Just wanted to mention that using a cannula to deliver to oxygen to my lungs has caused my nasal passages to dry out and bleed. I was not initially aware that this would occur but found a moisturizing saline nasal gel called AYR no drip sinus spray. The bleeding stopped and has not returned. There are plenty other moisturizing nasal sprays out there....this was cheap and local! Tell us what you use to help solve your ordinary everyday issues on living with PAP.
