Add FEV1 as a measurement for asthma. please feel free to email me at firstname.lastname@example.org if youre curious how I use this. - James
FEV1 is similar to peak flow except instead of the maximum volume you push out at any instant, it is the total measure of volume pushed out in one second. You can buy devices to measure this at home and it is a useful metric for me and my pulmonologist in understanding how my medications affect my asthma.
what you mean
