HAMILTON-HC emulates the human physiological mechanism -extensive, humid surface at body core temperature of the upper airways- when humidifying respiratory gases.
Following this principle HAMILTON-HC avoids excessive water temperatures and significantly enlarges the gas/water contact area. This enlargement is realized by an active water circulation continuously feeding heated humidification water to a specially designed exchange surface. Respiratory gas to be humidified is guided in opposite direction to the water. By this the gas becomes saturated with humidity and heated up to optimal conditions. Operational principle is evaporation and molecular transfer of humidity by means of a counterstream.
This results in an almost perfect humidification mainly independent of actual gas flow rates, gas inlet- or ambient temperatures.
