How can a humidifier improve therapy comfort?
The airflow generated by a ventilator is often greater than what the body is used to. Using a humidifier with a ventilator can make a positive difference to therapy comfort by adding moisture and warmth to the air delivered by the devices, reducing the symptoms of dryness and congestion, and improving comfort and compliance.
Setting up a humidifier
Got questions about how to set up a humidifier? Find the answers here.
Q. Can the device sit on top of the humidifier?
A. For devices without an integrated humidifier, the device should always be placed either at the same level or above the humidifier to reduce the risk of water entering the device.
Q. Can the device be moved with water in the humidifier?
A. No. To ensure that water doesn't enter the device, disconnect the humidifier and drain the water before moving it.
Q. The patient has a full face mask. Will they need more water during the night?
A. A full face mask should not change the amount of water used each night. If the patient experienced mouth leak before switching to a full face mask, they could have been losing air and humidity through their mouth, in which case they should use less water.
Q. Does heated humidification wear out the mask and tubes faster?
A. No. The tubing supplied with devices can withstand far higher temperatures than the heat generated by the humidifier.
Q. Should the patient’s humidifier be turned on ahead of time to make sure the water is warm first?
A. Depending on patient´s needs, the humidifier may be turned on up to 20 minutes before use.
Q. Should the humidifier be used all year round or just in the winter months?
A. If the patient is having nasal congestion or dryness outside of the colder months, then it is recommended that they continue using a humidifier.

For the H5i™ heated humidifier
(Used with the S9 VPAP ST-A with iVAPS)
H5i humidification delivery is controlled by three inputs (ambient humidity, H5i settings and device flow) and adjusts the output to maintain consistent water delivery.
In general, start at a humidity level setting of 3, and adjust up or down by 0.5 to address any drying or rain-out (condensation) issues.
When using ClimateLine™ heated tubing, we recommend using Auto mode, which defaults to a Climate Control setting of approximately 27°C. From there, you can adjust up and down as necessary.
If using ClimateLine heated tubing in Manual mode, start with a humidity level setting of 3, and a heated tube setting of approximately 27°C. Adjust the humidity level up and down by 0.5 to address any drying or rain-out issues, and adjust the heated tube level up and down in 1° increments to find the most comfortable temperature setting.
For the H4i™ heated humidifier
(Used with the Stellar™ 150)
Start the setting at 3 and adjust for comfort.
