Beware the airway filter: deadspace effect in children under 2 years

Summary Background : Filters are increasingly used in breathing circuits as they protect the circuit from contamination and facilitate humidification of inspired gas. The use of filters, however, can augment the anatomical deadspace. This can be significant in children because they have much smaller...

Zusammenfassung:	Summary Background : Filters are increasingly used in breathing circuits as they protect the circuit from contamination and facilitate humidification of inspired gas.

Methods : Following institutional ethical approval, 20 healthy children
