MINISPACER Adapter Particle Size and Dosing Characteristics
The MINISPACER dual-spray MDI adapter was evaluated for particle size and dosing characteristics using an 8 stage cascade impactor. The MINISPACER was connected to the cascade impactor with ventillation tubing, wye and endotracheal (ET) tube as they would be in a ventilator circuit. Air was drawn through the assembly at a flow rate of 28.3 l/min. The aerosol samples exited the ET tube into the cascade impacor and comprised the Total Delivered Dose.
