We assessed in a feasibility study whether telematic transmission using the Dream® and SleepBox® technologies for HPSG (with Skype® intervention if required) was associated with low PSG failure rate.Methods20 patients suspected of OSA were recruited. They underwent 1 HPSG (Dream®, Medatec®,Belgium) with the Sleepbox®, a wireless system containing an internet communication through a wifi/3G interface; equipped with a camera and a speaker for bidirectional audio/video communication via Skype®.The sleep lab nurse performed a discontinue monitoring of the PSG. In case of defective signal, she called the patient who had previously been educated to replace the probes/electrodes.ResultsView this table:Patients characteristics90% of the recordings were of excellent quality. We observed a 10% failure rate: 1 recording of poor quality and 1 failure of the Dream®. There were 2 successful Skype® interventions resulting in replacing the defective signals (nasal airway pressure and EEG). PSG signal visualisation was possible in 90% of cases but Skype® connection was problematic in 18% of cases. However, patients could be reached by phone to solve the problem.ConclusionReal-time attended HPSG through telematic data transmission is feasible and could be an interesting perspective to decrease the failure rate of home sleep studies even if some technical aspects need to be improved.
