A question occurred to me today when I had to use 10 puffs of Ventolin in my Volumatic as a neb equivalent (seeing GP first thing Monday - I'm fine now, asthma just doesn't like this weather and I've been unwell with other stuff recently).
I'm sure I read somewhere on this site that when taking regular meds through spacer (i.e. my steroid inhaler), I have to do the two puffs separately with time between so that the second puff is medication rather than just propellant.
So why, if I'm told to put 10 puffs in the large volume spacer is this OK and the last 9 puffs aren't propellant?
Does that make sense?
