可以想成一個裝置站在人和空氣中間，接手呼吸這件事的一部分。有時候它接手整件事，把空氣直接打進吸不動的肺裡。有時候它只接手「把空氣弄乾淨」這一段，先把髒東西攔下來再讓你吸。兩種情況不同，但這個字指的都是同一件事：一台以呼吸為工作的裝置。From the word’s history
The source gives respirator as respirate plus -or, the ending that names the thing or person doing the action.
來源把這個字拆成 respirate（呼吸）加 -or（做這件事的東西或人）。所以字面只說了「處理呼吸的那個東西」，沒有指定它是機器還是面罩——這正好解釋了為什麼兩個差很多的東西共用一個字。
