Lung Function Tests

Personal FEV1 or PEF should be measured and recorded as the baseline reading. During routine reviews, PEF should be measured to: 

• Assess the response to a new treatment initiated, or
• Assess the response when a change of treatment is made (stepping up or down). 

Otherwise, regular or more frequent PEF monitoring is only recommended for patients with severe asthma.
