Ive been doing a few CO2 tables recently and am now absolutley convinced that in my case they reduce bronchial constriction. To test this I have been taking a peak flow measurement immediately before and after the table. Before the last 3 tables I have done I measured my peak flow to be 600 l/min (about normal for me), after the table this had increased to between 680 and 700 l/min (average of three measuremnts). Problem is I have not really been suffering from asthma lately so Im not sure if this data is particarly meaningful? Should I be taking any other measurments to make this more meaningful data?

I am guessing that no research has been done on the benefits of freediving breathing techniques for asthmatics? Ive been thinking about looking further into this. Can any one provide any useful links or info? What would be ideal is a large group of freediving asthmatics willing to do lots of PF measurements - any volunteers?

Also - slightly off topic but ive been reading a bit about a breathing technique known as Buteyko which is reportedly beneficial to astmatics. Does any one know anything about this and its possible applicatuion to freediving?

Sorry to ask so many questions. Any help much appreciated.
