How Can COPD Be Treated?

I am inquiring for a friend who does not have access to a computer. He is an 82 yr. old man who has been in good health until about 8-10 years ago. Hi is not on any oral medications but has developed COPD because of second hand smoke exposure from living with a smoking partner and Casino smoke for 30-40 years. He has never used tobacco products personally. He uses an inhaler and breathing device at home for respiratory symptoms of wheezing and shortness of breath. He complains of constant hissing sounds in his ears . A recent hearing test did not reveal any significant hearing impairment. It is so bothersome that it often awakens him from sleep. His PCP says he has never heard of this and has not recommended and advice or recommendations for referral.You may respond to my email: YYYY@YYYY . Thank you for any medical insight you can provide. I can assist him by taking him to appointments etc and advocating for him with his PCP. I am an RN Patient Navigator.
