The new AirSpiral™ tube for F&P myAIRVO 2 utilizes an advanced two-spiral design to help protect against condensate: The heating spiral contains heater wire to warm the breathing gas inside the tube. The insulating spiral uses a bubble of warmed air around the breathing gas to shield it from the outside environment. AirSpiral tube produces up to 93% less condensate* than a previous AIRVO tube. Less condensate may reduce interruptions to therapy.
