Thanks for your question on Health Care Magic.
I can understand your concern.
COPD is chronic, progressive inflammatory disease of lungs.
And in late stages, prognosis is not good.
She is also having valvular defect (leak in valves), this makes prognosis even more worse.
Life expectancy in this situation is less than 1 year.
But with optimal treatment, life expectancy can be increased to 1.5 to 2 years.
Optimal treatment includes
1. Long term low dose
oxygen therapy for atleast 15-16 hours a day.
2. Long acting inhaled bronchodilators and inhaled corticosteroid (ICS).
3.
Pulmonary Rehabilitation in the form of deep breathing exercises and
Chest physiotherapy.
So
consult pulmonologist and discuss about these optimal treatment options.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your mother. Thanks.
