Positive airway pressure therapy and all-cause and cardiovascular mortality in people with obstructive sleep apnoea: a systematic review and meta-analysis of randomised controlled trials and confounder-adjusted, non-randomised controlled studies.

Background: Data regarding the effect of positive airway pressure (PAP) therapy for obstructive sleep apnoea (OSA) on all-cause mortality are inconsistent. We aimed to conduct a systematic review and meta-analysis to test the hypothesis that PAP therapy is associated with reduced all-cause and cardiovascular mortality in people with OSA.

Methods: For this systematic review and meta-analysis, we searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials, from database inception to Aug 22, 2023 (updated Sept 9, 2024), with no language or geographical restrictions.

Mild obstructive sleep apnoea in females: analysis of the MERGE randomised controlled trial.

Background: A analysis of the MERGE trial was conducted, to investigate whether sex differences are evident at the mildest end of the disease spectrum, for symptoms associated with obstructive sleep apnoea (OSA) and the response to continuous positive airway pressure (CPAP) treatment.

Methods: MERGE participants with mild OSA (apnoea-hypopnoea index 5-15 events·h; American Academy of Sleep Medicine 2012 criteria) were randomised to either CPAP plus standard care (sleep hygiene counselling) or standard care alone for 3 months. Quality of life (QoL) was measured by questionnaires completed before and after the 3 months.

Continuous positive airway pressure versus standard care for the treatment of people with mild obstructive sleep apnoea (MERGE): a multicentre, randomised controlled trial.

Background: The evidence base for the treatment of mild obstructive sleep apnoea is limited and definitions of disease severity vary. The MERGE trial investigated the clinical effectiveness of continuous positive airway pressure in patients with mild obstructive sleep apnoea.

Methods: MERGE, a multicentre, parallel, randomised controlled trial enrolled patients (≥18 years to ≤80 years) with mild obstructive sleep apnoea (apnoea-hypopnoea index [AHI] ≥5 to ≤15 events per h using either AASM 2007 or AASM 2012 scoring criteria) from 11 UK sleep centres.

Obstructive Sleep Apnea in Women: Specific Issues and Interventions.

Obstructive sleep apnea (OSA) has traditionally been seen as a male disease. However, the importance of OSA in women is increasingly being recognized, along with a number of significant gender-related differences in the symptoms, diagnosis, consequences, and treatment of OSA. Women tend to have less severe OSA than males, with a lower apnea-hypopnea index (AHI) and shorter apneas and hypopneas.

Impact of a New Nasal Pillows Mask on Patients' Acceptance, Compliance, and Willingness to Remain on CPAP Therapy.

Aim. Continuous positive airway pressure (CPAP) masks are a key factor in patient compliance. This program assessed the performance of a new nasal pillows mask (NPM) on a variety of new and established obstructive sleep apnea (OSA) patients using CPAP therapy.

Novel Approach to Simulate Sleep Apnea Patients for Evaluating Positive Pressure Therapy Devices.

Bench testing is a useful method to characterize the response of different automatic positive airway pressure (APAP) devices under well-controlled conditions. However, previous models did not consider the diversity of obstructive sleep apnea (OSA) patients' characteristics and phenotypes. The objective of this proof-of-concept study was to design a new bench test for realistically simulating an OSA patient's night, and to implement a one-night example of a typical female phenotype for comparing responses to several currently-available APAP devices.

Study of a Novel APAP Algorithm for the Treatment of Obstructive Sleep Apnea in Women.

Study Objectives: To assess the efficacy of a novel female-specific autotitrating continuous positive airway pressure (CPAP) algorithm (AutoSet for her, AfH) in premenopausal women relative to a standard autotitrating algorithm (AutoSet, S9) (ResMed Ltd., Bella Vista, New South Wales, Australia).

Design: Prospective randomised crossover noninferiority trial.

Evaluation of a new pediatric positive airway pressure mask.

Study Objectives: The choice and variety of pediatric masks for continuous positive airway pressure (CPAP) is limited in the US. Therefore, clinicians often prescribe modified adult masks. Until recently a mask for children aged < 7 years was not available.

Assessment of the performance of nasal pillows at high CPAP pressures.

Study Objectives: Compliance with CPAP therapy remains an issue despite its effectiveness. Mask selection is likely to affect a patients experience with CPAP, and multiple mask options are currently available. Nasal pillows have less contact with the face compared to nasal masks and may benefit patients by minimizing side effects; however, they are infrequently used at high CPAP pressures.

Assessment of the impact on compliance of a new CPAP system in obstructive sleep apnea.

Background: Despite the efficacy of continuous positive airway pressure (CPAP) for the treatment of obstructive sleep apnea (OSA), compliance with therapy remains suboptimal.The aim of this study was to determine whether the use of S9TM increased compliance in established CPAP users.

Methods: Subjects with OSA (50) were recruited into the study.
