Filter by: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.
Aim of this study is to better understand pathophysiology of the alteration of respiratory mechanics and cardiovascular function in obese volunteer subjects. The investigators plan to test this hypothesis with a physiological, interventional study conducted on volunteers by using Electrical Impedance Tomography in a group of patients and magnetic resonance imaging (MRI) in another group.
The goal of this interventional crossover study in morbidly obese intubated and mechanically ventilated patients is to describe the respiratory mechanics and the heart-lung interaction at titrated positive end-expiratory pressure levels following a recruitment maneuver with transthoracic echocardiography and electric impedance tomography imaging.
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".
This study evaluates the omission of incentive spirometry use following bariatric surgery. Half of participants will receive an incentive spirometer while the other half will not. Oxygen saturation and pulmonary complications after surgery will be measured to examine the effectiveness of incentive spirometry.
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.
