Exclusive ClimateLine heated tube

The ClimateLine heated tube is the key technology in the Climate Control system. It contains revolutionary technologies never before seen in CPAP tubing that enable the delivery of Climate Control and unsurpassed patient comfort.

The ClimateLine tube includes a sensitive heating circuit, which is automatically controlled by the Climate Control algorithm to deliver a constant comfortable temperature at the mask. Located at the mask end of the tube, a sensor measures the temperature of the air leaving the tube. Unique to ResMed, this feature offers complete temperature and comfort control.

Rainout protection without compromise

With traditional humidification systems, as the temperature in the room drops, so does the temperature of the air inside the tube. At lower temperatures, the amount of water vapor that can be held by the air decreases, and condensation (rainout) can form in the tube.

The ClimateLine tube maintains the temperature of the air delivered to the patient. This ensures that rainout is avoided even if the temperature in the room drops during the night.

By keeping the air temperature in the tube constant, the Climate Control system can automatically adjust to changes in ambient conditions to maintain a constant, comfortable humidity level. Rainout is avoided without needing to reduce the humidity delivered.

Set and forget

Because the system measures temperature at the mask, the temperature you feel will remain at your preferred setting, regardless of changes in ambient temperature or humidity.

Smaller, slimmer, sleeker

The ClimateLine heated tube offers increased flexibility, more sleeping comfort and less mask drag.

 

Climate Control – Humidification with Heated Tube White Paper

Enhanced H5i humidifier

The H5i heated humidifier delivers market-leading performance.

Designed to seamlessly integrate with the S9, the H5i offers relief from dryness and congestion.

Out of the box humidification

The S9 automatically detects the H5i when it is connected. Once you have connected your H5i, you’re ready to go.

Onboard intelligence

The H5i senses ambient temperature and humidity in the bedroom.

Two water tubs

The H5i is available with a standard or cleanable water tub:

• The standard tub is a one-piece tub that is designed to be replaced at least every six months, or as recommended by the healthcare provider.
• The cleanable water tub is easy to disassemble, clean and reassemble. It is also suitable for multi-patient use in a clinic, hospital or sleep lab.

Why do you need humidification during therapy?

When you breathe normally, your nose and upper airway add heat and moisture to the air. By the time it reaches your lungs, air should be at body temperature (37°C or 99°F) with 100% relative humidity (44 mg/L).

During therapy, higher air pressure can overwhelm your upper airway’s ability to heat and humidify the air. Colder, dryer air can cause a sore throat, dry nose, mouth or throat, nasal congestion and a runny nose.

30 - 70% of patients experience these symptoms.

What’s wrong with traditional humidification?

Traditional humidifiers:

• Don’t monitor air at the mask
• Don’t react to changes in air flow
• Don’t react to changes in ambient weather conditions
• Don’t prevent rainout

What makes Climate Control better?

Climate Control uses an intelligent algorithm that controls the H5i and the ClimateLine tube to deliver constant, comfortable temperature and humidity levels during therapy.

Designed to address the limitations of traditional humidification, the Climate Control system provides protection from rainout and ensures maximum comfort.

While you are sleeping, Climate Control automatically controls:

• Temperature of the delivered air: The temperature sensor located at the mask end of the ClimateLine tube monitors the temperature of the air delivered to the patient.
• Humidity level: For each temperature setting, the Climate Control system delivers a constant amount of water vapor, or absolute humidity.
• Rainout: The humidifier and heated tube work in harmony to deliver air at a constant level of humidity and temperature – even as the ambient and treatment conditions change.

Climate Control also automatically adapts to:

• Changes in flow rates
• Changes in ambient conditions such as room temperature or humidity level

The result is unequalled comfort and optimum therapy.

What is Humidity?

A Quick Tutorial

Humidity is the amount of water vapour in the air. You have probably talked about humidity and hot weather, for example:

• When there is a small amount of water vapor in the air (low humidity) it is often referred to as a "dry" heat
• When there is a lot of water vapor in the air (high humidity) it is commonly said that it is "muggy" or "humid"

There are two ways of measuring humidity:

• Absolute Humidity – the actual amount of water vapor in the air
• Relative Humidity – the percentage of water vapor in the air compared to the air’s capacity to hold water vapor

Did you know?

Relative Humidity varies with temperature. The higher the temperature, the more water vapor the air can hold. The cooler the air, the less water it can hold.

That is why when warm air cools as it travels down the tube, condensation forms on the inside of the tube and mask in a CPAP system. This condensation is knows as rainout.

Rainout

Rainout is the water, or condensation, that collects in your mask or tubing. It is a common side effect of humidification.
