Providing a fresh and cool airflow in underground mines is one of the main concerns during mining. Destruction of support systems, the presence of undesirable objects in the airway and distortion of airflow are the parameters involved that would result in pressure loss, which would affect the ventilation network. There are a lot of research works about the ventilation network planning that cons...

Indoor air quality (IAQ) influences the health of humans, the young and the old being generally more susceptible. In this study we examined how supply and demand of indoor air quality in dwellings are matched. On the supply-side, we evaluated ventilation systems, including natural ventilation, balanced ventilation, and adaptive systems. Two major healthrelated aspects are flexibility (both a se...

STUDY OBJECTIVE To evaluate a new method of closed-loop mechanical ventilation using an adaptive lung ventilation (ALV) controller in patients with different pathologic causes of respiratory failure at a time when they first met standard weaning criteria. STUDY DESIGN Prospective, open, selected case study. SETTING The 10-bed, multidisciplinary respiratory intensive care unit at Groote Schu...

INTRODUCTION: There are a lot of clinical trials about benefits closed-loop ventilation modes, which able to automatically adjust certain respiratory settings. These studies describe safety, reliability and advantages intellectual modes over conventional modes. OBJECTIVE: To assess awareness Russian intensive care practitioners closed loop availability these in routine practice. The second aim ...

Background: Postoperative pulmonary complications (PPC) are of the major reasons for death. Prolonged mechanical ventilation (PMV) and delayed extubation are leading to the incidence of more seriously complications. The effect of hyperinflation has not been investigated in control of these complications in patients who have been weaned from mechanical ventilation and are undergoing T-tube suppo...

Preterm infants (PIs) often require respiratory support due to surfactant deficiency. Early weaning from mechanical ventilation to noninvasive respiratory support decreases ventilation-associated irreversible lung damage. This wean is particularly challenging in PIs with cleft lip and cleft palate due to anatomical difficulties encountered in maintaining an adequate seal for positive pressure v...

introduction: tuberculosis (tb), with different types of respiratory tract involvements, has a high rate of mortality all around the world. endobronchial involvement, which is a slightly common tuberculous infection, requires special attention due to its severe complications such as bronchostenosis. aim of study of this study was describes, one type of pulmonary tuberculosis with less diagnosed...

OBJECTIVE To evaluate the relationship between duration of mechanical ventilation before the initiation of extracorporeal life support and the survival rate in children with respiratory failure. Extracorporeal life support has been used as a rescue therapy for >30 yrs in children with severe respiratory failure. Previous studies suggest patients who received >7-10 days of mechanical ventilation...

Background: Early nasal continuous positive airway pressure (NCPAP) has emerged as a primary modality of respiratory support for preterm infants withrespiratory distress syndrome (RDS). However, 30%-40% of these newborns need subsequent mechanical ventilation. Nasal intermittent positive pressure ventilation (NIPPV) is a promising alternative to NCPAP, especially in po...
