I do not own a pulse oximeter or peak flow meter and therefore cannot enter these parameters. Is it important?

The pulse oximeter helps you determine arterial oxygen saturation. Lung function is checked by a simple peak flow meter test. These values can be important to monitor deterioration – especially for doctor visits these parameters can be helpful. So if you don’t have a pulse oximeter or peak flow meter, you could check with your doctor to see if that is useful in your case. Of course, Kata® is also helpful for your inhalation therapy without recording these values.
