WebMar 10, 2024 · Interpreting PEFR. PEFR is measured in litres per minute (L/min). The expected peak expiratory flow rate will vary depending on the patient’s age , sex and height (Figure 1). A normal reading is approximately between 400 – 600 L/min. Causes of a reduced PEFR include asthma (most common) and COPD. WebSubjects kept diaries of morning and evening PEFR values and use of rescue bronchodilator. Results: Formoterol and salmeterol both caused a significant increase in FEV (1) (0.45L [95% CI 0.01, 0.80] and 0.27L [95% CI 0.08, 0.62] respectively).
