East Lothian personal trainer fighting for her life in 'high risk' transfer from Vietnam to Singapore in next 24 hours
Davie Martin, a family friend, said Mekala was due to be moved in the next 24 hours in a "high risk" journey from the hospital in Hoi An, Vietnam, to Singapore.
Mekala, from Wallyford in East Lothian, has been in hospital in an induced coma fighting pneumonia since she fell ill last week.
He added that her mother Yvonne and stepfather Jimmy would not be flying with her and are in the process of obtaining flights to Singapore themselves.
Mr Martin said: "They have been made aware of the very high risk but this is the best option.
"It's in the hands of God or whoever is going to help Mekala make it.
"If all is successful they are hoping that a lung transplant will not be required. This could be subject to change however the doctors are confident this is the way forward."
"The plan is to Medivac her by cabin pressure at sea level, as she would not survive in a plane at normal pressure," said Mr Martin.
Initially suffering from a sore throat which Mekala treated with Strepsils, her health soon took a turn for the worse as she first developed bronchitis before contracting pneumonia.
More than £9,000 has been raised by well-wishers to help pay for the family's travel to south-east Asia.
