Filter by:The principal aim is to assess impact of alveolar recruitment manoeuvres (ARM) on stroke volume variation, evaluated by trans-oesophageal echocardiography (TEE). These variations will be measured on preload dependency or preload independency status. The principal purpose is to determine if variations of stroke volume during standardized ARM can predict the preload dependency status.
To determine if a therapy regimen including treatment with The MetaNeb® System had a positive impact on the rate of pulmonary complications related to atelectasis and/or secretion retention that occur in high risk post-operative patients. This is a non-randomized facility (or hospital) level pre-post intervention study.
Investigators hypothesized that lung ultrasound-assisted recruitment maneuver would be beneficial in mechanically ventilated infants compared to those who did not receive lung ultrasound and alveolar recruitment maneuver.
Atelectasis is common during and after general anaesthesia and a number of interventions have been suggested in order to prevent their formation. The use of Positive End Expiratory Pressure (PEEP) during general anaesthesia has in recent years been questioned. The investigators hypothesize that the use of PEEP as a single intervention improves oxygenation and prevents atelectasis as investigated by computed tomography compared to a control group with zero PEEP.
This study evaluates the influence of alveolar recruitment maneuver, protocolized liberation from respiratory support and monitoring of Integrated Pulmonary Index on the duration of the mechanical ventilation and the number of pulmonary complications in the early postoperative period after cardiac surgery.
With an efficient epidural analgesia the physiological effects of pain are disabled during labor. Pain may cause an increase of minute volume, oxygen consumption and a decrease of paCO2 (Arterial CO2 pressure). The study will evaluate the lung function before and after labor with and without epidural analgesia. With more efficient breathing, the occurence of atelectasis should be reduced; this effect will be investigated in these settings for the first time with the electrical impedance tomography, which is a completely non-invasive measure.
The aim of this study is to find out relationship between PaO2/FiO2 and atelectasis finding on intraoperative lung ultrasound.
This study is designed to compare three ultrasound-based aeration scores that were previously validated in specific populations, and to assess their correlation with computed tomographic measurement of pulmonary aeration in a population with different pathologies. Hypothesis: The "Loss of Aeration Score" will be more accurate than a simplified version and another widely used score, the "Lung Ultrasound Score".
Lung ultrasound offers a novel, reliable and radiation-free tool for diagnosing perioperative atelectasis and evaluating its severity in adult patients undergoing general anesthesia in the operating room.
The aim of this study is to evaluate the effects of the use of breathing exercises with inspiratory loading on respiratory muscle strength and endurance, lung volumes and capacities and thoracoabdominal mobility in patients after bariatric surgery. It is believed that the use of inspiratory load may mitigate the negative effects of surgical trauma on respiratory muscle dysfunction, preserving respiratory muscle strength, lung volumes and diaphragm mobility, thus reducing the risk of pulmonary complications in the postoperative period.
