Hi there, I have understood your concern and I will suggest you the best possible treatment options.
First of all do not panic.
Please ensure that the patient is admitted in a tirtiary care institution for further treatment.
From your history it looks like case of pulmonary embolization.
Meaning obstruction in the lung blood vessels due to
blood clots or
amniotic fluid. This is uncommon but serious post delivery complication.
Due to this reason patient's
oxygen levels get affected and this leads to further problems.
Proper treatment, adequate ventilation and maintaining her
vital signs will help to get her out of this situation.
Please fully trust in your treating doctor.
May God bless you.
I hope this answer helps you.
Thanks
Dr. Purushottam Neurgaonkar
