The Optimal Spacer for Young Children

The optimal spacer for young children would show the following features  

A volume of intermediate size, permitting the chamber to be emptied in a few breaths, but not so small that the bulk of the delivered dose from the pMDl impacts on the walls at the moment of actuation 

An efficient one-way inspiratory and expiratory valve system to assure opening and closing even during the shallow breathing of a young baby 

Minimal dead space in the valve and face mask
