Active clinical trials for "Hypoventilation"

In endotracheal intubation, it is essential that the trachea is intubated and not the esophagus. In suboptimal situations (outside an operating theatre), malpositioning of the endotracheal tube occurs frequently and is often fatal. The diagnostic tools that are available in the operating theatre are not appropriate for out-of-hospital situations because of several reasons. Moreover, these methods mostly take some time to provide the desired information and don't have optimal specificity and sensitivity. In order to allow fast diagnosis of this potentially fatal complication, we have developed a fully-automatic detection device to diagnose endotracheal tube malpositioning within 2 seconds. A high sensitivity/specificity of the algorithm for waveform-analysis was demonstrated in healthy patients and patients with pulmonary diseases (decreased pulmonary compliance). A new stand-alone device with integrated sensors and microprocessor was developed that gives immediate diagnosis, and stores data for subsequent research purpose. This device will be evaluated in perioperative situations to demonstrate the high sensitivity and specificity in patients in a clinical setting.

Pre-Hospital Advanced Airway Management (PHAAM) is a potentially lifesaving intervention. A recent Danish multicentre single country study demonstrated a 99,7% incidence of successful anaesthesiologist pre-hospital endotracheal intubation, with a PHAAM-related complication rate of 7.9%. A London study revealed a significantly higher intubation failure rate among non-anaesthesiologist physicians. In Scandinavia different types of emergency medical services (EMS) and professions provide PHAAM. The success rate of prehospital endotracheal intubation (PHETI), incidence of difficult intubation and complications in the Nordic countries is not known. The aim of this study is to define PHAAM success rate and complications in different types of Nordic EMS organisations and physician critical care teams. The study is a prospective observational study with collection of PHAAM data according to the template by Sollid et al. in the 12 participating Nordic Countries EMS/HEMS centres and physician critical care teams. The primary endpoint is PHETI success on ≤2 attempts and no complications.

A prospective observation study to screen adult obese (BMI ≥30 kg/m2) patients who were newly admitted to the medical intensive care units and turned out to be diagnosed as Obesity hypoventilation syndrome(OHS). The investigators purpose is to look into the prevalence, predictive factors, and outcomes of OHS in these critically ill patients.

The aim of the study is to identify the parameters that are associated with nocturnal hypoventilation in children and adults with cystic fibrosis. Included patients will undergo a nocturnal evaluation of their gas exchange and sleep quality by actigraphy during their annual check up. The aim is thus to identify which parameters (such as lung function parameters) are associated with nocturnal hypercapnia or hypoxemia and/or poor sleep quality

The purpose of this study is to determine if gastric bypass patients experience hypoventilation in the immediate postoperative period, and to what degree.

Obstructive sleep apnea (OSA) and Obesity-Hypoventilation Syndrome (OHS) are common conditions in obesity, which may influence the prognosis in patients undergoing surgery. There is a need for simple screening tools to identify such patients at high risk. The current multicenter observational study aims to investigate occurrence of OSA and OHS in obese individuals undergoing elective abdominal surgery and further address its impact on perioperative and postoperative complications.

The purpose of this study is to determine whether breathing pattern (specifically the inspiratory time/total respiratory cycle value) has an influence over the response to the noninvasive mechanical ventilation.

Chronic obstructive pulmonary disease (COPD) is a lung disease caused by cigarette smoke that affects millions of people. In the United States, COPD is the 3rd leading cause of death making it one of our most important public health problems. Some people with COPD get disease flares that are called acute exacerbations of COPD - or AECOPDs for short. When people get an AECOPD they experience increased shortness of breath, wheezing and cough; symptoms that often require urgent or emergent treatment by healthcare providers. In the most severe, life-threatening situations, people with AECOPDs are put on a ventilator in the emergency department and admitted to the intensive care unit. Most AECOPDs can be treated with low doses of medications called steroids. This is good because high doses of steroids can cause unwanted side effects. Unfortunately, recent studies suggest that the sickest people, those admitted to the intensive care unit needing ventilator support, need higher doses of steroids because they may have resistance to these important medications. The investigators are studying steroid resistance during very severe AECOPDs so that we can eventually develop better and safer therapies for these vulnerable people.

In clinical practice discrepancies between overnight SpO2 recordings performed by 2 devices used simultaneously are regularly observed. However, this has not been systematically studied or quantified. It is therefore important to determine if these discrepancies are anecdotic, or frequent, and to what extent this may affect decisions in clinical practice such as implementing (or withdrawing) oxygen in subjects under noninvasive ventilation (NIV) or continuous positive airway pressure (CPAP), or adjusting NIV settings.

The study aims to describe the use of Nasal High Flow (NHF) in the intensive care units of participating centers in Iberoamerica. It will describe the indications for the use, the clinical outcome of patients , and the therapeutic failure of NHF therapy in patients staying in an intensive care unit in the participant centers in Iberoamerica.
