Lasswade High School, 15 October 2016
A great day out for over 300 people who came to visit – and a great day for our demonstrators who enjoyed helping families measure their peak flow readings on our science festival stand. Thanks to Audrey, Tyra (pictured below) Eric and Teguh.
Peak flow readings tell us about our lung function – the rate at which we can blow out air from our lungs. In asthma our airways can be restricted – the walls of the airways tighten and mucus can build up in the airways making it hard for us to blow out air as quickly as we otherwise could.
Asking you to measure your peak flow readings twice a day for a couple of weeks can help to give doctors an indication of whether you may have asthma.

See the final chart – can you spot the clear patterns emerging?
Tip: Taller males generally have the highest readings – there are definitely groups of males and females visible in the adults here, with a few exceptions as you would expect. There appears to be less effect of gender on the children’s readings – but definitely the taller you get, the faster you can breathe air out of your lungs!
