The Development and The Clinical Application of The Total Respiratory Center Function Test

我们研制了一种新型的脑干呼吸功能自动测定仪。该仪器由两个压力计和一个记录器组成。该压力计由两个压力计组成，用于测量呼吸道闭塞压力和口腔空气流量。该仪器的原理是由于呼吸中心的吸气相是由迷走神经激活的。我们知道，呼吸中心已经根据胸壁内压的变化来控制呼吸，从而移动肺部。利用这台新仪器，我们可以分析全吸气期的气道闭塞压力，P&lt；@D20.1@&gt；D2(0.1秒时的气道闭塞压)和呼吸曲线。因此，我们不仅可以分析P&lt；@D20.1@&Gt；D2，而且还可以分析某些呼吸系统疾病患者吸气和呼气之间的转换机制。特别是，我们可以得到一个有趣的结果P&lt；@D20.1@Gt；D2；非附着性哮喘患者(28.0()Sy.+-)。[)7.5 mm H&lt；@D22@&>D2O)大于正常人的P&lt；@D20.1@&>D2(17.6()SY+-。[)4.7 mm H&lt；@D22@&>D2O)。虽然我们必须研究非附着性哮喘患者P&lt；@D20.1@&Gt；D2升高的机制，但我们相信这台机器对呼吸系统疾病患者是有用的。

We developed the new automatic machine to measure the respiratory functions which is in brain stem.This machine is composed two manometers to measure the airway occlusion pressure and the air flow of mouth included computer tips and one recorder.The principle of this machine is due to the inspiratory phase of breath is activated by N.Vagus from the respiratory center.We know already the respiratory center controls the breath based on the change of inter pressure of chest wall which can moves the lungs.By using of this new machine, we could analyze airway occlusion pressure duaring full inspiratory phase, P<@D20.1@>D2 (airway occlusion pressure at 0.1 secounds) and breath curves. So, we could analyze not only P<@D20.1@>D2 but the switch mechanism between inhale and exhale of breath among patients with some respiratory diseases. Specially, we could have an interesting result P<@D20.1@>D2 of non-attached bronchial asthma cases (28.0(]SY.+-。[)7.5mmH<@D22@>D2o) is more than P<@D20.1@>D2 of normal cases (17.6(]SY.+-。[)4.7mmH<@D22@>D2o). Although we must study the mechanisms of increasing of P<@D20.1@>D2 of non-attached bronchial asthma cases, we believe this machine is useful for patients with respiratory diseases.
