The pediatric mechanical ventilation in Canada (PeMViC) study: A Delphi survey of pediatric mechanical ventilation practices by Canadian respiratory therapists
The gap in knowledge for pediatric mechanical ventilation (MV) management makes practice standardization difficult. The European Society for Pediatric and Neonatal Intensive Care (ESPNIC) was the first to establish consensus recommendations on pediatric MV management. In Canada, respiratory …

On the Interaction of Natural Convection and Mechanical Ventilation
… the interaction of natural convection and mechanical ventilation in an enclosure where fluid is supplied at a low level and extracted at a high level. A turbulent buoyant plume rising from a localised source of buoyancy interacts with this upward ventilation flow to establish a steady-state …

Intensive care patients' perceptions of the experience of mechanical ventilation
… care patients' perceptions of the experience of mechanical ventilation. A purposeful sample of 11 post-extubation mechanically ventilated patients was interviewed using a semi-structured interview guide, and the interviews were audiotaped and transcribed. Data were analyzed for common themes and …

A Patient-Specific Multiscale Model of Mechanical Ventilation of COVID-19-afflicted Lungs
… Severe cases of COVID-19 are often treated with mechanical ventilation, which has a high risk of causing ventilator-induced lung injury. However, COVID-19 is a relatively recent disease, and there is a lack of detailed understanding of its response to mechanical ventilation. This thesis aims to …

Factors related to successful weaning from mechanical ventilation in endo-tracheal intubation patients
… factors related to successful weaning from mechanical ventilation. The 54 subjects selected from medical intensive care unit at one hospital in Suwon city were experienced the planned extubation by medical team. They were able to communicate without any restriction. This study obtained …

The effects of mechanical ventilation on the development of Acute Respiratory Distress Syndrome
… of respiratory failure have been treated using mechanical ventilation to help maintain gas exchange in the lungs. However, clinical investigators are beginning to discover the adverse effects of mechanical ventilation if it is not applied properly. Specifically, excessive ventilator volumes and …

The effects of prolonged mechanical ventilation on the alpha-adrenergic responses of costal diaphragm arterioles
Introduction: Mechanical ventilation (MV) is a life-saving intervention employed in Intensive Care Units worldwide. Previous work has shown a substantial time-dependent reduction in diaphragmatic blood flow and O₂ delivery with MV, likely contributing to diaphragm fatigue and weaning difficulties. …

Outcomes of patients with COVID-19 Acute Respiratory Distress Syndrome requiring Invasive Mechanical Ventilation admitted to an Intensive Care Unit in South Africa
… COVID-19 pneumonia may require ICU admission or mechanical ventilation [Guan et al., 2020; Huang et al., 2020]. Data from low- and middle-income countries for COVID-19 ARDS are limited. Groote Schuur Hospital in Cape Town, South Africa expanded its ICU service to support patients with COVID-19 …

High flow nasal oxygen versus mechanical ventilation as initial respirator support in severe COVID-19 ARDS at Groote Schuur Hospital : a propensity score analysis
… high flow nasal oxygen (HFNO), a novel ventilation strategy, was implemented as an alternative to mechanical ventilation (MV) at Groote Schuur Hospital in Cape Town, South Africa, during the first COVID wave. Patient received MV if HFNO failed. The purpose of this study was to compare …

Risk factors for prolonged ventilation in patients with chronic obstructive pulmonary disease presenting with acute respiratory failure
… respiratory failure often require invasive mechanical ventilation and subsequent admission to the intensive care unit (ICU). These patients are at an increased risk of prolonged and complicated ventilation and often experience weaning difficulties. In addition, the impact of a previous …

Early sequelae of post COVID-19 lung disease in patients who were mechanically ventilated for severe COVID-19 pneumonia
… (ARDS). Survival rates for patients requiring mechanical ventilation in Cape Town during the waves driven by the ancestral strain and beta variant were approximately 30% during the first 3 waves of the pandemic. However, post-ICU admission sequelae and recovery trajectory in sub-Saharan Africa …

RAC1-Mediated Actin Cytoskeleton Remodeling and Monolayer Barrier Properties of Stretched Alveolar Epithelial Cells
Mechanical ventilation is vital for supporting patients with pulmonary insufficiency. However, experimental data suggests that pulmonary injury can occur during mechanical ventilation as a result of elevated regional lung volumes resulting in excessive alveolar epithelial cell (AEC) stretch due to …
