Thanks for your question on Health Care Magic. 
I can understand your concern. 
Honestly speaking, there is no cure for IPF (
idiopathic Pulmonary fibrosis). 
It is chronic progressive fibrosis of the lung. 
Following things should be done to achieve optimal treatment and reduce the rate of worsening of lung functions. 
1. Home 
oxygen therapy. Low dose oxygen should be given continuously for atleast 16-18 hours a day. This is the best treatment. 
2. Start perfinodone. It is the only available and US FDA approved anti fibrotic agent. It reduces rate of fibrosis. 
3. N acetyl cysteine is having excellent antioxidant, mucolytic and expectorant properties. And hence it is beneficial in IPF. 
4. Enroll her in 
Pulmonary Rehabilitation center where 
chest physiotherapy and deep breathing exercises are done. These will surely improve her lung functions. 
5. Vaccination with pneumococcal and Influenza vaccines is advisable to prevent recurrent 
respiratory tract infection. 
Hope I have solved your query. 
Wish you good health. Thanks.
