Being more positive about negative ventilation?
Mechanical ventilation is undoubtedly a lifesaving procedure for patients with acute respiratory failure [1]. Unfortunately the procedure is also associated with a number of unwanted side-effects. Firstly, until recently, mechanical ventilation required endotracheal intubation either through a tracheostomy or with a translaryngeal tube, procedures which can carry some risks [2, 3]. Secondly, by...
متن کاملNegative- versus positive-pressure ventilation in intubated patients with acute respiratory distress syndrome
INTRODUCTION Recent experimental data suggest that continuous external negative-pressure ventilation (CENPV) results in better oxygenation and less lung injury than continuous positive-pressure ventilation (CPPV). The effects of CENPV on patients with acute respiratory distress syndrome (ARDS) remain unknown. METHODS We compared 2 h CENPV in a tankrespirator ("iron lung") with 2 h CPPV. The s...
متن کاملA Comparison between Nasal Intermittent Positive Pressure Ventilation and Nasal Continuous Positive Airway Pressure Ventilation in the Treatment of Neonatal Respiratory Distress Syndrome
Background: Nasal intermittent positive pressure ventilation (NIPPV) is a non-invasive ventilatory mode, which delivers mechanical ventilation via nasal tubes or prongs. The present study was conducted to compare the efficacy of NIPPV and nasal continuous positive airway pressure ventilation (NCPAP) in reducing the need for intubation in preterm infants with respiratory distress syndrome (RDS)....
متن کاملThe relationship between body image and social anxiety with positive and negative affect in the over- weight women
Obesity and overweighting as a chronic disorder are effected from the complex interaction of environmental, cultural, psychosocial, metabolic, and genetically factors and cause an emotional, psychological, and social problem for peoples. The current research aimed to determine the relationship between body image and social anxiety with positive and negative affect in overweight women. A descrip...
متن کاملconstruction of vector fields with positive lyapunov exponents
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
