| [ Summary ] |
Since neither chronic respiratory diseases, such as chronic obstructive pulmonary disease (COPD), bronchial asthma and restrictive ventilatory impairment nor sleep apnea syndrome (SAS) is rare, COPD and SAS can occasionally coexist. An association of these two diseases has relatively profound nocturnal hypoxemia, compared with each alone, and also leads to the development of right ventricular failure, so-called cor pulmonale. Continuous positive airway pressure (CPAP) or non-invasive positive pressure ventilation (NPPV) is useful for treatment of SAS. However, even though CPAP or NPPV has improved apnea/hypopnea episodes associated with SAS, some patients still display nocturnal hypoxemia. For treatment of such patients, the combination of CPAP or NPPV and supplemental oxygen therapy should be made available. |
