How is this sentence read?

It is read:

きどう を かくにんして、じんこうこきゅう と きょうこつあっぱく を れんしゅうする。

Word by word:

• 気道 = きどう
• 確認して = かくにんして
• 人工呼吸 = じんこうこきゅう
• 胸骨圧迫 = きょうこつあっぱく
• 練習する = れんしゅうする

Why are there spaces in the sentence? I thought Japanese usually does not use spaces.

That is correct: Japanese normally does not use spaces like this.

The sentence would normally be written as:

気道を確認して、人工呼吸と胸骨圧迫を練習する。

The spaces in your version are just a learning aid to make the parts easier to see.

Why is を used twice?

Because there are two different objects in the sentence.

• 気道を確認して = check the airway
• 人工呼吸と胸骨圧迫を練習する = practice artificial respiration and chest compressions

So the first を marks 気道 as the object of 確認して.

The second を marks 人工呼吸と胸骨圧迫 as the object of 練習する.
