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 of supplemental oxygen. The primary goal of this study is to measure the change of pulse-oxymetry values during an experimental protocol of 10 deep breaths during one minute in patients with chronic hypoxemia. 45 patients will be studied in this first phase. In a second phase, secondary goals will be to measure Vd/Vt vent, noninvasive cardiac output and CT densitometry during the same deep breaths protocol in a subset of 13 patients with the grater increase observed in the first phase of study.
