Condensation in compressor hoses

[Guest guest]

The condensation in the line is a common problem. Would you believe many

respirogists, physiotherapists, doctors and even the respiratory suppliers

seem unaware of this happening? I have had to explain the problem to many of

them. It was through talking, many years ago, to other families dealing with

CF that I learned the problem was common. They also taught us to get rid of

the moisture in the hose by removing the nebulizer at the end of the

treatment and letting the compressor continue to run blowing air through the

hose. Without the nebulizer attached, the pressure is not there to build up

the condensation and the air dries the hose.

The problem seems to be related to humidity and/or temperature. We have the

problem mainly in the spring and fall when neither the air conditioner nor

heat is running in the house. It has happened with three different brands of

compressors.

I cannot explain why it happens with the Tobi and not the Pulmozyme for you.

Could it be they are done at different times of day when humidity may be

different? Could it be a difference in type of nebulizer used (are they

different for the different meds)?

Still, it does concern me as to whether all bacteria has been filtered out

of the moist air before it condenses in the hose and whether some of the

moisture still goes into the nebulizer, carrying bacteria with it. We have,

however, continued to use nebulized treatments.
