Questions & Answers about kokyuu no kakunin o suru.

What is the basic grammatical breakdown of 呼吸の確認をする?

A natural breakdown is:

• 呼吸 = breathing / respiration
• の = links nouns, similar to of
• 確認 = confirmation / check
• を = marks the direct object
• する = to do

So the structure is:

• 呼吸の確認 = checking/confirmation of breathing
• 呼吸の確認をする = to do a breathing check

It is a very noun-heavy, procedural style of Japanese, which is common in instructions, manuals, and emergency/medical contexts.

What does の mean here?

Here, の connects 呼吸 and 確認.

So:

• 呼吸の確認 literally means confirmation of breathing
• more naturally in English: checking breathing

This use of の is very common in Japanese. It often links two nouns, where the first noun describes the second.

Other examples:

• 名前の確認 = confirmation of name
• 安全の確認 = safety check
• 体温の確認 = checking body temperature
