EBME Forums Forums Maintenance Technical Assistance Single use vent circuits.

Do you use F&P 700 / 800 Series humdifiers ?
Do you use single use "heated" vent circuits?
If so what make / model?
Are they any good?
Any specific problems? (particularly rainout)?
Please feel free to comment
We are about to go to tender on these and would be grateful of any input if youve been there and done it all before. :p

KM,

I shall watch this posting with interest.
We use mainly two types, RT205 and the other I do not have to hand and fail to remember.

I have witnessed odd things happening with what I believe you term "Rainout" but am curious as to what your interpretation of this phenomenon is?

We have had many cases over the years with many different sets.
The only solution that has had 100% success is mounting the humidifiers as near to the floor as possible and keeping the runs of the tubes as straight as possible, so any rain out runs back to the reservoir.
The most difficult to solve is the neonatal breathing curcuits as the small bore on the nasal parts does not help.

Leonius. are you sure that your patient is receiving "Humidified" Gas.

Chris, The term Rain-out is used by F&P as a description of the Water saturated gas cooling to quickly. I.E. the water simply "Rains out" and condenses within the circuit. Contributing Factors (in my experience) usually include cooling fans, draughty rooms etc. Allowing a little additional overhead in the gas saturation helps too. F&P now. F&P have good data available on this subject.

KM we also use RT205 and don’t have much of a problem. Generally the same as the old re-usable Dunlop’s mate. Again the surrounding Environment is the most significant factor.

We use intersurgical circuits. we use the 2019 for vetilator circuits and 2037 when cpap is required. No problems with these circuits.

At Shrewsbury we use a mixture of Intersurgical and EME (Viasys) circuits. Intersurgical are good but suffer from long delivery times (up to six weeks) for circuits of my own design. Off the shelf products are quicker but have lengths and components that are not as good as my own. I overcome rainout by having the inspiration limb lagged with polythene sleeving. Intersurgical do this at no further cost. EME circuits are not so good for the Drager 8000 vent - the connectors are too restrictive and cause flow problems when using high frequency or other high flow situations. They are however, much quicker at supply.
