I've raised £50000 to Help fund kurt russells air ambulance and health care needs

My brother had an accident yesterday whilst helping a friend move and fell from a 3 story building.
He has fractured his skull and has a bleed on the brain that needs to be operated on asap. He has also fractured his C5 (neck) and they have put him into a induced coma
However he is in the carribean and has no health insurance. The hospital will not carry on with the treatment untill they recieve £50,000, they will then air ambulance him to an appropriate hospital where they can operate immediatly. He will then require intensive care untill he is fit enough to fly home back to england. The costs just continue to increase. Any kind donations would be very much appreciated in helping us fund his health care needs.
Thankyou
