Apparently the FDA and the EPA decided that the traditional albuterol inhalers were dangerous to the ozone as they contained CFC (Chlorofluorocarbon). The new albuterol uses HFA (hydrofluoroalkane).

Have any of you seen these new inhalers? Iíve heard that they do not mate to traditional anesthesia circuit spacers. Is there any truth to this? Have any of you noticed a problem?
