I will give you one of my secrets.
2
That is how to make a successful radial artery puncture.
3
That's very important and difficult,
4
but today you can learn everything.
5
Creating an environment that can relax the patient is the most important.
6
Avoiding excitement of the sympathetic nerves reduces somewhat the risk of vasoconstriction.
7
The puncture location should be 10-15 mm from the styloid process on the palmer side of the upper arm,
8
where the pulse can be most easily acquired.
9
Concentrate and use two or three fingers to search for the point where the pulse is strongest.
10
If the pulse becomes weaker,
11
you can wait for it to return or you can use the left wrist.
12
With the double wall puncture method,
13
hold the plastic cannula needle at a 45 degree angle or slightly higher.
14
There are times when the plastic cannula needle puncture is successful,
15
but it is not possible to insert the guide wire.
16
However, with the double wall puncture method,
17
because the end of the cannula needle is securely within the vascular lumen,
18
the risk of a guide wire insertion failure is lower failure is lower.
19
After insertion, drop the plastic cannula to a low angle
20
and facilitate guide wire insertion in order to minimize the risk of the guide wire damaging the artery.
21
By securely immobilizing the left wrist,
22
it is possible to slowly pull out the plastic cannula.
23
Sufficiently moistening the sheath will allow it to be inserted smoothly.
24
Further reduce the sheath insertion angle and slowly insert it along the path of the artery.
25
A sheath that has a hydrophilic coating can be smoothly inserted and removed.
26
Looking at the series of steps,
27
one technique for ensuring a safe procedure is the following.
28
Although the angle is rather high during the plastic cannula needle puncture,
29
the angle is then gradually lowered,
30
and when the sheath is inserted,
31
it is parallel to the path of the artery.
32
I missed my puncture.
33
Even if you fail, do not pull out the needle.
34
The first puncture is the best puncture.
35
Without pulling out the needle,
36
change the angle and puncture again.
37
It is possible that this may also fail.
38
In this case, change to the reverse direction and puncture again without removing the needle.

什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
