Bench experiments comparing simulated inspiratory effort when breathing helium-oxygen mixtures to that during positive pressure support with air

BMC Pulmonary Medicine, 2012
Background Inhalation of helium-oxygen (He/O2) mixtures has been explored as a means to lower the work of breathing of patients with obstructive lung disease.

Effect of modified high-flow oxygen therapy on positive end-expiratory pressure and end-expiratory lung volume based on simulated lung platform

Heliyon, 2023
Objective: The aim of this study was to assess the effect of modified high-flow oxygen therapy on end-expiratory lung volume (EELV) and positive end-expiratory pressure (PEEP) in tracheotomized patients with normal pulmonary, acute hypoxic respiratory ...

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.

Model-Based Estimation of Inspiratory Effort Using Surface EMG

IEEE Transactions on Biomedical Engineering, 2023
The quantification of inspiratory patient effort in assisted mechanical ventilation is essential for the adjustment of ventilatory assistance and for assessing patient-ventilator interaction. The inspiratory effort is usually measured via the respiratory muscle pressure (P mus) derived from esophageal pressure (P es) measurements.

Identifying asynchronies: Ineffective effort

Journal of Mechanical Ventilation, 2022
Mechanical ventilation is a common issue in critically ill patients. It is a lifesaving treatment but also can cause some complications. Patient-ventilator asynchronies are frequent but are often underdiagnosed and they are a serious problem that is ...

Nurses' Detection of Ineffective Inspiratory Efforts During Mechanical Ventilation [PDF]

American Journal of Critical Care, 2012
BACKGROUND PATIENT: ventilator dyssynchrony is common and may influence patients' outcomes. Detection of such dyssynchronies relies on careful observation of patients and airway flow and pressure measurements. Given the shortage of specialists, critical care nurses could be trained to identify dyssynchronies.To evaluate the accuracy of specifically ...

Pendelluft in hypoxemic patients resuming spontaneous breathing: proportional modes versus pressure support ventilation

Annals of Intensive Care, 2023
Background Internal redistribution of gas, referred to as pendelluft, is a new potential mechanism of effort-dependent lung injury. Neurally-adjusted ventilatory assist (NAVA) and proportional assist ventilation (PAV +) follow the patient’s respiratory ...

Deficiency of Biogenic Amines Modulates the Activity of Hypoglossal Nerve in the Reserpine Model of Parkinson’s Disease

Cells, 2021
The underlying cause of respiratory impairments appearing in Parkinson’s disease (PD) is still far from being elucidated. To better understand the pathogenesis of respiratory disorders appearing in PD, we studied hypoglossal (HG) and phrenic (PHR ...

Helium-Oxygen in the Postextubation Period Decreases Inspiratory Effort

American Journal of Respiratory and Critical Care Medicine, 2001
Abstract After tracheal extubation, upper and total airway resistances may frequently be increased resulting in an increase in inspiratory effort to breathe. We tested whether breathing a helium-oxygen mixture (HeO2) would reduce inspiratory effort in the period after extubation.

Orthopnea and inspiratory effort in chronic heart failure patients

Respiratory Medicine, 2003
Orthopnea is a typical feature of patients with chronic heart failure (CHF), the factors contributing to it are not completely understood. We investigated changes in dyspnea and other respiratory variables, induced by altering posture (from sitting to supine) in 11 CHF patients (NYHA classes II-IV) and 10 control subjects.We measured dyspnea (Borg ...
