If you have been advised by the surgery to submit your Asthma peak flow diary on a regular basis please use this form.

How to use your peak flow meter

• Put the pointer back to the first line on the scale – this is usually 60
• Stand, or sit upright (choose what’s easiest for you and always do it that way)
• Take a deep breath
• Make sure your mouth makes a tight seal around the mouthpiece
• Blow as hard and fast as you can into the meter
• Write down your score (the number next to the pointer)
• Do this 3 times in a row so you get 3 scores – and use the highest of these scores to fill in your diary
