BNP Chairperson Khaleda Zia's doctors said she can be taken abroad once she becomes consistently stable.
With oxygen support, her oxygen saturation level remains 100 percent and she needs one litre of oxygen an hour, said a doctor involved with Khaleda's treatment.
The doctor, who is in a 10-member medical board, said the former prime minister's oxygen level fluctuates without oxygen support, but the dependency has decreased.
"We advised the family members to take madam [Khaleda] abroad once she gains more stability," he told The Daily Star yesterday.
Her blood pressure was 120/80 at 5:00 pm yesterday when her respiratory rate was 15-20 per minute.
