meri maa vantillation pe aj ak month ho gye doctor ka khna hai unke mind me oxygen nhi Jane ke karan brain damage hua hai or thora infection hai to kya ye recover ho skta hai?

Patients on ventilator support are prone to developing a ventilator-associated infection.

Does your mother run a high fever? Has the doctor mentioned anything like ventilator-associated pneumonia?

Such conditions need strictly monitored dose of antibiotics and in quite a few cases, it is curable too. But the percentage depends on the amount of brain damage due to oxygen loss.
