“…Another limitation that should be noted is that the portable polysomnography system used in this study has only two EEG leads. Therefore, the recommended montage by the American Academy for Sleep Medicine cannot be used with this and other portable devices, and here may have led to small increases in scoring of stage 1 NREM in place of stages 2 and 3 NREM (Berry et al., ; Ruehland et al., ). In addition, use of the two EEG leads here prevented the use of more sophisticated EEG analyses (e.g., power in relevant frequency bands).…”

Sleep is an important component of motor memory consolidation and learning, providing a critical tool to enhance training and rehabilitation. Following initial skill acquisition, memory consolidation is largely a result of non‐rapid eye movement sleep over either a full night or a nap. Targeted memory reactivation is one method used to enhance this critical process, which involves the pairing of an external cue with task performance at the time of initial motor skill acquisition, followed by replay of the same cue during sleep. Application of targeted memory reactivation during sleep leads to increased functional connectivity within task‐related brain networks and improved behavioural performance in healthy young adults. We have previously used targeted memory reactivation throughout the first two slow‐wave sleep cycles of a full night of sleep to enhance non‐dominant arm throwing accuracy in healthy young adults. Here, we aimed to determine whether application of targeted memory reactivation throughout a 1‐hr daytime nap was sufficient to enhance performance on the same non‐dominant arm throwing task in healthy young adults. Participants were allocated to either nap or no nap, and within those groups half received targeted memory reactivation throughout a 1‐hr between‐session period, leading to four groups. Only participants who slept between sessions while receiving targeted memory reactivation enhanced their throwing accuracy upon beginning the second session. Future studies will aim to use this technique as an adjunct to traditional physical rehabilitation with individuals with neurologic diagnoses such as stroke.

However, the American Academy of Sleep Medicine respiratory rules for children uses ODI 3% (even if SpO 2 nadir is >95%) and would score central apnoeas or hypopnoeas followed by a desaturation from SpO 2 100 to 95% on PSG …”

Aim The aims of this study are: (i) to survey the knowledge of paediatric clinicians using overnight continuous pulse oximetry data to guide management of infants with chronic neonatal lung disease (CNLD); (ii) to assess the ability of paediatric clinicians to interpret overnight continuous pulse oximetry data; and (iii) to describe the overnight oximetry interpretation practices of paediatric respiratory specialists. Methods Paediatric clinicians from three tertiary teaching hospitals completed an anonymous survey regarding overnight continuous pulse oximetry in chronic neonatal lung disease. Using a modified Delphi technique, paediatric respiratory specialists participated in a concordance exercise and discussions to establish consensus interpretations for 25 oximetry studies. Paediatric clinicians were invited to complete the same exercise as a comparison. Results Self‐rated knowledge from 74 surveyed clinicians was proportional to clinical experience. Twenty paediatric clinicians and nine paediatric respiratory specialists completed the oximetry exercise with scores of 64% (κ = 0.25) and 80% (κ = 0.45), respectively. Individual parameters like a mean peripheral arterial haemoglobin saturation (SpO2) below 93% and percentage time spent below SpO2 93% correlated poorly with the consensus interpretations. Paediatric respiratory specialists instead relied on visual analysis of SpO2 waveforms, utilising the frequency and depth of desaturations to guide management. Conclusion Interpretation of overnight oximetry data is variable amongst both paediatric clinicians and respiratory specialists. This likely reflects inadequate evidence defining clinically significant intermittent hypoxaemia, whether in terms of desaturation duration, frequency or nadir.

“…Central events also included the periods with Cheyne-Stokes respiration, which were defined as at least three consecutive cycles of respiration with crescendo-decrescendo pattern interrupted by central hypopnea or apnea. The level of severity was expressed using the respiratory event index (REI) – the number of hypopneas and apneas/registration hours [4, 5]. Depending on the REI values (< 15/h and ≥15/h), the patients were divided into two groups to evaluate the influence of SA on Holter-ABPM parameters.…”

The Influence of Sleep Apnea on 24-Hour and Nocturnal ECG and Blood Pressure Parameters in Patients with Acute Heart Failure

et al. 2018

Objective: To investigate the influence of sleep apnea (SA) on ECG and blood pressure (BP) monitoring parameters in patients with acute heart failure (AHF). Methods: A total of 51 hospitalized patients with AHF (13 women, 38 men, mean age 60.8 years) underwent 24-hour combined monitoring of ECG and BP and SA testing before discharge. Heart rhythm (mean heart rate, arrhythmias, pauses, QT interval, heart rate variability) and BP (mean systolic and diastolic values, variability, circadian variation) parameters were obtained for the whole day and for nighttime (22: 00–06: 00). Depending on SA severity, the patients were divided into two groups (respiratory event index, REI, < 15/h and ≥15/h). Comparisons of parameters between the two groups were performed using t test and χ² test (alpha < 0.05 for significance). Results: A total of 29 (56.9%) patients had REI ≥15/h. In this group, the systolic and diastolic BP values (24-hour and nighttime) were significantly higher (p < 0.05). BP variability did not differ, and a markedly blunted circadian variation of both the systolic and diastolic values was observed. In the group with REI ≥15/h, we found a higher nocturnal versus diurnal mean heart rate ratio (p = 0.046) and a greater occurrence of nocturnal versus diurnal ventricular premature beats (p = 0.0098). Conclusion: The presence of significant SA was found to influence the BP values and nocturnal ventricular ectopy in patients with stabilized AHF. SA, 24-hour ECG, and BP monitoring could provide important information with potential impact on patient management.
