|Shown here is nebulizer distal to acapella.|
Studies show this is not best method.
My answer: A recent study by Mesquita et tested airway distribution by placing the nebulizer distal to the acapella as the manufacturer suggests, and airway distribution by placing the nebulizer between the acapella and the and the patient airway. The researchers concluded that placing the nebulizer distal to the acapella resulted in less lung distribution compared to placing the nebulizer between the acapella and the patient's airway. \
