쉐도잉 연습: How to Avoid Common Mistakes During Insertion in Colonoscopy (Using the Olympus CM-15 Colon Phantom) - 영상으로 영어 말하기 배우기

Forbidden movements Let's move on to forbidden movements.

One common problem in colonoscopy is the air issue.

The air button is easily available,

So it's quite easy to get into it and just hold the fingertip on it.

And you want to have a good view of the lumen, so you just blow air so you can continue.

And you want to have an almost clear view of the colon.

But by doing this, you get into trouble.

So you have a very nice view so that you can continue.

But look at the sigmoid colon.

Even if I try hard, I cannot pull it down.

It's impossible because of the air and this confined cage which is the abdomen.

So the only way to continue is to decrease the air

if you get into this situation so that you can really reduce this.

So please take care of the air button.

Typical mistake seen with right and left movements using the shaft of the endoscope.

Okay, this right and left shaft movement that people think that work,

as you can see, does not do anything inside the colon.

So this is movement that should be forbidden.

Twisting your wrist at the control body is crucial for a rotational effect at the tip of the endoscope.

Improper way to control angulation.

Okay, another forbidden movement.

Don't use your right hand to do the right and left angling.

To manipulate the endoscope, you want to use up and down angulation with the joint of your thumb.

Up, down, and with the tip of your thumb,

left, right, and now you can combine these movements, like this.

Improper way of reducing a loop.

A common problem in colonoscopy is to get a loop outside the colon at the shaft of the instrument.

The common recommendation is that you send that loop to the umbilicus.

But by doing that, sending it, you shorten the umbilicus and you reduce the mobility of the instrument.

So movements at this level become more difficult.

So you reduce your movements.

The correct way to reduce it is by rotating the shaft of the instrument like this.

Slowly and...

And lastly, don't push the colonoscope too much.

You see...

the inside of the lumen is not moving, but you still try to push.

What is happening is you're making a huge loop inside the abdomen,

and this is very painful for the patient.

When you see this movement in the colon, you should not push further.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
