Hello, my mom is 84 years old and she has been having difficulties breathing, coughing with mucus. She's been taking ventolin HFA 90 mcg inhaler, 2 puffs every 4 hours, and Advair HFA 115-21 mcg inhaler 2 puffs twice a day. She's also taking Loratadine 10 mg, once a day. With the ongoing heatwave in northern CA, 90-100 degrees but we don't have Air conditioner in the house, I'm wondering if we should get a portable AC or an air purifier? Or anything we can do to help? Much appreciated, thanks!
