Looking to the future: The innovative technology at the heart of our NHS
What will the NHS look like over the next 70 years?
We've been looking at how technology is changing how the NHS works, and the impact it's having on patients.
Kelly and her sister Katie have a rare condition which affects their brains, their muscles and their sight.
Their home, in Amlwch, has been adapted to meet their needs.
But when Kelly fell ill last year, it looked like she might never leave hospital.
The ventilator - which provides essential life support - is a newer, smaller design.
Attached to Kelly's wheelchair, it's portable enough to mean she can live at home instead of having to remain in hospital.
The ventilator even gives her the flexibility to leave the house with her family.
In June, we had a rare opportunity to film in an operating theatre at the University Hospital of Wales during surgery, and watch the Da Vinci robot at work.
The machine - remotely operated by a surgeon - allows surgery to be more precise than traditional methods.
In Cardiff, it's been used in more than 800 prostate cancer operations since 2014.
The surgeon controls the machine from a nearby console, aided by a 3D image generated by cameras on the machine.
The machine mimics the surgeons hand movements, with the added benefit of greater dexterity and control than the human hand.
The equipment is expensive - costing more than £2m to install.
But those who use it say its benefits - both for the patient, and for our health service - are significant.
