For whoever said about a hospice - I've never known a hospice set up to deal with a ventilated child. You need an ITU for that.
Hospices can take ventilated children. I have three colleagues who have experiences of working in Children's hospices and respite homes and they all have experience in caring for ventilated children. I also know Community Children's Nurses who have cared for ventilated children in their homes.
The ward I work on has a HDU Unit but not an ITU but the nurses are currently being trained in ventilator dependent care so they can look after children in their unit if ventilation is going to be needed for a suspected short term.
Although nurses do require specialist training for Vent usage it is possible to care for ventilated patients outside of an ITU or hospital setting.
That's just my experience of my Trust and surrounding areas, I don't know how or if it is done in other parts of the country. I imagine the child's health status also plays a role in the practically of whether children can be transported to their own homes or hospices for withdrawal of care as has been talked about a lot in these threads.
I imagine Charlie wouldn't be suitable for hospice/home withdrawal of care, not because he's ventilated but just because his other health complications make it too much of a risk to move him.
I once looked after a child with cancer, she was 12, the decision had been made to withdraw treatment because there was no hope of recovery and when she got really ill with us the parents asked to take her home so she could pass away there. The little girl wasn't ventilator dependent but she was very, very unwell and after much deliberation the doctors said she could go home because it was obvious how much the parents wanted it. Unfortunately it was a 4 hour drive and she sadly passed away in the ambulance on the way home - it was very, very sad and I think the parents felt a lot of guilt for putting her through the journey, even though it was unnecessary guilt in everyone else's eyes. I imagine they'd wanted her to have a peaceful death in her own home surrounded by her family and when that didn't happen and she instead died in the back of an ambulance her parents were heartbroken and questioned their decision to move her. They did what they felt was right at the time though and I hope that as time passed they learnt to let go of that anger they felt at themselves.
