Maybe: It might be that when you reach ZERO on the counter, there is a little bit left, but not a reliable amount per puff. Therefore, when an inhaler is needed, if one has a new one, use the new one. If one has no new one, using the old one would be better than using nothing. One can get a refill when the pharmacy opens.
