Emphysema destroys some of your air sac walls, leading to fewer larger sacs that provide less area to absorb oxygen from the air you breathe. Over time, these changes can block normal air flow, resulting in a condition calledair trapping. ...
The normal oxygen saturation levels for people without chronic medical conditions is 95–100%. People with COPD usually have oxygen saturations of 88–92%. If levels fall below this range, you may experience symptoms of headaches, fast heartbeats (palpitations) and confusion, because your organs...
Oxygen levels should be monitored at every review. Patients with an SaO2 <92% should be referred to an oxygen assessment service. Normal and obstructive spirometryTime-volume curve (not to scale). The subject with normal lungs can empty most of their volume in the first second. Patients with...

the mechanism by which this occurs is not known. The role of air flow as an intervention has been explored and cold air directed on the face has been shown to reduce breathlessness induced by inspiratory resistive loading and hypercapnia in normal subjects (39) and in patients with COPD (43...
