HI-FLO is a reusable and highly efficient nebulizer, compatible with the great majority of compressors available in the market and with hospital central systems of pressurized air. Efficient with any kind of medication, HI-FLO nebulizer is fast thanks to the “second Venturi effect”: the open duct on one side entrains additional ambient air into the nebulizer increasing dramatically the nebulizing activity and the subsequent output to the patient. The residual volume is minimized due to the material of the inner walls of HI-FLO that let medication drops slide downwards to be nebulized again. HI-FLO passed compatibility test with Ambroxol, Salbutamol, Beclometasone Dipropionate, Acetylcysteine, Budesonide. HI-FLO is sterilizable in boling water. HI-FLO is also available in pre-packed sets for hospital use in different configurations.
