Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of limited monitoring using a nasal-cannula flow signal to full polysomnography in sleep-disordered breathing.
Evaluate the utility of overnight monitoring limited to nasal cannula airflow and oximetry in the diagnosis of obstructive sleep apnea-hypopnea syndrome (OSAHS). ⋯ In subjects with OSAHS, analysis of the flow signal from a nasal cannula can provide an RDI similar to that obtained in a full NPSG.
