“…PTT has been suggested as a surrogate marker of inspiratory effort [23]. It has been documented as a reliable marker of inspiratory efforts in sleep studies performed in children with sleepdisordered breathing [9,24,25] and in adults [23,26]. Our data support the use of PTT as a marker of inspiratory effort under bi-level positive pressure ventilation.…”

Among the respiratory events that may occur during nocturnal noninvasive ventilation (NIV), differentiating between central and obstructive events requires appropriate indicators of respiratory effort. The aim of the present study was to assess pulse transit time (PTT) as an indicator of respiratory effort under NIV in comparison with oesophageal pressure (P(oes)). During wakefulness, PTT was compared to P(oes) during spontaneous breathing and under NIV with or without induced leaks in 11 healthy individuals. In addition, the contribution of PTT versus P(oes) to differentiation of central from obstructive respiratory events occurring under NIV during sleep was evaluated in 10 patients with obesity hypoventilation syndrome (OHS). From spontaneous breathing to NIV without leaks, respiratory effort decreased significantly whereas, with increasing level of leaks, there was a significant increase in respiratory effort. Changes in PTT accurately reflected changes in P(oes). In OHS patients during nocturnal NIV, intraclass correlation coefficients between P(oes) and PTT were 0.970 for total number of events and 0.970 for percentage of central events. PTT accurately reflects the unloading of respiratory muscles induced by NIV and the increase in respiratory effort during leaks. PTT during sleep is also useful to differentiate central from obstructive respiratory events occurring under NIV

“…Notwithstanding this, previous studies have failed to demonstrate differences in electroencephalographic arousals between children with PS and children who have never snored [30]. However, other assessments of sleep fragmentation and disruption like (1) sleep pressure score [31]; (2) cycling alternating patterns [32]; or (3) subcortical arousal detected by beat-to-beat blood pressure [33], heart rate [34,35], and pulse transit time [36][37][38] may help better to understand underlying mechanisms.…”

Primary snoring in school children: prevalence and neurocognitive impairments

et al. 2011

Purpose: We aimed to investigate the prevalence of primary snoring (PS) (23% vs. 12%), and spelling (33% vs. 20%; all P values <0.05). PS was a significant risk factor (odds ratio; 95% CI) for hyperactive behaviour (2.8; 1.6-4.8), inattentive behaviour (4.4; 2.4-8.1), as well as daytime sleepiness (10.7; 4.0-28.4). PS was also an independent risk factor for poor school performance in mathematics (2.6; 1.2-5.8), science (3.3; 1.2-8.8), and spelling (2.5; 1.1-5.5

“…c) Pulse transit time is the interval between the R wave of the electrocardiogram and the arrival of the photoplethysmographic pulse at the finger. Published evidence supporting its use is limited (class III-IV) [164,165]. d) Low sensitivity and specificity for diagnosing OSAS by the OSAS score were found in a meta-analysis [166].…”

Obstructive sleep disordered breathing in 2- to 18-year-old children: diagnosis and management

et al. 2015

This document summarises the conclusions of a European Respiratory Society Task Force on the diagnosis and management of obstructive sleep disordered breathing (SDB) in childhood and refers to children aged 2-18 years. Prospective cohort studies describing the natural history of SDB or randomised, double-blind, placebo-controlled trials regarding its management are scarce. Selected evidence (362 articles) can be consolidated into seven management steps. SDB is suspected when symptoms or abnormalities related to upper airway obstruction are present (step 1). Central nervous or cardiovascular system morbidity, growth failure or enuresis and predictors of SDB persistence in the long-term are recognised (steps 2 and 3), and SDB severity is determined objectively preferably using polysomnography (step 4). Children with an apnoea-hypopnoea index (AHI) >5 episodes·h, those with an AHI of 1-5 episodes·h −1 and the presence of morbidity or factors predicting SDB persistence, and children with complex conditions (e.g. Down syndrome and Prader-Willi syndrome) all appear to benefit from treatment (step 5). Treatment interventions are usually implemented in a stepwise fashion addressing all abnormalities that predispose to SDB (step 6) with re-evaluation after each intervention to detect residual disease and to determine the need for additional treatment (step 7). @ERSpublications Management of obstructive sleep disordered breathing in childhood should follow a stepwise approach
