How to Use This Calculator
- Enter the fill volume (mL) -- the amount of solution loaded into the nebulizer cup.
- Set dead volume (mL) -- the residual volume remaining when the unit sputters (typically 0.5-1 mL).
- Enter the nominal drug dose (mg) and driving gas flow (L/min).
- Review estimated treatment time (minutes), effective dose delivered, and delivery efficiency (%).
- Use lung deposition estimate to compare nebulizer efficiency to inhaler alternatives.
