1. Ombra compressor with Aerobika.
2. I use Airsupra as needed, prior to my morning nebulizer.
3. 7% saline solution, morning and evening. My Humana PPO Medicare plan covers. Copay is about $2 for 100 4 ml vials. Takes 20 minutes.
4. I recently switched from the VIOS compressor to the Ombra. I like the Ombra better since the tubing and filter can be changed out easily.
