1. When is non-invasive ventilation indicated? There is strong evidence that non-invasive ventilation should be used for the initial management of acute respiratory failure in patients with exacerbated COPD, acute pulmonary edema, disorders with concomitant immunosuppression as well as to facilitate extubation in patients with COPD who have failed weaning attempts[1]. In postoperative patients,...

INTRODUCTION High frequency percussive ventilation is a ventilatory technique that delivers small bursts of high flow respiratory gas into the lungs at high rates. It is classified as a pneumatically powered, pressure-regulated, time-cycled, high-frequency flow interrupter modality of ventilation. High frequency percussive ventilation improves the arterial partial pressure of oxygen with the sa...

Dynamic Chest Image Analysis aims to develop model-based computer analysis and visualization methods for showing focal and general abnormalities of lung ventilation and perfusion based on a sequence of digital chest fluoroscopy frames collected with the Dynamic Pulmonary Imaging technique [18,5,17,6]. We have proposed and evaluated a multiresolutional method with an explicit ventilation model b...

OBJECTIVE To investigate the role of hemocoagulase to prevent pulmonary hemorrhage in critical newborns on mechanical ventilation. DESIGN Randomized controlled trial. SETTING Neonatal Intensive Care Unit of an affiliated hospital of a Medical University. CHILDREN Seventy-two critical newborn infants on mechanical ventilation. INTERVENTION The involved neonates were divided randomly into...

Comparison of the Effect Cydonia oblonga and Phyllanthus Emblica on Gastric Residual Volume Pulmonary Aspiration in Patients under Mechanical Ventilation Mousavi Hospital ICU Zanjan 2020

Non-invasive mechanical ventilation has been increasingly used to avoid or serve as an alternative to intubation. Compared with medical therapy, and in some instances with invasive mechanical ventilation, it improves survival and reduces complications in selected patients with acute respiratory failure. The main indications are exacerbation of chronic obstructive pulmonary disease, cardiogenic ...

Chronic unilateral pulmonary artery ligation induces formation of new bronchial collateral vessels in the affected lung. These vessels form precapillary anastomoses with the pulmonary circulation and the lung is perfused with arterial blood. Inspired gas is diverted to the contralateral lung to maintain the ventilation/perfusion ratio (VA/Q) and gas exchange. This study was designed to determin...

C hronic thromboembolic pulmonary hypertension (CTEPH) is the result of chronic obstruction of the pulmonary arteries by thrombi which ultimately leads to right heart failure and death. Pulmonary thromboendarterectomy (PTE) has emerged as a standard therapeutic approach. Reperfusion lung oedema (RLE), which presents as acute deteriorating oxygenation and postoperative pulmonary hypertension, is...

BACKGROUND Even protective ventilation may aggravate or induce lung failure, particularly in preinjured lungs. Thus, new adjuvant pharmacologic strategies are needed to minimize ventilator-induced lung injury (VILI). Intermedin/Adrenomedullin-2 (IMD) stabilized pulmonary endothelial barrier function in vitro. We hypothesized that IMD may attenuate VILI-associated lung permeability in vivo. ME...
