    Abstract:
    OBJECTIVE: To determine whether there was agreement between the short daytime ApneaGraph (dAG) and nocturnal ApneaGraph (nAG) in diagnosing sleep respiratory events initially and identifying the site of obstruction in airway. METHOD: Twenty four patients diagnosed OSAHS by PSG were enrolled. The apnea-hypopnea index (AHI), apnea index (AI), obstructive apnea-hypopnea index (OAHI), central apnea hypopnea index (CAHI), mixed apnea index (MAHI), lowest oxygen saturation (LSaO2) and the proportion of upper/lower obstruction (UPPER, LOWER) of patients were measured using both dAG and nAG. RESULT: There were no significant differences between nAG and dAG for the following parameters: AHI, AI, CAHI, MAHI, OAHI, the proportion of upper/lower obstruction, or LSaO2 (P>0.05). There were significant positive correlations between nAG and dAG with regard to AHI, AI, MAHI, OAHI, the proportion of upper/lower obstruction , LSaO2 except CAHI. CONCLUSION: The dAG has similar results with nAG in early diagnosis of sleep respiratory events and identifying the level of airway obstruction. The time-saving dAG is of considerable referential importance in diagnosis of sleep respiratory events and analysing the level of airway obstruction.
