肺活量

1. Origins, structure, and basic meaning

• Structure: 肺活量, read はいかつりょう, is a noun for the maximum volume of air that can be exhaled after a full inhalation.
• Basic usage: The capacity is measured in 肺活量を測定する, and its resulting value appears in 肺活量の数値.

2. Common pitfalls and similar expressions

• Capacity and numerical value
  • 肺活量 is the bodily capacity being measured, while 肺活量の数値 is the number recorded after measurement.
• Measurement and recording
  • The capacity is measured first and the result is then entered on a sheet, so the objects of the two actions differ.
