I'm studying a healthcare course, currently studying oxygen and we all had a go at the peak flow reader My class mates were getting readings of 450 to 500 but I couldn't get higher than 300 even with using good technique. I tried several times and got between 270 to 300. A lad who has asthma was getting over 400.
I'm female but still all the females got much higher than me. I've never been diagnosed with asthma but I do have chronic rhinitis/nasal polyps condition which started when I was 19 but as far as I know my lungs have always been fine. I go running/do interval sessions with no probs although I am always at the back and get poor times/don't have the stamina the others have. I don't feel like I have problems breathing though, a few people have said that I was wheezing when running but I just hear myself breathing loud I feel ok.
Should I be worried about a peak flow of this low as a female ?
