Changing the tubing, keeping it spotless, did not help prevent
infection for me. Stopping the
cpap treatment, is the only thing that prevented the chronic lung infections...and I always used the humitifer, which never helped prevent any infection... I regret ever having the sleep study and I regret what all the money and time it cost me, and the suffering of 3 years of lung infections...I am so done using the cpap treatment!
