My daughter is two has 'complex needs' and uses a ventilator during sleep (Asv bipap) the past few days she's had a cold. Nothing out. The ordinary as she often catches them but this time she is crying like evey 30minutes even through the night. It's so draining. No amount of calpol or vapour rub does the trick she's asking for us to take her vent off. We assumed this was because its a nasal mask and her nose is blocked therefore struggling to breathe however saline drops which clear her nose make no effect on her emotional reaction? Any ideas? Shes not in pain and has ever reacted like this before x
