A peak flow meter is a medical measuring device, enabling the calculation of air quantity expelled by the lungs by breathing into a graduated tube. Peak flow meters are primarily used in monitoring respiratory function in individuals suffering from respiratory failure and severe asthma. Given its easily-held form and simple use once the correct technique has been learnt, patients often use one on their own at home, recording the measurements obtained for examination by their doctor. In cases of asthma, this device notably enables children and their parents to assess the severity of an asthma attack and to know how to adapt their actions as a consequence.
