Yesterday I thought I'd try some exercise for the first time since I started with the last chest infection. Big mistake, unfortunately as my chest got very tight and I ended up using 10 puffs of ventolin. It did the trick and the tightness went but my peak flow still wasn't that high. Before exercise was 460, after exercise 380, 10minutes after ventolin 480, my personal peak flow is 570 but even on oral steroids I haven't got higher than 480-500. I just wondered if 10puffs should have made my pf higher?
Before the chest infection I was getting 550 quite regularly. I just wondered if my best had just reduced now?
