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...

Aims. The aim of the study was to compare endotracheal intubation with i-gel and LMA (laryngeal mask airway) supreme supraglottic airway devices in orbital osteosynthesis surgery. Methods. 134 patients undergoing orbital plasty after fracture were enrolled in our study and were randomized into three groups: 43 in the endotracheal intubation group, 42 in the LMA-Supreme group, and 49 patients w...

BACKGROUND Airway pressure-release ventilation (APRV) is a novel mode of positive-pressure ventilation that has several advantages over low-tidal-volume, assist-control ventilation in patients with acute respiratory distress syndrome, specifically, lower airway pressures, lower minute ventilation, minimal effects on cardio-circulatory function, ability to spontaneously breathe throughout the en...

conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...

Acute respiratory distress syndrome (ARDS) results in collapse of alveoli and therefore poor oxygenation. In this article, we review airway pressure release ventilation (APRV), a mode of mechanical ventilation that may be useful when, owing to ARDS, areas of the lungs are collapsed and need to be reinflated ("recruited"), avoiding cyclic alveolar collapse and reopening.

STUDY OBJECTIVE To quantify the impact on peak airway pressure of pressure-controlled and volume-controlled ventilation during Laryngeal Mask Airway (LMA) use. DESIGN Prospective, crossover clinical study. SETTING University-affiliated hospital. PATIENTS 32 ASA physical status I and II patients undergoing general anesthesia with the LMA. INTERVENTIONS Patients were ventilated for three ...
