syoubyousya no zyoutai wo kakuninsuru.

It is read:

しょうびょうしゃ の じょうたい を かくにんする。

Word readings:

• 傷病者 = しょうびょうしゃ
• 状態 = じょうたい
• 確認する = かくにんする

In normal writing, it would usually appear without spaces:

傷病者の状態を確認する。

傷病者 is a formal word meaning an injured or sick person.

It is made up of:

• 傷 = injury, wound
• 病 = illness
• 者 = person

So it refers to someone who is injured, ill, or both. It is especially common in medical, emergency, rescue, or disaster-response contexts.

の links two nouns together.

Here, 傷病者の状態 means:

• the condition of the injured/sick person
• or more naturally, the casualty’s condition

So の is working a lot like ’s or of in English.

Examples:

• 先生の本 = the teacher’s book
• 日本の文化 = the culture of Japan
• 傷病者の状態 = the condition of the casualty

を marks the direct object of the verb.

The verb here is 確認する = to check / confirm.

So the thing being checked is 状態.

Structure:

• 状態を確認する = check the condition

In other words:

• 状態 = condition
• を = marks it as the thing affected by the verb
• 確認する = check/confirm

Not exactly. 確認する means to confirm, to check, or to verify.

It sounds more deliberate and careful than just 見る (to look at / see).

So:

• 見る = simply look
• 確認する = check and make sure

In this sentence, 確認する suggests assessing the person’s condition carefully, not just glancing at them.

確認する is the plain/dictionary form of the verb.

In Japanese, this form is often used in:

• manuals
• procedures
• instructions
• labels
• training materials
• bullet-point steps

So this sentence sounds like a procedural instruction such as:

• Check the casualty’s condition.

If you wanted a polite full sentence, you might say:

• 傷病者の状態を確認します。

If you wanted to tell someone directly to do it:

• 傷病者の状態を確認してください。

Yes, the subject is omitted, which is very normal in Japanese.

Japanese often leaves out information that is obvious from context. In a training manual or emergency procedure, the implied subject might be:

• you
• the responder
• the medic
• one

So the sentence does not need to say you explicitly.

A natural English interpretation would be:

• Check the casualty’s condition.

It can function as a complete sentence, but in context it very often feels like an instruction or procedural step.

That is because:

• the subject is omitted
• the verb is in dictionary form
• the wording is concise and formal

So in a first-aid manual, it would likely be understood as a step such as:

• Check the casualty’s condition.

It could also appear as a task label or checklist item.

A very literal breakdown is:

• 傷病者 = injured/sick person
• の = ’s / of
• 状態 = condition, state
• を = object marker
• 確認する = confirm, check

So literally:

Confirm the condition of the injured/sick person.

More natural English:

• Check the casualty’s condition.
• Assess the injured person’s condition.

No. Standard Japanese normally does not use spaces between words.

So this:

傷病者　の　状態　を　確認する。

would normally be written as:

傷病者の状態を確認する。

Spaces are often added in beginner materials to make the structure easier to see.

Yes. Japanese nouns usually do not mark singular vs. plural the way English does.

So 傷病者 can mean:

• an injured/sick person
• injured/sick people

The exact meaning depends on context.

In this sentence, it will often be understood as singular or generic:

• Check the casualty’s condition or
• Check the condition of the casualty/patient

It sounds fairly formal and professional.

Reasons:

• 傷病者 is a technical/formal term
• 状態 is neutral and formal
• 確認する is a common formal verb in instructions and procedures

This is not the kind of phrase you would usually use in casual everyday conversation unless you were talking in a medical, rescue, or training context.
