Filter by:Perioperative changes in regional ventilation by pulmonary electrical impedance tomography and spirometry will be investigated in patients at risk for postoperative pulmonary complications. Those patients undergo lung and flail chest surgery.
The objective of the study is to estimate the incidence of asynchrony and to assess its relationship with respiratory mechanics. This will be a prospective cohort study, including patients under invasive mechanical ventilation. Within 48h post intubation, the investigators will record the values of intrinsic positive end-expiratory pressure, pulmonary compliance and resistance. Participants will be followed up from intubation to mechanical ventilation liberation. The investigators will register clinical signs of asynchrony and record ventilator waveforms continuously and quantify patient-ventilator asynchrony. The investigators will calculate the total asynchrony index (AI) and of each asynchrony type (ineffective triggering, double triggering, auto triggering, short cycling and prolonged cycling). Participants will be followed up until hospital discharge.
Patients with chronic respiratory failure such as those associated with Chronic Obstructive Pulmonary Disease (COPD), Obesity Hypoventilation Syndrome (OHS), Obstructive Sleep Apnea (OSA) or Neuromuscular Disease (NMD) are increasingly managed with domiciliary non-invasive positive pressure ventilation (NIPPV). The aim of this study is to now compare the Automatic Expiratory Positive Airway Pressure (AutoEPAP) algorithm with a fixed manual EPAP in iVAPS mode on an Astral mixed mode ventilator. It is proposed that the automatic settings of AutoEPAP will be as effective at managing respiratory failure and upper airway obstruction (UAO) as manual EPAP on the Astral device. Specifically demonstrating that the AutoEPAP function is as effective at treating UAO as manual EPAP.
With the increasing aging population demographics and life expectancies, the number of very elderly patients undergoing surgery is rising. Elderly patients constitute an increasingly large proportion of the high-risk surgical group. Cardiac complications and postoperative pulmonary complications are equally prevalent and contribute similarly to morbidity, mortality, and length of hospital stay. Specific optimization strategy of general anesthesia has been tested in high-risk patients undergoing major surgery to improve outcomes. Our hypothesis is that a combined optimization strategy of anesthesia concerning hemodynamic, ventilation, and depth of anesthesia may improve short- and long- term outcome in elderly undergoing high risk surgery.
The purpose of this prospective observational cohort study is to evaluate multimodal monitoring technologies in the perioperative care of cardiac surgical patients. Right ventricular pressure tracings, near infrared spectroscopy (NIRS) and transthoracic ultrasonography will be studied for their ability to detect and predict complications such as right ventricular failure, renal failure and respiratory failure.
The objective of this trial is to assess the safety and effectiveness of the Edwards Pericardial Aortic Bioprosthesis Model 11000A, in the pulmonary position in pediatric and adult subjects five years or older requiring replacement of their native or prosthetic pulmonary valve.
Nasal High Flow (NHF) and CPAP are established forms of respiratory support in neonates and often produce similar clinical outcomes. The aim of the study was to investigate airway pressure during NHF and CPAP in neonates.
This study evaluates the difference between Non Invasive Ventilation with Neurally Adjusted Ventilatory Assist (NIV-NAVA) and Conventional Non Invasive Ventilation with Pressure Support (PS) or Pressure Control (PC). All the patients are ventilated in each mode for 4 hours. Afterwards they will be subjected to a semi-structured interview where they will be asked to compare the two modes. The hypothesis is that NIV-NAVA will correct patients power of Hydrogen (pH), PaCO2 og PaO2 more quickly than NIV-PS and NIV-NAVA is more comfortable for the patients.
The purpose of this study is to evaluate the safety and short-term effectiveness of implantation of Transcatheter Pulmonary Valve (TPV) for the treatment of congenital heart disease with pulmonary valve disease.
The primary objective of this study is to evaluate the effect of early application of nasal high flow oxygen therapy after pulmonary lobectomy on the incidence of postoperative hypoxemia
