1
Okay, so can you tell me how is heat lost during anaesthesia and surgery?
2
Okay, so heat loss.
3
Is there a way for a diagram to explain this?
4
So you've got the patient on the operating table.
5
I'll draw that quickly.
6
Now, the main way in which heat is lost in an anaesthetic is through radiation, the infrared radiation, and that counts for 40%.
7
Then convection currents count for 30%, whereby warm air is moved away from the body,
8
aided by laminar flow and moving heat away from the body that way.
9
then a further 15% is lost through evaporation through the energy of latent heat of vaporisation.
10
Respiration accounts for approximately 10%
11
which can be broken down into 8% for latent heat of vaporisation of the gases and 2% of heating the inhaled gases.
12
There is a further small amount of heat lost through conduction through solid services such as the operating theatre
13
and through IV fluids into the patient.
14
Okay, alright let's come back to this 40% that you described of radiation.
15
Can you tell me what factors affect the amount of heat loss through radiation?
16
OK, so there's a number of factors.
17
The first which is the absolute temperature.
18
Stefan Boltzmann gives an equation where...
19
OK, don't go into detail of the equation.
20
What's the important point about that law?
21
So the emissive radiation is proportional to a power of 4, the absolute temperature.
22
So therefore the hotter the body is, the greater the temperature loss through that body is.
23
The other ways in which heat is lost through radiation, the temperature difference between the body and the surrounding areas, the exposure of the body,
24
so the exposure of the patient, then the amount of insulation the body has,
25
so if they're wearing blankets or clothing or body fat, will reduce heat loss.
26
And lastly, the amount of degree of vasodilation, so that the more vasodilated the patient is, the more blood flow there is to the skin,
27
and the greater radiated heat is lost through that.
28
OK, all right.
29
Let's think about what actually goes on during an anesthetic now.
30
So what are the phases of heat loss during anesthetic?
31
Is it all lost at the same time?
32
Or what happens?
33
OK, do I draw a graph?
34
Yeah, do.
35
So the graph for heat loss, I'll do time in hours at the bottom,
36
start at 0, and temperature in Celsius.
37
The curve essentially looks like this.
38
So in the first hour to two hours, you have rapid heat loss of one to five degrees
39
which is accounted for by redistribution of blood and between there
40
and the next five hours temperature loss decreases and after which temperature plateaus to a fairly stable level.
41
Okay thank you.
42
That was a pass for that candidate.
43
They were able to show a detailed knowledge coupled with a good understanding of the subject.
44
And were able to complement their answer by the use of diagrams and graphs and also the use of an equation.
45
Diagrams generally are not compulsory.
46
They need to add to the answer rather than just being the answer.
47
And occasionally in the exam you will be given an artefact or a diagram already in which to base your answer upon.
48
If you choose to use a diagram, it's important that you make them as large as you can, make them clear and relevant to the question you're being asked,
49
not just the diagram because you happen to remember it.
50
It's also important to use the time whilst you're drawing the diagram to help answer the question.
51
Don't draw the diagram and then answer the question.
52
The two need to be used at the same time.
53
It's also helpful if it looks like it's not the first time you've drawn the diagram.
54
Graphs too need to be along the same lines, they need to be labelled and you need to think about whereabouts your line goes on the graph.
55
Does it go through the zero point or not, where does it actually fit?
56
So in summary that was a well structured answer, able to show knowledge and understanding well and used graphs and diagrams appropriately.

이 비디오로 배울 수 있는 것
이 영상은 의학 분야의 전문 대화를 통해 복잡한 주제를 명확히 설명하는 기술을 연습할 수 있습니다. 그림이나 그래프를 사용해 내용을 보강하는 방법, 비율과 과정을 단계적으로 말하는 법을 배울 수 있어 IELTS 스피킹과 같은 시험에서도 유용한 전략을 익힐 수 있습니다. 또한, 전문 용어를 포함한 긴 문장을 자연스럽게 이어가는 회화 흐름 관리도 연습할 수 있습니다.
들어야 할 소리: 연결된 발음
영어 대화에서 자주 나타나는 연결 발음을 주목해보세요. 예를 들어 "heat loss"는 [히트로스]처럼 't'와 'l'이 연결되며, "latent heat"는 [레이턴트히트]로 발음됩니다. "a number of factors"에서 "a"는 [어]가 아니라 [에이]로 강조되지만, "of"는 [어브]가 아닌 [어프]로 축약되기도 합니다. 이러한 연결과 축약을 듣고 따라하면 유튜브 영어 공부에서 실제 회화에 더 가까운 발음을 익힐 수 있습니다.
원어민처럼 말하기: 리듬과 강세
원어민처럼 말하려면 강세와 리듬을 주의깊게 살펴야 합니다. 이 비디오에서 화자는 "40%", "30%"와 같은 숫자, "radiation", "convection"과 같은 키워드에 강세를 두어 중요한 정보를 강조합니다. 또한, "the first which is...", "the other ways in which..."와 같은 구문에서 문장의 흐름을 유지하기 위해 리듬을 조절합니다. shadowing site에서 이 대화를 따라하며 발음과 강세, 리듬을 연습하면 영어 회화 연습 효과가 더욱 커집니다. 특히, 그림을 설명할 때 사용하는 "so you've got...", "I'll draw that quickly"와 같은 표현은 자연스러운 대화를 이끌어내는 데 도움이 됩니다.
이 비디오는 전문 지식뿐만 아니라 영어로 복잡한 내용을 전달하는 기술을 함께 키울 수 있는 좋은 자료입니다. shadowspeaks와 같은 방법을 사용해 반복적으로 연습하면, 의학 분야뿐만 아니라 다양한 주제에서도 자신감 있게 이야기할 수 있게 될 것입니다.
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.
