Assessment of excursion and thickness of diaphragm by ultrasound during acute exacerbation of chronic obstructive pulmonary disease and correlation with severity of airway obstruction

open access: yesJournal of Association of Pulmonologist of Tamil Nadu, 2023
Background: Diaphragm dysfunction in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) leads to increased morbidity and mortality. Early diagnosis of diaphragm dysfunction and aggressive management to improve the diaphragm function and

The influence of tensile forces on the deflection of circular diaphragms in pressure sensors [PDF]

open access: yes, 1984
It is known that the deflection of a diaphragm is determined by two mechanisms, bending moments or bending stress and tensile forces or membrane stress.\ud \ud Usually the influence of tensile forces is not taken into account when calculating the ...

Diaphragm recovery by laryngeal innervation after bilateral phrenicotomy or complete C2 spinal section in rats

open access: yesNeurobiology of Disease, 2006
This study aimed to highlight the functional aspects of diaphragm reinnervation by laryngeal motoneurons after bilateral phrenicotomy or complete cervical transection. The left recurrent laryngeal nerve was connected to the left phrenic nerve in 14 rats.

Blockage of the Ryanodine Receptor via Azumolene Does Not Prevent Mechanical Ventilation-Induced Diaphragm Atrophy. [PDF]

open access: yesPLoS ONE, 2016
Mechanical ventilation (MV) is a life-saving intervention for patients in respiratory failure. However, prolonged MV causes the rapid development of diaphragm muscle atrophy, and diaphragmatic weakness may contribute to difficult weaning from MV ...

Optimization Design of Diaphragm Profile based on Kriging Model

open access: yesJixie chuandong, 2022
The failures of diaphragm couplings in application are mostly originated from fatigue failures of the diaphragm. To improve the fatigue performance of the diaphragm coupling,a optimization design method for the diaphragm profile parameters based on the ...

Diaphragm function in patients with Covid-19-related acute respiratory distress syndrome on venovenous extracorporeal membrane oxygenation

open access: yesAnnals of Intensive Care, 2023
Background Venovenous extracorporeal membrane oxygenation (VV ECMO) is frequently associated with deep sedation and neuromuscular blockades, that may lead to diaphragm dysfunction.
