pwcbird CPAP stands for 'Continuous Positive Airways Pressure'. It means that Katherine is still receiving air/oxygen should she need it and it's kinda forced through the mask/prongs up her nose rather than down her vent tube into her lungs (so it's less invasive). It's the go between, between ventilation and nothing at all.
It means she's doing the breathing herself (rather than the ventilator) but the machine keeps her lungs a little bit open rather than her trying to open her 'tight' little lungs (remember girls, everything for Katherine is immature and not ready to be used).
The nurse compared it to blowing up a balloon...once it's been up it's easier to blow up again but the initial blowing up is hard...so, katherines lungs are stiff and the machine keeps the alvioli open, but the breathing is her on her own
Hope that clears that one up!
Hoping that kaz1967 is doing ok
I wonder if social services know that jeanjeannie keeps her little ones on a building site?
Oh, a pic of katherine on her CPAP for anyone interested is posted
