Filter by:The purpose of the study is to evaluate the safety and effectiveness of the PULSTA Transcatheter Pulmonary Valve (TPV) System for the treatment of congenital or acquired pulmonary valve stenosis and/or regurgitation who require pulmonary valve replacement.
Optical guidance for percutaneous tracheostomy in intensive care is usually performed by conventional multi use bronchoscopy. Recently a single use bronchoscope has been introduced that allows for endotracheal visualization. For feasibility evaluation, 23 patients in intensive care receive percutaneous tracheostomy with optical guidance by the Ambu® aScopeTM 4 bronchoscope and 23 patients in intensive care receive percutaneous tracheostomy with a conventional bronchoscope (Olympus BF Type P60). The primary end point is the visualization through the single use bronchoscope of endotracheal landmark structures for tracheostomy and visualization of the needle insertion (according to score, see detailed description).
Pulmonary Disorders are often categorized as Obstructive or Restrictive disorders. This study will establish two channels of investigation, one group within each type of pulmonary dysfunction. State-of-the-Art Objective analytics will be employed to track patients from baseline and 6 month intervals for up to one year. Chronic Obstructive Pulmonary Disease (COPD) is a lung-related disorder that is characterized by long-term, often progressive state of poor airflow. Primary symptoms include low oxygen tension, shortness of breath, productive cough, and broncho-pulmonary inflammation and interference with oxygen-carbon dioxide exchange. COPD is generally considered those who are able to better inspire air than to expel. Restrictive lung dysfunctions are generally considered those who are unable to achieve full inspiration function. Both can create some of the same symptoms, low Oxygen exchange, activity intolerance of exertion, shortness of breath (SOB), Pulmonary Hypertension, Loss of lung structure, Pneumothorax (in emphysema), may mandate supplemental Oxygen therapy, failure of airway mucus management (chronic bronchitis, bronchiectasis, etc), and other failure of lung function issues. Restrictive lung disorders represent a group of pulmonary function losses which are due to acquired fibrosis, congenital fibrotic disorders, functional airway damage (scarring), vascular abnormalities in arterial/venous supply, Air pollution and tobacco smoking, chemical inhalation damage, etc. are felt to be common contributor of these issues. Diagnostic testing is based on poor airflow measured by lung function studies and whose symptoms do not improve much with anti-asthma bronchodilators, steroids, and a variety of combination of topical medications. Study is an interventional study to document the safety and efficacy of use of cSVF in chronic broncho-pulmonary disease within both groups.
The pilot/feasibility study evaluates the ability of High Velocity Nasal Insufflation (HVNI) therapy to facilitate ambulation and mobilization in patients experiencing shortness of breath, as compared to simple oxygen therapy.
Premature infants often receive respiratory support and supplemental oxygen for a prolonged period of time during their admission in the NICU. While maintaining the oxygen saturation within a narrow target range is important to prevent morbidity, manual oxygen titration can be very challenging. Automatic titration by a controller has been proven to be more effective. However, to date the performance of different controllers has not been compared. The proposed randomized crossover trial Comparing Oxygen Controllers in Preterm InfanTs (COCkPIT) is designed to compare the effect on time spent within target range. The results of this trial will help determining which algorithm is most successful in controlling oxygen, improve future developments in automated oxygen control and ultimately reduce the morbidity associated with hypoxemia and hyperoxemia.
Objective: To evaluate the effectiveness of two protocols of inspiratory muscle training (IMT) in older women to improve respiratory strength, spirometric parameters and dyspnea. Low-intensity vs high-intensity resistance training programs. Evaluations: Determination of the maximum inspiratory pressure (MIP) and the maximum expiratory pressure (MEP); spirometry - maximum voluntary ventilation (MVV), peak expiratory flow (PEF), tidal volume (TV); functional capacity measured with 6 minute walk test; dyspnea using the Borg scale and clinical evaluations. The participants will be evaluated at the beginning and end of the intervention period. Intervention: There are two groups of patients, one works with low loads (20% MIP) and another with high loads (40% MIP). They train 5 days/week 15 cycles lasting 1 minute. There is a rest of 1 minute between each cycle.
Nutritional status in critically ill pediatric patients is considered a fundamental prognostic factor in terms of mortality, morbidity, complications and outcome. Many studies report how predictive equations most commonly applied are inaccurate, therefore under or over estimating the body energy requirements. For this reason, actual measurement of resting energy expenditure (REE) through indirect calorimetry (IC) is considered to be a better approach. Currently, IC is not validated during the use of non-invasive ventilation. Aim of the present study is to validate the measurement of REE with IC in pediatric patients undergoing non-invasive ventilation through a single-limb circuit with intentional leak.
This study aims to examine the tolerance, feasibility, and physiological effects in airway clearance by using a novel non-invasive oscillating transducer device (NIOD, FrequencerTM) in critically ill children. The project is two years long with two separate stages of investigation. This study specifically examines different frequencies of NIOD to find the best frequency on patients outcomes.
The plethysmographic variation index (PVi) is a measure of the respiratory-induced variations in the plethysmographic waveform. Interestingly, in mechanically ventilated patients and under certain conditions, PVi may reflect fluid responsiveness (FR). Patients treated with high flow nasal cannula (HFNC), which has been described as a useful supportive therapy in spontaneously breathing patients with respiratory failure, may present the same hemodynamic changes, measured by transthoracic echocardiography, as those patients who are mechanically ventilated (MV). The hypothesis of the present study is that the PVi may predict FR in HFNC patients and, therefore, the objective is to investigate whether the PVi can predict FR in patients treated with HFNC.
To compare the duration of mechanical ventilation and the weaning period between two groups of patients managed with either Standard Care or with mechanical ventilation adjusted according to the Beacon Caresystem, in patients receiving mechanical ventilation for more than 24 hours
