Abstract
UNLABELLED: To evaluate role of overnight domiciliary apneagraph in diagnosing severity of sleep apnoea. Prospective audit of 37 patients with Epworth sleepiness score over ten and all patients with history of sleep apnoea presenting to ENT outpatient clinic investigated with apneagraph. Data analysed initially with pulse oximetry findings alone followed by analysis with full apneagraph findings. RESULTS: Data analysed with pulse oximetry alone showed 31 patients to be simple snorers, but on analysis with apneagraph, 11 of these were shown to be suffering from moderate and one with severe sleep apnoea. There was no correlation between Epworth sleepiness score and severity of sleep apnoea. CONCLUSION: Management plan can be more evidence based by using apneagraph as a mini sleep study in investigating patients with history of obstructive sleep apnoea. Apneagraph could also be used in diagnosing the level of obstruction in snorers; however, this aspect needs further studying.
