Assessment of Sleep Disorder Breathing Risk in Patients with Scleroderma


About this study

The purpose of this study is to retrospectively review the charts of 200 patients for whom overnight oximetry data, pulmonary function tests, as well as echocardiographic data have been obtained as part of routine clinical assessment. In so doing, the hope is to assess the risk of sleep disorder breathing, as evidenced by the oxygen desaturation index (ODI) on overnight oximetry assessment.
