Effect of Continuous Positive Airway Pressure or Positional Therapy Compared to Control for Treatment of  Obstructive Sleep Apnea on the Development of Gestational Diabetes Mellitus in Pregnancy: Protocol for Feasibility Randomized Controlled Trial

Effect of Continuous Positive Airway Pressure or Positional Therapy Compared to Control for Treatment of Obstructive Sleep Apnea on the Development of Gestational Diabetes Mellitus in Pregnancy: Protocol for Feasibility Randomized Controlled Trial

During pregnancy, physiological changes, including upper airway edema and hormone-related upper airway pressure changes, predispose women to sleep-disordered breathing (SDB) [1]. The prevalence of obstructive sleep apnea (OSA) in pregnancy increases from 3.6% in early pregnancy to 8.3% in midpregnancy and is associated with an independent risk of gestational diabetes mellitus (GDM), preeclampsia, and hypertensive disorders of pregnancy (HDP) [2].

Diaphragmatic Breathing Interfaces to Promote Relaxation for Mitigating Insomnia: Pilot Study

Diaphragmatic Breathing Interfaces to Promote Relaxation for Mitigating Insomnia: Pilot Study

Research on breathing relaxation has often focused on enhancing breathing techniques and analyzing different breathing guidance designs. One study examined 3 types of breathing guidance designs, including voice-only guidance and 2 combinations of voice and visuals. The results showed that wave visualization designs outperformed voice-only designs in improving both objective breathing performance and user experience [7].

User Perceptions of Wearability of Knitted Sensor Garments for Long-Term Monitoring of Breathing Health: Thematic Analysis of Focus Groups and a Questionnaire Survey

User Perceptions of Wearability of Knitted Sensor Garments for Long-Term Monitoring of Breathing Health: Thematic Analysis of Focus Groups and a Questionnaire Survey

We developed a knitted breathing sensor garment [21,22] with a more classical look and feel that could potentially lead to wider user acceptance and market adoption, especially in areas related to long-term breathing monitoring. Long-term breathing monitoring has been identified as a method to help people with lung diseases such as asthma [23,24]. Exploring the preferences of users is an important ingredient in developing wearable sensor garments for long-term use [25].

Pulmonary and Physical Virtual Reality Exercises for Patients With Blunt Chest Trauma: Randomized Clinical Trial

Pulmonary and Physical Virtual Reality Exercises for Patients With Blunt Chest Trauma: Randomized Clinical Trial

Furthermore, physiotherapists play an important role in the prevention of complications, supporting patients with breathing and physical exercises. Breathing exercises are delivered by physiotherapists and address the active cycle of breathing technique and deep breathing [9,13]. Physical exercises mainly focus on maintaining and restoring the active range of motion of the trunk and limbs and restoring independence in functional activities [13].

Preliminary Assessment of an Ambulatory Device Dedicated to Upper Airway Muscle Training in Patients With Sleep Apnea: Proof-of-Concept Study

Preliminary Assessment of an Ambulatory Device Dedicated to Upper Airway Muscle Training in Patients With Sleep Apnea: Proof-of-Concept Study

For the breathing task, the participant is asked to continuously apply a small lip pressure of 4% of the maximal value. Visual feedback on the lip pressure is given to the user via a vertical bar. The participant is tasked with following a breathing pattern indicated on the screen. This task includes 7 breathing cycles, with 8 seconds for inhaling and 8 seconds for exhaling. The success of this task is defined by the fraction of the total time when the user has applied sufficient pressure.

Continuous Critical Respiratory Parameter Measurements Using a Single Low-Cost Relative Humidity Sensor: Evaluation Study

Continuous Critical Respiratory Parameter Measurements Using a Single Low-Cost Relative Humidity Sensor: Evaluation Study

Our device uses a relative humidity sensor (RHS) to detect breathing and calculate tidal volumes (TVs), expiratory reserve volumes (ERVs), and inspiratory reserve volumes (IRVs) [19]. To the best of our knowledge, the innovative aspects of this study are the direct measurement of respiratory cycles and the exact derivation of TD, ERV, IRV, and vital capacity (VC) data from the calculation of the breathing surface [16,20].
