What is a normal Peak Flow reading? 

Peak flow normal values are different for everyone and depend on gender, age and height.  They can also be affected by the time of day. According to the Royal College of Nursing, an adult’s reading should be between 400 and 700 litres per minute, with men’s readings generally higher.
