The measurement of respiratory resistance by forced oscillation requires minimal patient co-operation and should be a useful test in children. Sixty-eight children and adolescents with obstructive lung disease were studied using two different techniques. In patients with severe obstructive lung disease, unexpectedly low values for respiratory resistance were found when the measurement was made at points of peak flow (write-out method). Measurements made at simulated resonant frequency (subtraction method) in these patients were more in keeping with other tests of respiratory function; however, they probably did not reflect true respiratory resistance. The subtraction method of measuring respiratory resistance would seem to be of value in separating the normal from the abnormal, but the absolute values in obstructed subjects are difficult to interpret.
通过强迫振荡测量呼吸阻力所需的患者配合极少，对儿童应是一项有用的检测。使用两种不同技术对68例患有阻塞性肺病的儿童和青少年进行了研究。在患有严重阻塞性肺病的患者中，当在峰值流量点（写出法）进行测量时，发现呼吸阻力值出人意料地低。在这些患者中，在模拟共振频率下（减法法）进行的测量与其他呼吸功能检测结果更相符；然而，它们可能并未反映真正的呼吸阻力。测量呼吸阻力的减法法在区分正常与异常方面似乎有价值，但阻塞性受试者的绝对值难以解释。
