Brief Summary
This is a study designed to measure, characterize and describe changes on pulse-oxymetry values produced as a result of deep breaths in patients with stable chronic hypoxemic respiratory failure.
Detailed Description
There is no standard way of measuring rest pulse-oxymetry in terms of depth of respiration. Rest pulse-oxymetry values are used in the clinical setting to make therapeutic decisions regarding the need...
