Re: Does Asthma &/or Chronic Bronchitis cause hyperventillation?
In smokers, chronic bronchitis is considered chronic obstructive pulmonary disease, but I don't know if you smoke. For those of us with COPD, pursed lip breathing (PLB) is invaluable. We can get the oxygen in fine, but are unable to exhale all of it--thus we keep bringing in more and more and it 'stacks' in the diagrapham causing shortness of breath. Try breathing in for the count of four and gently exhaling (like blowing out a candle) to the count of 8. This also helps rid us of excess CO2. It's wonderful for shortness of breath, especially during exercise, but takes some practice.
Has your oxygen level been checked with the pulse oximeter on your finger?
