Our results suggest that NPs may impair the rigidity sensing of cells even at low concentrations, thereby affecting cell adhesion and spreading. Our results suggest that NPs may impair the rigidity sensing of cells even at low concentrations, thereby affecting cell adhesion and spreading. Tidal expiratory flow limitation (EFL ) promotes intrinsic PEEP (PEEPi) in patients with chronic obstructive pulmonary disease (COPD). Applying non-invasive ventilation (NIV) with an expiratory positive airway pressure (EPAP) matching PEEPi improves gas exchange, reduces work of breathing and ineffective efforts. We aimed to evaluate the effects of a novel NIV mode that continuously adjusts EPAP to the minimum level that abolishes EFL . This prospective, cross-over, open-label study randomized patients to one night of fixed-EPAP and one night of EFL -abolishing-EPAP. The primary outcome was transcutaneous carbon dioxide pressure (PtcCO ). Secondary outcomes were peripheral oxygen saturation (SpO ), frequency of ineffective efforts, breathing patterns and oscillatory mechanics. We screened 36 patients and included 12 in the analysis (age 72 ± 8years, FEV1 38 ± 14%Pred). The median EPAP did not differ between the EFL -abolishing-EPAP and the fixed-EPAP night (median (IQR) = 7.0 (6.0, 8.8) cmH O during night vs 7.5 (6.5, 10.5) cmH O, p = 0.365). We found no differences in mean PtcCO (44.9 (41.6, 57.2) mmHg vs 54.5 (51.1, 59.0), p = 0.365), the percentage of night time with PtcCO  > 45mm Hg was lower (62(8,100)% vs 98(94,100)%, p = 0.031) and ineffective efforts were fewer (126(93,205) vs 261(205,351) events/hour, p = 0.003) during the EFL -abolishing-EPAP than during the fixed-EPAP night. We found no differences in oxygen saturation and lun
