Introduction: Patients that started on Non-Invasive Ventilation (NIV) need to define several parameters selected on the basis of diurnal arterial blood gas and underlying disease. We hypothesize that respiratory polygraphy (RP) could be useful to monitor NIV. This retrospective work describes RP findings and their impact on the setting of continuous flow ventilators from patients on NIV of Intensive Care Unit (ICU).
Material And Methods: Patient's data on NIV from at the ICU of Hospital Británico were included in this study. RP recordings were performed in all of them. Respiratory events, such as ventilatory pattern changes, impact on oximetry or tidal volume, were observed to modify the ventilatory mode after RP.
Results: The RP findings have contributes to change the ventilatory mode for one third of the patients. The mean values of expiratory positive airway pressure (EPAP) and inspiratory positive airway pressure (IPAP) were not significantly different across all the population before or after RP: 8.7±0.3 vs. 8.6±0.4; p<0.88 and 18.6±0.6 vs. 17.7±0.7; p<0.26 respectively, however, half the patients presented > 2 cmHO pressure value changes after RP.
Conclusions: RP recordings could contribute to broad range of data useful to make decisions about changes in programming and allowed to identify adverse events related to positive pressure.

Prevalence of Obstructive Sleep Apnea in Vietnamese Children with Attention Deficit Hyperactivity Disorder (ADHD).

Introduction: Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder among children with attention deficit hyperactivity disorder (ADHD). This study aims to determine the prevalence of OSA in children with ADHD, compare the differences in clinical characteristics between children with ADHD-OSA and those without OSA (ADHD-nonOSA), and to identify the correlation between OSA and ADHD in children.
Methods: This cross-sectional descriptive study was conducted on 524 children with ADHD, aged 6-12 years, at the Vietnam National Children's Hospital from October 2022 to September 2023.

Catathrenia is an uncommon sleep disorder. Having been originally classified as a parasomnia it is now considered a sleep related breathing disorder. Polysomnography (PSG) is the gold standard for diagnosing catathrenia which demonstrates a classic pattern of a deep inhalation followed by a protracted exhalation, accompanied by groaning sounds.

The current document represents the official position of Associação Brasileira do Sono (ABS; Brazilian Sleep Association) on the application of different sleep studies and provides specific recommendations for the use of different types of polysomnography (PSG) and respiratory polygraphy. The present document was based on existing guidelines. The steering committee discussed its findings and developed recommendations and contraindications, which were refined in discussions with the advisory committee.

: Respiratory rate (RR) is a clinical measure of breathing frequency, a vital metric for clinical assessment. However, the recording and documentation of RR are considered to be extremely poor due to the limitations of the current approaches to measuring RR, including capnography and manual counting. We conducted a validation of the automatic RR measurement capability of AcuPebble RE100 (Acurable, London, UK) against a gold-standard capnography system and a type-III cardiorespiratory polygraphy system in two independent prospective and retrospective studies.

Article Synopsis
- Obstructive sleep apnea (OSA) mainly affects obese patients and can lead to serious organ damage, with less understood consequences for bone health related to fat distribution.
- In a study of 49 patients with mild-to-severe OSA, it was found that 63% had increased visceral adipose tissue (iVAT), which correlated with higher rates of hypertension and diabetes, as well as worse nocturnal oxygen levels.
- Patients with iVAT displayed significantly lower lumbar spine trabecular bone scores compared to those with normal visceral fat, indicating a negative impact of VAT on bone quality, which could also link to vertebral fractures.
