One major thing as she is from another state, currently in Bangalore she is getting continuous dry cough she is not able to sleep at night. Please reply how to stop this continuous dry cough .at least she can sleep properly at night. And nearby some physician (cardiology) given some medicine, there is no change with her. Please suggest mother is 57 years old and she is bit fat, some sounds coming while respiration from nose. I have shown her to doctor and doctor asked to test for the sleep test and then they told that is sleep apnea and referred for CPAP machine .so my question without CPAP machine is there any other way to make her proper as CPAP machine is too expensive.
