Active clinical trials for "Pulmonary Atelectasis"

Effects of the high frequent chest wall oscillation technique applied on the patients who were intubated in intensive care unit were investigated. A total of 30 patients who were intubated and under the mechanical ventilator supplied, were included in the study. While the control group (n=15) received routine pulmonary rehabilitation technique, the study group (n=15) was administered high frequency chest wall oscillation for 72 hours as 4 times of 15-minute intervals, in addition to the pulmonary rehabilitation technique. Patients 'APACHE-II scores, dry sputum weight, Lung Collapse Index and blood gas values were measured at the hours 24th, 48th and 72nd, and endotracheal aspirate culture was studied at initial and 72nd. In addition, patient outcomes were evaluated at the end of the first week.

The purpose of this study is to compare the effect of the autogenic drainage and the intrapulmonary percussive ventilation on the levying of the lung atelectasis, by means of the thoracic imaging (thoracic ultrasound and radiography), at the intubated or extubated child with the ventilatory support.

This study aims to compared the effects in driving pressure of an open-lung strategy with a positive end-expiratory pressure (PEEP) titrated to best driving pressure (DP) after a RM versus the recommended protective PEEP of 5 cmH2O without a recruitment manuever in non-obese patients undergoing cardiac surgery.

To evaluate the use of Incentive Spirometry in Non-critically Ill Hospitalized Patients With Shortness of Breath.

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.

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 aim of this study is to find out relationship between PaO2/FiO2 and atelectasis finding on intraoperative lung ultrasound.

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.

Morbid obese patients present changes in respiratory physiology caused by weight overload. Intraoperative atelectasis is a pulmonary complication that affects not only gas exchange but also respiratory mechanics. The present study was aimed to test the role of different parameters for monitoring the treatment of atelectasis by a lung recruitment maneuver.

HYPOTHESIS: During anesthetic pre-oxygenation with high FiO2, pulmonary atelectasis occur, especially in patients < 6 years old, where FRC and pulmonary closing volume may overlap. New borns and children <1 year old are especially vulnerable. OBJECTIVES: Validate "air test" as a individualized and non-invasive diagnostic method of clinically significant atelectasis in pediatrics. Determine what other factors contribute to atelectasis development in pediatrics METHODS: 30 pediatric patients will be studied with ages ranged between 45 postconceptional weeks and16 years old. Baseline SpO2 and lung ultrasound will be performed for each patient upon arrival at the operating theatre before preoxygenation with FiO2 of 1.0 SpO2 will be measured 15 min after intubation during a 5 min long "air test" trial (FiO2 0.25). lung collapse will be verified by lung ultrasound at the end of the 15 min trial. Lung collapse will be eventually granted upon lung US verification by a blind researcher.
