  • What is a peak flow meter used for?

  • A peak flow meter is primarily used by people who have lung conditions like COPD and asthma. It measures your airflow rate and can help you monitor the state of your lungs.

  • Can peak expiratory flow rate monitoring improve lung function in COPD patients?

  • Rationale: Chronic obstructive pulmonary disease, (COPD) is a major cause of morbidity and mortality in the United States. Peak expiratory flow rate (PEFR) monitoring could provide a daily objective measurement of lung function in COPD patients at home.

  • Can PEFR be used to measure lung function in COPD patients at home?

  • So, MD Rationale: Chronic obstructive pulmonary disease, (COPD) is a major cause of morbidity and mortality in the United States. Peak expiratory flow rate (PEFR) monitoring could provide a daily objective measurement of lung function in COPD patients at home.

  • How do I know if my COPD is blocked?

  • You can compare your past COPD peak flow meter readings to determine your category. When your airways are blocked, your flow rate is weaker. If you notice a significant fall in your peak flow speed, it may be caused by a flare-up of your lung disease.
