Regional ventilation distribution: effects of lateral posture and airway clearance techniques in healthy and individuals with COPD Open
This study provides the first direct evaluation of regional ventilation distribution during airway clearance techniques (ACTs) in the lateral posture using electrical impedance tomography. We show that the intended increase in dependent-lu…

Factors Influencing Nasal Irrigation Efficacy in Infants: An Exploratory <span>3D</span> Model Study Open
Background Nasal irrigation is widely practiced in infants, but its execution varies greatly. Although a consensus on how to perform this procedure has been published, supporting experimental evidence is lacking. In vitro investigations us…

Airway clearance techniques for people with acute exacerbation of COPD: a scoping review Open
Introduction Acute exacerbations of COPD (AECOPD) often involve mucus hypersecretion. Thus, management of sputum retention is critical. However, the use of airway clearance techniques (ACTs) in people with AECOPD across different healthcar…

Geometric validation of a pediatric upper airways model made using a mainstream desktop 3D printer Open
Background: Three-dimensional (3D) printing has become increasingly affordable. Several research projects used 3D printing to create in vitro upper airways model. However, studies using a mainstream desktop 3D printer never performed geome…

The Impact of Positive Expiratory Pressure Therapy on Hyperinflation in Patients With COPD Open
In patients with COPD, the effect of PEP therapy on lung hyperinflation is unclear owing to the non-consistent change in lung hyperinflation outcomes, insufficient data, and lack of high-quality trials. Dyspnea and physical capacity might …

Airway clearance techniques and exercise in people with bronchiectasis: two different coins Open
For people with bronchiectasis, achieving long-term adherence to physiotherapy strategies is a major challenge. The regular use of airway clearance techniques (ACTs) reduces the burden of sputum-related symptoms (e.g. increased expectorati…

European Respiratory Society statement on airway clearance techniques in adults with bronchiectasis Open
Airway clearance techniques (ACTs) are part of the main management strategy for patients with bronchiectasis. Despite being a priority for patients, accessibility, implementation and reporting of ACTs are variable in clinical settings and …

Effects of the Intermittent Intrapulmonary Deflation Technique on Expiratory Flow Limitation: an in Vitro Study Open
Introduction: The intermittent intrapulmonary deflation (IID) technique is a recent airway clearance technique that intends to delay the onset of expiratory flow limitation (EFL) during exhalation. We showed in a previous study that IID in…

Breathing Control Exercises Delivered in a Group Setting for Patients with Chronic Obstructive Pulmonary Disease: A Randomized Controlled Trial Open
Breathing control exercises are an important component of occupational therapy in patients with chronic obstructive pulmonary disease (COPD). Delivering these exercises in group settings may enhance their benefits. Therefore, this study as…

Short-Term Effect of Intermittent Intrapulmonary Deflation on Air Trapping in Patients With COPD Open
The RV decreased after intermittent intrapulmonary deflation compared with PEP, but this effect was not captured by other estimates of hyperinflation. Although the expiratory volume obtained during the VC maneuver with intermittent intrapu…

The effect of tongue elevation muscle training in patients with obstructive sleep apnea: A randomised controlled trial Open
Background Oropharyngeal myofunctional therapy is a multi‐component therapy effective to reduce the severity of obstructive sleep apnoea (OSA). However, existing protocols are difficult to replicate in the clinical setting. There is a need…

Effects of the intermittent intrapulmonary deflation technique on airway clearance in patients with cystic fibrosis Open
BACKGROUND: The intermittent intrapulmonary deflation (IID) technique is a new airway clearance strategy that produces a succession of very short air depressions in the bronchial tree. In patients with bronchial hypersecretion,the IID aims…

Consensus on Nasal Irrigation in Infants: A Delphi Study Open
Introduction: Nasal irrigation is regularly used in infants to relieve upper airway symptoms. However, because there is no consensus on good practice, nasal irrigation in infants is described and applied heterogeneously among clinicians an…
