Is tapping jet nebulisers worthwhile?
An in vitro system was used to study the effect of tapping a jet nebuliser on the dose delivered to patients. Using a 2 ml fill, effective drug delivery had ceased by 3 minutes but a further 38% was delivered to the filter by 5 minutes if the chamber was tapped.
