In short

  • A peak flow meter measures how fast you can blow air out (PEF, in L/min).
  • Adults use a range like 60–800 L/min; children 50–400 L/min.
  • A 3-ball incentive spirometer is a breathing exerciser, often used after surgery or illness on medical advice.
  • These devices track and practise — they do not treat any condition.
