conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...

background: application noninvasive ventilation in the patients with exacerbation of chronic obstructive pulmonary disease (copd) reduced mortality. this case-control study was designed to compare efficiency and outcome of non-invasive (niv) versus invasive positive pressure ventilation (ippv) in respiratory failure due to copd methods: the patients were assigned to niv or ippv intermittantly.t...

lung contusion is an entity involving injury to the alveolar capillaries, without any tear or cut in the lung tissue. this results in accumulation of blood and other fluids within the lung tissue. the excess fluid interferes with gas exchange leading to hypoxia. the pathophysiology of lung contusion includes ventilation/perfusion mismatching, increased intrapulmonary shunting, increased lung wa...

introduction chronic obstructive pulmonary disease (copd) is a chronic disorder with many systematic complications and one of the most important reasons for patients to require mechanical ventilation, admission in intensive care unit and prolonged mechanical ventilation. although the first attempt in separation of mechanical ventilation is failed in half of chronic obstructive pulmonary disease...

introduction underdevelopment of the lung parenchyma associated with abnormal growth of pulmonary vasculature in neonates with congenital diaphragmatic hernia results in pulmonary hypertension which mandates smooth elective mechanical ventilation in postoperative period, for proper alveolar recruitment and oxygenation, allowing lungs to mature enough for its functional anatomy and physiology. d...

administration of endotracheal surfactant is potentially the main treatment for neonates suffering from rds (respiratory distress syndrome), which is followed by mechanical ventilation. late and severe complications may develop as a consequence of using mechanical ventilation. in this study, conventional methods for treatment of rds are compared with surfactant administration, use of mechanical...
