The volume of fluid consumed by the nebulizer divided by time (in µL s-1). Volume rate has also been called volume flow, flux, aspiration rate, aspiration flow or aspiration flux. The fluid consumed is either aspirated or injected. The volume rate of fluid consumption by nebulizers is usually between 10 and 100 µL s-1.
