呼气

Objective To explore the significance of negative expiratory pressure technique in detecting expiratory flow limitation in chronic obstructive pulmonary disease patients.

目的 探讨呼气负压技术在不能完成常规肺功能测定的慢性阻塞性肺疾病患者中的临床应用价值。

OBJECTIVE: To establish reference values of peak expiratory flow for children in Xinjiang.

目的：建立新疆地区正常学龄期儿童最大呼气峰流速正常参考值。

Using the expiratory resistor SPV and PPV predicted fluid responsiveness with good sensitivity and specificity.

使用呼气电阻时，收缩压变异和脉压变异能够较好的预测容量反应的敏感性和特异性。

Density difference on expiratory HRCT exists in various regions of lung in healthy adults.

结论健康成人的肺呼气相HRCT上各区域间存在着密度差异。

Objective To explore influence of different positive end expiratory pressure level on ventilative efficincy of premature infant with respiratory distress syndrome.

目的 探讨不同呼气末正压水平对早产儿通气效率的影响。

Air-trapping on expiratory HRCT scan can be quantified and pulmonary function of the patient can be assessed by quantitative index.

呼气相HRCT上的空气潴留征可以定量分析，并且通过定量指标能够反映患者的肺功能状况。

The choice of appropriate intubation, management of PEEP and handling the juncture of extubation were critical.

适当插管方法的选择、低呼气末正压呼吸的管理、掌握安全的拔管时机是MO患者麻醉的关键。

Methods: deep breath when you tighten the gluteal muscle, and relax when you exhale, so repeatedly.

在你深吸气的时候，收紧臀部肌肉，当你呼气的时候放松，如此反复。

At the end of respiration or inspiration, intrapulmonary pressure equals atmospheric pressure

在呼气末或吸气末，肺内压等于大气压

Since the most significant difference happened between the middle phase of expiration and the middle phase of inspiration, this result implies that it is the intrapulmonary pressure and the cardiac volume, but not the relative position of the heart and electrodes, which cause the variation of the amplitude of QRS complex.

其中QRS波的振幅在呼气中期最高在吸气中期最低，根据呼吸运动时肺容积及肺内压变化的规律，认为是由于胸腔压力和心室舒容积的改变，而不是心脏与电极间的相对位置的改变造成了QRS波振幅的变化。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
