Welcome to Peakflow


The aim of the Peak Flow Diary website is to help everyone with asthma to lead a healthier and happier life.

By monitoring and tracking your asthma you will be able to see how your asthma fluctuates on a daily basis. To monitor your asthma you should record your peak flow reading twice a day. A peak flow reading is a measure of how much air you can expel from your lungs. This is measured using a peak flow meter.

By regularly recording your peak flow reading your doctor will be able to use the data to ensure that you are taking the correct medication and fine tune the dosage when required.

The peak flow diary website will help you to do this by allowing you to record peak flow readings, medication changes and life factors. The readings are then graphed to help visualise how you asthma varies day to day.
