Modified from ElHansy et al. [24]. SOLO vibrating mesh nebulizer was inserted in the ventilation circuit in the inspiratory limb of the BiPAP (before the Y piece of the dual limb ventilation circuit). The inhalation filter, to collect the TID, was then connected to the Y piece then the breathing simulator was connected. The bi-level ventilator was adjusted at two different pressures; IPAP/EPAP 20/5 cm water and IPAP/EPAP 10/5 cm water
