AirSpiral™ tube for less condensate*

The AirSpiral tube produces up to 93% less condensate* than a previous Airvo™ tube.

We’ve all seen it happen before. When warm, humid gas touches anything even a fraction of a degree colder than itself (i.e. dew point), it cools and generates condensate. We see it often in conventional breathing tubes made of thin, dense plastic: their surfaces are easily cooled by the outside air, resulting in unpleasant “rain-out”.

The AirSpiral heated breathing tube for Airvo 2 utilizes an advanced two-spiral design to help
protect against condensate.

AirSpiral tube

Conventional tube

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. Like a double-paned window, the inside and outside surfaces of the tube are physically separated, to reduce cooling and helps maximize the level of humidity remaining in the gas all the way to the patient.

Top 7 tips for managing condensation or rain-out, i.e. achieving Optimal Humidity for your patients

AirSpiral™ is our latest innovation in humidity delivery and condensation control. We know that some environments are more challenging than others, so here are our top tips to help manage condensation (rain-out) should it occur.

Use the right equipment for the job

Every part of our Airvo™ humidifier system plays a role in delivering Optimal Humidity to your patients. So, for best performance, use only Fisher & Paykel Healthcare’s products on your Airvo or MR850™ humidifier.

Why?
- For example, the Airvo humidity algorithm communicates with the heated breathing tube to power it and the tube provides temperature information (both within the room and inside the tube) back to the algorithm.
- The algorithm also accounts for the key characteristics of the Optiflow™ interfaces, i.e. we know the geometry of the interfaces and the nature of the materials, via our Evaqua™ technology. So, we know how to minimize condensate and deliver Optimal Humidity to the patient, for each interface in our range.

Place the Airvo below head height

That way, if condensation does form it’ll drain back towards the water chamber, not the patient.

Don't cover the heated breathing tube

Don't cover the heated breathing tube with clothing, blankets, sheets or pillows. Use the tube clip provided to attach it to the top of the bed coverings and allow it to run freely (and uncovered) between the patient and the device.

Check the environment

In-built sensors help compensate for ambient conditions but you can help by checking the following:

Is there a local source of cooling activated close to or blowing on the heated breathing tube, like a fan, air-conditioning unit, or air vent?
- If yes, are you able to remove or minimize the source, e.g. could a fan could be moved to the other side of the bed, away from the tube?

If condensation does form, drain it back towards the water chamber

Here’s how:

Disconnect the interface from the heated breathing tube.
Drain the tube by lifting up the patient end of the tube.
At higher flows it may be necessary to reduce the target flow rate to 30 L/min, or below, to ensure the water drains towards the chamber.

If condensation persists, consider turning the temperature down

Please note: this will also reduce the level of humidity reaching the patient, so try the other tips first.
