O R IG IN A L A R T IC L E INTRODUCTION Adequate postoperative analgesia is considered to be a major key for reducing pul monary morbidity and improving the outcome. Thoracic epidural anesthesia (TEA) has been proposed as a reliable analgesic method following thoracic surgery. Most of these benefi ts, however, relate to the postoperative or to the so-called perioperative period. Some case repor...

Aim. To compare respiratory mechanics and gas exchange in patients with acute distress syndrome (ARDS) without COVID-19. Material methods. We examined 96 patients, who were divided into two groups. The main group included 48 COVID-19-associated ARDS. control ARDS not associated Most characteristic selected for the following baseline parameters: age, sex, SAPS II score, disease severity, plateau...

We have studied the time course of changes in gas exchange and respiratory mechanics using two different modes of ventilation during 7 h of isoflurane anaesthesia in pigs. One group received conventional control mode ventilation (CV). The other group received biologically variable ventilation (BVV) which simulates the breath-to-breath variation in ventilatory frequency (f) that characterizes no...

Previous work investigating respiratory system mechanics in mice has reported an aging-related increase in compliance and mean linear intercept (Lm). However, these changes were assessed using only a young (2-mo-old) and old (20- and 26-mo-old) group yet were interpreted to reflect a linear evolution across the life span. Therefore, to investigate respiratory system mechanics and lung morphomet...

Interactive learning has been proven instrumental for the understanding of complex systems where the interaction of interdependent components is hard to envision. Due to the mechanical properties and mutual coupling of the lung and thorax, respiratory mechanics represent such a complex system, yet their understanding is essential for the diagnosis, prognosis, and treatment of various respirator...

Measurements of respiratory mechanics in mechanically-ventilated children are potentially useful for understanding the pathogenesis and progress of diseases resulting in respiratory failure. Measurement techniques that can be simply and noninvasively employed model the respiratory system as a single compartment. The frequency dependence of elastance and resistance, both of the total respiratory...
