Effect of airway pressure on lumbar epidural pressure during positive pressure ventilation

Effect of airway pressure on lumbar epidural pressure during positive pressure ventilation

BACKGROUND The purpose of this study was to measure lumbar epidural pressure (EP) during the insertion of a Tuohy needle under general anesthesia and to evaluate the influence of airway pressure on EP. METHODS Lumbar EP was measured directly through a Tuohy needle during intermittent positive pressure ventilation in fifteen patients. Mean and peak EP were recorded after peak inspiratory press...

Bilevel Positive Airway Pressure Ventilation

Over the past few decades, invasive positive pressure ventilation, usually applied via an endotracheal tube, has been the standard treatment for acute respiratory failure [1–3]. However, intubation and mechanical ventilation is associated with significant morbidity, including upper airway trauma and infections [4–7]; indeed, it is the single most important predisposing factor for nosocomial pne...

Intraocular Pressure during Continuous Positive Airway Pressure

A 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)....

P32: Effect of Airway Pressure Release Ventilation Mode on Intracranial Pressure and Oxygenation in Patients with Traumatic Brain Injuries

This study aimed at compare influences of airway pressure release ventilation (APRV) and Synchronized Intermittent Mechanical Ventilation (SIMV) on intracranial pressure and oxygenation status in patients with traumatic brain injuries. A clinical trial was carried out in 40 patients with traumatic brain injuries in the intensive care unit in Kamyab neurosurgery Hospital, Mashhad, Iran. The pati...
