Background: Weaning from mechanical ventilation in the intensive care unit is an important step in the treatment process. More patients in less than 6 hours after cardiac surgery can be separated from mechanical ventilation and extubated. However, 20-40% of patients after cardiac surgery, due to dysfunctional ventilator weaning response (DVWR), still remain under mechanical ventilation. Therefo...

ABSTRACT Otitis serous is a common disease in pediatrics and ENT which can be treated by various medical and surgical techniques. The traditional surgery treatment of this disease has been done by realation of middle ear cavity with myringotomy and insertion of ventilation tube in tympanic membrane. Since remaining time of ventilation tube in tympanic membrane has a direct effect on the tratm...
Background: The use of synchronized intermittent mandatory ventilation (SIMV) and pressure support ventilation (PSV) have been used for older children and adults. The purpose of this study was to compare PSV and SIMV modes in weaning from mechanical ventilation in neonate with respiratory failure. Methods: A randomized clinical trial study carried out in NICU ward of Valiasr hospital Imam Khom...
abstract background: different modes of mechanical ventilation are used for respiratory support after coronary artery bypass graft (cabg). this study aimed to compare the effect(s) of using adaptive support ventilation (asv) and synchronized intermittent mandatory ventilation (simv) on the length of mechanical ventilation (intubation duration) and hospital stay after coronary artery bypass graf...
variability of tidal volume and respiratory rate in normally breathing man has long been demonstrated [1]. however because of lack of knowledge and technology primary ventilators could only deliver a fixed tidal volume in a fixed rate the so called volume controlled ventilation (vcv). vcv was volume preset time triggered and cycled and there was no synchronization with patient’s breaths. at tha...
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...
