“…Children with a lot of movement during sleep may benefit from an ambulant PG instead of home PG. Furthermore, if the clinical suspicion is not supported by the results of the home PG a PSG is beneficial, which includes sleep parameters and video recordings to improve diagnostics and minimise the need of retake 20 . A previous study has shown that parents think home PG is relatively unproblematic to perform 3 .…”

“…Lower reliability of automatic scoring may be due to difficulties in registration of hypopnoeas causing arousal without decreased oxygen saturation. It may also be caused by difficulties in determining the actual sleeping time due to the interference by physical activity and lack of sleep parameters compared to PSG 20 . Accordingly, impaired nasal airflow was scored by the use of cRIPflow, 12,13 so the otherwise uninterpretable recording could be used and interpreted in the present study.…”

AimThe aims of the study were to examine the signal quality (SQ) of home polygraphy (PG) in children and adolescents and to compare automatic and manual scoring of the PGs.MethodsClinical Trials Registration: NCT04964830. Participants and caregivers were instructed to set up the equipment and perform home PGs themselves. The PGs were analysed according to SQ and their interpretability and differences in automatic vs. manual scoring regarding apnoea–hypopnoea index (AHI), apnoea index (AI), hypopnoea index (HI) and oxygen desaturation index (ODI) were examined.Results54 healthy children aged 9–14 years participated in the study. 86% of the PGs were interpretable with mean SQ of 79.1% (CI 95%: 73.5%; 84.8%). Significant differences between the automatic and manual scoring were found for AHI, AI, HI and ODI (p < 0.0001).ConclusionHome PGs of children and adolescents are feasible to be performed with good SQ. Significantly higher markers of sleep‐disordered breathing were achieved in the automatic scoring in comparison with the manual scoring.

“…Overnight polysomnography (PSG) in a sleep laboratory is the reference method for the diagnosis of OSAHS. Respiratory polygraphy (RP) is a reliable alternative to in-lab PSG [10,11], but tends to underestimate OSAHS severity, and also raises the issue of its availability. Sleep recordings allow identification of central and obstructive apneas, hypopneas, and sleep arousal due to respiratory effort.…”

Objectives: Because access to sleep recordings is limited, there is a need for new reliable diagnostic tools for pediatric obstructive sleep apnea-hypopnea syndrome (OSAHS) diagnosis. A score calculated from a 30 minutes-home sleep videotape recording has already been proposed in 1996 with interesting results. The main objective of this pilot study was to assess the reliability of a similar score applied to reference PSG video recordings and calculated on two different time windows (30 and 10 minutes). Methods: Sixteen children suspected of OSAHS, aged between two and ten years, underwent video recording during overnight PSG. Video analysis was made during the second complete sleep cycle. A 30-minute risk score (RS30) and a 10-minute risk score (RS10) were established by analyzing seven parameters. The RS30 and RS10 were correlated with clinical examination data, a sleep questionnaire, the obstructive-apnea-hypopnea index (OAHI) and the oxygen desaturation index (ODI) from synchronized PSG results. Results: There was a significant correlation between both the RS30 and RS10, the OAHI and ODI. A RS30 ≥ 6.09 was predictive of an OAHI ≥ 5 per hour with a sensitivity of 83% and a specificity of 90%. A RS10 ≥ 6.50 was predictive of an OAHI ≥ 5 per hour with a sensitivity of 67% and a specificity of 100%. Conclusion: A risk score based on PSG video recordings shows a good correlation with PSG results, confirming previous reports. Further work should focus on applying this risk score to home sleep video recordings for the diagnosis of pediatric OSAHS.
