(All right. Let's do CPR to her.)

In the real world, it's just a dummy torso for practicing CPR, but in the VR world, it's a patient named Ann.

(Well done. Ann is now saved.)

It's just one of the advances virtual reality can bring to the health care field.

"There're so many ways that VR can be used, not just for training in education, but they actually help treat patients so to reduce pain or to get people who are confined to one location because they're sick, inexperienced to socialize with the outside world or to help elderly people experience things that they no longer can.

So I think VR has so many great applications in health care and we're just only scratching the surface of the potential."

This sequence allows people to see through the eyes of a patient with macular degeneration, a condition that affects both sight and hearing.

This program attempts to illustrate what the dementia looks in fields like.

"Dementia is a difficult condition for people to get there, to get their heads run.

There're lots of mist conceptions that surround dementia.

So in order to raise our awareness and challenge those once mist conceptions, we developed virtual reality experience to try to put people in the shoes of someone who is living with dementia and try to show them how everyday life can be more challenging and just how some of the symptoms of dementia can affect the way that they go about every lives."

"So you (are) now in the Afghan world village, so you now can look around a little bit, you are on little bridge."

VR can also give psychologists a new tool to help their patients work through issues like PTSD.

"What we do is in addition to just closing your eyes and thinking about it, we give patients a way to see some of their experiences, to hear some of their experiences.

And it's something that the condition can use as additional tool as part of the overall treatment."

Researchers who are trying to incorporate these technologies into medical practice say they're just getting started.

"So here we have the construction of the heart valve, on close then we can go many other areas and start to look how cancer itself interact for example.

You know, conditions that, you know, on the surface we don't see."

The VR hospital just ended its running in London, but the melting in VR and medicine is just beginning.
