The short answer is that some rain out is inevitable as a consequence of the temperature inside the tubing being higher than ambient room temperature. We find that the rain-out varies with the fluctuations in the environmental temperature (drafts etc.). The cooler the room the more heat will be lost and the more water vapor will rain-out. Even well humidified gas will cool over the length of the tubing. The heat source within the infant’s environment, either incubator or radiant warmer has some effect as well. We tend to just check it regularly and drain it as needed. If you are using the Fisher and Paykel humidifiers there are some techniques with manipulating the main temp and the chamber temperature that work quite well at compensating for heat loss, reducing rain-out and maximizing the mg/L of humidity the infant receives. We suggest you contact your F&P product representative regarding these manipulations. Their company has done some interesting lab and clinical research on humidi
