Review on 8884719009 Voldyne 5000 Volumetric Respiratory Device by Bernard Her

I had Covid and had a terrible cough. Thank goodness I didn't have to go to the hospital because the cough medicine the doctor gave me and Dayquil made it through. Not an easy task. My daughter, a nurse, recommended this device to strengthen my lungs. At first I couldn't. He kept coughing with every breath. But I kept doing it little by little and now I can do the exercise without coughing. The exercise consists of 10 breaths to a comfortable level. Do this as often as possible throughout the day. You can increase the inhalation level as you feel stronger to do so without coughing. I highly recommend this device.
