Introduction Ambulatory sleep, cardio-respiratory devices, or level 3 sleep studies have been used for screening and diagnosis of sleep apnoea in the adult and paediatric population. The advantages of using a level 3 portable sleep monitoring device include being able to expedite diagnosis, ease for the patient and family members and being 50% the cost of an in-patient level 1 PSG. Literature is limited on the use of these devices in paediatrics, this includes patient/guardian usability and satisfaction as well as the ability to assess sleep disorders.

From May 2018 we produced and distributed a questionnaire to address these issues.

Methods The questionnaire comprised of 4 questions about the device and the sleep study process. There are 3–6 options for each answer (see table 1). We also recorded technical failures using the report generated by the DOMINO LightTM Software auto-analyser. This includes failure rate of the pulse oximeter, respiratory bands and nasal cannulae.

Results At the time of analysis, 30 completed questionnaires demonstrated that the majority (93%) would prefer a home study compared to an in-patient study. At the time of analysis, 31 completed questionnaire revealed that 48% of guardians found the most challenging part of the home set up was the nasal cannulae. Figure 1.

Discussion The preference for home studies suggests this method of monitoring and diagnosing patients could be beneficial for the future of our service. This is in keeping with the desire to deliver modern healthcare within the home setting – so called ‘hospital at home’.

The nasal cannulae provides important information for analysis and diagnosis of the study. For further analysis, the frequent technical failures which could occur in the sensors from Question 2 (table 1.) could be analysed.
