DOI: 10.1016/j.chest.2021.08.078
Abstract: BACKGROUND Expiratory muscle weakness and impaired airway clearance are early signs of respiratory dysfunction in Duchenne muscular dystrophy (DMD), a degenerative muscle disorder in which muscle cells are damaged and replaced by fibrofatty tissue. Little… read more here.

DOI: 10.1097/aln.0000000000004631
Abstract: BACKGROUND Superobesity and laparoscopic surgery promote negative end-expiratory transpulmonary pressure, which causes atelectasis formation and impaired respiratory mechanics. We hypothesized that end-expiratory transpulmonary pressure differs between fixed and individualized PEEP strategies, and mediates their effects… read more here.

DOI: 10.1113/ep089365
Abstract: Cardio‐ventilatory coupling refers to the onset of inspiration occurring at a preferential latency following the last heartbeat (HB) in expiration. According to the cardiac‐trigger hypothesis, the pulse pressure initiates an inspiration via baroreceptor activation. However,… read more here.

DOI: 10.1152/japplphysiol.00059.2020
Abstract: Tidal expiratory flow limitation (EFL), which may herald airway closure (AC), is a mechanism of loss of aeration in ARDS. In this prospective, short-term, 2-center, study we measured static and dynamic chest wall (Est,cw and… read more here.

DOI: 10.1152/physiol.2023.38.s1.5728569
Abstract: Introduction: Tidal expiratory flow limitation (EFLT) occurs when the tidal breath reaches its maximal capacity to generate flow despite increased expiratory effort. It has been suggested there are gender differences; females tend to develop EFLT… read more here.

DOI: 10.1183/13993003.02234-2019
Abstract: Background The optimal noninvasive application of external positive end-expiratory pressure (EPAP) to abolish tidal-breathing expiratory flow limitation (EFLT) and minimise intrinsic positive end-expiratory pressure (PEEPi) is challenging in COPD patients. We investigated whether auto-titrating EPAP,… read more here.
