I was diagnosed in 1998 with copd. I went into respiratory failure in 04/2009. I have smoked off and on and am still fighting that everyday. I have been treated many times for lung infections with antibiotics and steroids. I am on two maintenance inhalers, a med to help stop exacerbations. I also have started with sinus issues. 3 wks ago I started on the salt inhaler and it is giving me so much relief. Pls research this natural lung therapy for any lung issues from asthma, allergies, sinus, copd. My pulse ox used to measure 92-94%. It is now measuring 94-96%.
