1. Introduction
Intended Use
The ConchaTherm® Neptune™ (also referred to herein as ‘humidifier’) is a respiratory humidifier
designed to heat and humidify respiratory gases delivered via endotracheal tubes, nasal cannula or
face masks to adult, pediatric and infant/neonatal patients. This system may be used with either
conventional (non-heated wire) breathing circuits or compatible (21-volt) Hudson RCI heated-wire
circuits.
The ConchaTherm Neptune can be used with ventilators, continuous flow systems, oxygen diluters
and blenders, adjustable nebulizer adapters for aerosol therapy, or non-flammable anesthesia gases
to help maintain patient body temperature.
