Since your mother has been diagnosed with bronchiectasis consider airway clearance. To maximize airway clearance she'll need a compressor, nebulizer and hypertonic saline. All are available without a prescription. Below are links to nebulizer and compressor, both of which have been recommended by NJH. Hypertonic saline (3% or 7%) can be purchased on Amazon.
