ANAPOD™ Active Heated Humidification System for Anesthesia

Now, finally, active heated molecular high humidity can be accomplished during general anesthesia without the expensive and bulky heated humidifier and water bag systems that are more properly suited for long­ term mechanical ventilators.

The ANAPOD™ system is a unique, self­-contained approach, eliminating manual temperature balance and humidity control. It is an easy, safe and effective method to actively heat and humidify inspiratory gases during anesthesia to help maintain thermoregulation and minimize post­anesthesia respiratory complications. Supplemental airway heat and humidity during anesthesia aids in the prevention of intraoperative hypothermia and can be used on virtually every intubated patient, even when other means of heating such as blankets or wraps are not feasible. Plus, active airway humidification helps to counteract the deleterious effects of dry, irritating anesthetic agents on the respiratory tract, thereby mitigating respiratory complications of anesthesia.

The innovation behind the ANAPOD Heated Humidification System for Anesthesia is its proprietary self­-contained water reservoir: in the tubing! A unique cellulose fiber wick and an extra low­ energy heating wire runs the length of the inspiratory limb of the anesthesia circuit.

ANAPOD Wick & Thermistor + Inspiratory Tubing Moisture


  • Quick and easy setup (2 – 3 minutes)
  • All inclusive packaging; complete anesthesia circuit including 100 mL bottle of sterile water
  • Inspiratory heat and humidity available in under 5 minutes
  • Safe, no risk of over­heating, even in ‘no flow’ state
  • Reabsorbing wick eliminates free flowing condensate and puddles of water in the tubing; no need for water traps
  • ANAPOD controller purchase options available 

Simply add ~75 mL of sterile water to the inspiratory limb (from the supplied 100 mL sterile water bottle), connect the circuit to the anesthesia machine and the ANAPOD controller, and you are ready to provide the benefits of airway heat and humidification to patients for up to 4 hours.

Filling and preparing the tubing

Filling and preparing the inspiratory limb of the circuit. See instructional video below for more information.

The heating wire warms and evaporates sterile water stored within the wick, providing 100% relative humidity at the desired temperature. Excess moisture is reabsorbed into the wick, eliminating the formation of free flowing condensate in the circuit. For procedures longer than 4 hours, additional sterile water is easily and quickly added when required.
