救急法 means first aid or first-aid methods/procedures.

The combination では is で + は:

• で marks the context / field / setting
• は marks that whole phrase as the topic

So 救急法では means something like:

• in first aid
• when it comes to first aid
• in first-aid training

It sets the scene for what follows. The sentence is saying that in the area of first aid, these are the things that get practiced.

Here are the common readings:

• 救急法 → きゅうきゅうほう
• 止血 → しけつ
• 気道異物除去 → きどういぶつじょきょ
• 担架搬送 → たんかはんそう
• 練習する → れんしゅうする

A lot of these are technical or formal compounds, so they use on-yomi readings.

Because the three nouns form a single list, and Japanese often puts を only once, after the whole list.

So:

• 止血
• 気道異物除去
• 担架搬送

are all objects of 練習する.

This is very normal in Japanese. It works like:

• A, B, C を練習する
• practice A, B, and C

You do not need to repeat を after each item.

The commas show a simple list of items. This style is common in written Japanese, especially in textbooks, instructions, schedules, and formal descriptions.

So:

• 止血、気道異物除去、担架搬送を練習する

is a straightforward written list.

If you used と, it would also be understandable:

• 止血と気道異物除去と担架搬送を練習する

But that sounds a bit heavier and less natural in this kind of formal listing. Commas are more concise.

止血 literally means stopping bleeding.

• 止 = stop
• 血 = blood

In a first-aid context, it means hemostasis or bleeding control.

So this is not just a random vocabulary item; it is a technical first-aid skill.

It is a compound noun made of smaller parts:

• 気道 = airway
• 異物 = foreign object / foreign body
• 除去 = removal

So the whole thing means:

• airway foreign-body removal
• more naturally in English, removing a foreign object from the airway
• in practical first-aid terms, clearing an airway obstruction

Japanese often packs technical ideas into long noun compounds like this.

Good question. 気道異物除去 is a compact compound noun, which is very common in formal Japanese.

A more expanded version could be:

• 気道の異物の除去

That is grammatically clear, but it sounds more explanatory and less like a technical label.

The version in the sentence, 気道異物除去, is the kind of compact wording often used in:

• medical language
• manuals
• headings
• training materials

So both are understandable, but the compound form sounds more formal and specialized.

Yes, here 担架搬送 is functioning as one compound noun.

It is made of:

• 担架 = stretcher
• 搬送 = transport / conveyance

Together it means:

• stretcher transport
• transporting a person by stretcher

Japanese often combines nouns like this in technical or institutional language.

A more expanded version might be something like:

• 担架で搬送すること
• 担架による搬送

But 担架搬送 is shorter and sounds like the name of a training item or procedure.

練習する means to practice. That fits well because these are practical skills.

Compare:

• 練習する = practice
• 学ぶ = learn/study
• する = do

In first-aid training, the idea is not just learning the theory, but practicing the procedures. So 練習する is the most natural choice.

Also, 練習 is a noun, and adding する makes it into a verb:

• 練習する = to practice

You may also see 練習をする, which means the same thing. The shorter 練習する is very common.

The subject is omitted, which is very common in Japanese.

Depending on context, it could mean:

• we practice ...
• students practice ...
• trainees practice ...
• one practices ...

Japanese often leaves out the subject when it is obvious from the situation.

So the sentence is probably describing a class, course, or training program, where the subject is understood from context.

It is natural, but it sounds formal and instructional, not casual everyday conversation.

Reasons:

• it uses technical terms like 止血, 気道異物除去, and 担架搬送
• it uses a compact written list with commas
• it has the straightforward explanatory structure Xでは、Yを練習する

This is the kind of Japanese you might see in:

• a textbook
• a training manual
• a course description
• a safety or medical instruction sheet

In casual speech, someone might use simpler expressions instead of these technical compounds.
