Pressure sore cushions

Saw should read "raw"

If it helps and he is comfortable the nurse will never know!

Well - that was just what I was thinking!

You've mentioned the very reason I your post lucky. They are frowned upon by the NHS because they tend to be inflated too firmly and cause pressure damage to the tissue surrounding the original wound.
That being said, we used them in the Nursing Home without any problems.

We are soon to take delivery of an air mattress - all-singing, all-dancing, electrically-operated, NHS-funded, highly-expensive item. I think the blow-up cushion might be more cost-effective!

The only reason people advise against them, is that if over-inflated, they can cause more pressure. But as always, common sense should be used. Sounds like you are using it exactly right.

I suppose if it's under inflated it may have wrinkles, which can cause friction?
These things change all the time; I'm sure you're aware enough to keep a check that everything is as it should be.

He's sitting on it now and says he is far more comfortable; so we will bash on and just keep an eye on things.

Thanks for the advice.
