气道的横截面积可以从它们对在气道开口处引入的声压脉冲的响应来估计。如果气道在这些频率下表现不严格，则预计这些面积估计值会出现误差。在八只狗，我们测试了这种技术的准确性，以估计气管横截面积进行比较，从放射性支气管造影面积估计。使用该技术的气管面积与X线片确定的面积无统计学差异。结果表明，狗的气管确实表现出足够的刚性，因此这种方法可以用来测量其横截面积。
The cross-sectional area of airways can be estimated from their response to an acoustic pressure pulse introduced at the airway opening. Errors in these area estimates are expected if the airways do not behave rigidly at these frequencies. In eight dogs we tested the accuracy of this technique to estimate tracheal cross-sectional areas by comparing them with area estimates made from radiographic bronchograms. Tracheal areas using this technique were not statistically different from areas determined radiographically. The results indicate that the dog trachea does behave rigidly enough so that this method can be used to measure its cross-sectional area.
