Is 350 on peak flow meter good or bad?

A peak flow meter reading of 350 can be considered good, average, or low depending on your age, sex, and height.

For example:

For a healthy adult male, a reading of 350 L/min may be below normal.

For a teenager or a shorter adult female, it might be within the normal range.

To know if 350 is good or bad for you, compare it to your personal best or consult your doctor. If your reading is significantly lower than usual, it could indicate worsening Asthma or breathing issues, and you may need to adjust your treatment.
