings have clinical implications for the respiratory care practitioner and the speech-language pathologist.
本研究旨在探讨说话对通气的影响。使用非侵入性方法测量胸壁表面运动和呼出气体成分，对20名健康青年男性在安静呼吸和长时间说话期间进行了研究。结果表明，所有受试者在说话时的通气量均高于安静呼吸时，通常是通过增加潮气量和呼吸频率来实现的。重复说话试验期间通气量没有变化。说话后安静呼吸会偏离其通常的模式，这种情况通常会持续几分钟。发现与说话相关的通气增加与每个音节的肺容积消耗密切相关。这些发现对呼吸治疗师和言语病理学家具有临床意义。
