测量指标:

Outcomes:

指标中文名:

膈肌收缩速度

指标类型:

主要指标

Outcome:

Diaphragm contraction velocity

Type:

Primary indicator

测量时间点:

麻醉诱导前、拔管后即刻、拔管后30min。

测量方法:

从吸气最低点到吸气最高点的所用时间即为膈肌峰值吸气振幅时间,膈肌移动度与的膈肌峰值吸气振幅时间比值即为膈肌收缩速度。

Measure time point of outcome:

Before anesthesia induction, immediately after extubation, and 30 minutes after extubation.

Measure method:

The time taken from the lowest point of inhalation to the highest point of inhalation is the peak inhalation amplitude time of the diaphragm, and the ratio of the diaphragm mobility to the peak inhalation amplitude time of the diaphragm is the diaphragm contraction speed.

指标中文名:

膈肌移动度

指标类型:

主要指标

Outcome:

Diaphragmatic mobility

Type:

Primary indicator

测量时间点:

麻醉诱导前、拔管后即刻、拔管后30min。

测量方法:

患者取平卧位,平静呼吸,将低频凸阵探头放于右侧腋前线与腋中线的肋弓下缘,通过旋转超声探头,使超声束以尽可能接近 90°的角度到达膈肌穹窿最高点,通过图像的聚焦增益,找到一条紧贴肝脏且随呼吸运动而移动的高亮回声图像即为膈肌。然后将超声检查机切换到运动模式(M模式),图像表现为一条随呼吸运动而改变的正弦波。M模式下水平轴代表时间,每一小格的时间为0.5 s, 纵轴代表位移,每一小格的距离为2 cm。吸

Measure time point of outcome:

Before anesthesia induction, immediately after extubation, and 30 minutes after extubation.

Measure method:

The patient is placed in a supine position, breathing calmly. The low-frequency convex array probe is placed under the lower edge of the rib arch along the right anterior axillary line and mid-axillary line. By rotating the ultrasound probe, the ultrasound beam is directed as close to a 90° angle as possible to reach the highest point of the diaphragmatic dome. Using the image's focusing gain, a bright echo image that closely adheres to the liver and moves with respiration is identified as the d

指标中文名:

膈肌浅快呼吸指数

指标类型:

主要指标

Outcome:

Diaphragmatic rapid shallow breathing index

Type:

Primary indicator

测量时间点:

麻醉诱导前、拔管后即刻、拔管后30min。

测量方法:

从一个吸气点到下一个相邻的吸气点的时间为膈肌做一个呼吸周期所用时间,可计算出呼吸频率(respiratory rate, RR),RR与膈肌移动度的比值即为膈肌浅快呼吸指数

Measure time point of outcome:

Before anesthesia induction, immediately after extubation, and 30 minutes after extubation.

Measure method:

The time from one inhalation point to the next adjacent inhalation point is the time it takes for the diaphragm to complete one respiratory cycle. The respiratory rate (RR) can be calculated, and the ratio of RR to the mobility of the diaphragm is the diaphragm shallow and rapid respiratory index
