Inspiratory flow patterns with dry powder inhalers of low and medium flow resistance in patients with pulmonary arterial hypertension

Pulmonary Circulation, 2021
Inhalation profiles to support use of dry powder inhalers for drug delivery in patients with pulmonary arterial hypertension have not been reported. We aimed to evaluate the inspiratory flow pattern associated with low and medium flow resistance dry ...

Individual response in patient’s effort and driving pressure to variations in assistance during pressure support ventilation

Annals of Intensive Care, 2023
Background During Pressure Support Ventilation (PSV) an inspiratory hold allows to measure plateau pressure (Pplat), driving pressure (∆P), respiratory system compliance (Crs) and pressure-muscle-index (PMI), an index of inspiratory effort.

Effect of Inspiratory Muscle Training on Exercise Tolerance in Asthmatic Individuals [PDF]

, 2011
The aim of this study was to determine the effects of inspiratory muscle training (IMT) on exercise tolerance, inspiratory muscle fatigue, and the perception of dyspnea in asthmatic individuals. Using a matched double-blind placebo-controlled design, 15

Physiological effects of high-intensity versus low-intensity noninvasive positive pressure ventilation in patients with acute exacerbation of chronic obstructive pulmonary disease: a randomised controlled trial

Annals of Intensive Care, 2022
Background High-intensity noninvasive positive pressure ventilation (NPPV) is a novel ventilatory approach to maximally decreasing elevated arterial carbon dioxide tension (PaCO2) toward normocapnia with stepwise up-titration of pressure support.

Achieving Safe Liberation During Weaning from VV-ECMO in Patients with Severe ARDS: The role of Tidal Volume and Inspiratory Effort.

Chest, 2021
BACKGROUND Weaning from venovenous extracorporeal membrane oxygenation (VV-ECMO) is not well studied. VV-ECMO can be discontinued when patients tolerate non-injurious mechanical ventilation (MV) during a sweep gas off trial (SGOT). However, predictors of
