Thanks for your research Sue. I wish I could do the 7% and plan to try it again this time with a burst if Albuterol first. My pulmonologist said it helps some people to take a bronchodilator prior to the saline.

Soaking our devices in vinegar may or may not kill any bacteria on them. The best way to sterilize is boiling and most neb cups as well as the aerobika can be boiled. I learned from Arikayce that boiling in distilled water for 5 minutes will sterilize equipment
I soak in vinegar and soap after the morning airway clearance treatment and soak in soapy and then boil in distilled water in the evening, per Arikayce instructions.
