Recording peak flow meter readings

Demonstrate the peak flow graph and calculation for diurnal variation.

Peak flow variability features in many patients with asthma, and there are many ways to calculate it. Some calculations can be complicated for the clinical setting, e.g. the amplitude percentage mean. We will show you a simple approach for estimating peak flow variability.

This video demonstrates how to record peak flow meter readings and how to calculate the diurnal variation of the readings.
