摘要
本研究旨在探讨15例正常人双相胸甲通气时吸气负压对潮气量的影响及压力水平与潮气量的关系。我们测量了吸气负压为-5、-10、-20和-30 cm H2O时的潮气量。吸气负压-30 cm H2O是增加潮气量的必要条件。我们得出的结论是，-30 cm水的双相口罩通气显著增加了正常受试者的潮气量。
[Relationship between intermittent negative pressure level and tidal volume during biphasic cuirass ventilation in normal subjects].
The aim of this study was to investigate the effects of inspiratory negative pressure by biphasic cuirass ventilation on tidal volume and the relationship between pressure level and tidal volume in 15 normal subjects. We measured tidal volume during inspiratory negative pressures of -5, -10, -20 and -30 cm H2O. An inspiratory negative pressure of -30 cm H2O was necessary to increase tidal volume. We conclude that -30 cm H2O of biphasic cuirass ventilation significantly increases tidal volume in normal subjects.
