Active clinical trials for "Respiratory Insufficiency"

To evaluate the polysomnographic performance of an automatic ventilatory mode compared with the gold standard (manual polysomnographic titration) to adjust chronic non-invasive ventilation by means of a randomized cross-over study.

Children who are in a hospital with respiratory distress often have difficulty breathing, have thick mucus, and may find it hard to eat normally. Sometimes physical therapy is used to treat these children, but it is not entirely known which methods help the children's condition. The aim of this study is to evaluate the most common physiotherapy treatment method that is currently in use in Sweden for infants who are hospitalized with a lower respiratory infection.

The purpose of this study is to learn more about problems with swallowing that could develop in patients who are very sick and need a machine to help them breathe.

In patients undergoing NIV for acute respiratory, lack of tolerance is one of the main reason of failure. This may result in a poor synchrony between the patient and the machine, leading to gross mismatching and potentially to an increased work of breathing. The investigators aim to investigate whether in these patients poorly responding to NIV the use of a sedation protocol using remifentanil will lead to an improve patient-ventilator interaction and better compliance to NIV.

PRODIGY is a prospective, multi-center, post-market, international cohort study. The primary objective of this study is to derive a score to identify subjects at risk to have respiratory depression (RD) episodes in patients undergoing opioid therapy in the hospital ward and monitored by capnography. The score will be derived by using subjects within the derivation cohort and internally validated using subjects within the validation cohort. The primary endpoint used to derive the score will be the occurrence of RD episodes derived by Capnostream 20p device memory data combined with clinical data and validated by an independent Clinical Endpoint Committee (CEC) during the study course.

The use of a written, pre-procedure checklist and positioning the patient with the head of the bed elevated have been proposed as interventions capable of preventing complications during non-elective intubation and are used intermittently in routine care -- however neither have been examined in a prospective trial.

This is a proof of concept study where the investigators aim to study the correlation between the use of a simple bedside ultrasound measurement of diaphragmatic muscle excursion with established (but time consuming) measurements made to optimize an important setting on the mechanical ventilator (positive end expiratory pressure or PEEP) in intubated adults with acute respiratory distress syndrome (ARDS) in the medical ICU.

In blunt chest trauma patients without immediate life-threatening conditions, delayed respiratory failure and need for mechanical ventilation may still occur in 12 to 40% of patients, depending on the severity of the trauma, the preexisting conditions and the intensity of initial management. In this context, non-invasive ventilation (NIV) is recommended in hypoxemic chest trauma patients, defined as a PaO2/FiO2 ratio < 200 mmHg. However, there is a large heterogeneity among studies regarding the severity of injuries, the degree of hypoxemia and the timing of enrollment. The interest of a preventive strategy during the early phase of blunt chest trauma, before the occurrence of respiratory distress or severe hypoxemia, is not formally established in the literature. Moreover, high-flow nasal oxygen therapy (HFNC-O2) appears to be a reliable and better tolerated alternative to conventional oxygen therapy (COT), associated with a significant reduction in intubation rate in hypoxemic patients. Two NIV strategies are compared: In the experimental strategy, NIV is performed after inclusion in patients with moderate hypoxemia, defined by a PaO2/FiO2 ratio < 300 mmHg. The minimally required duration of NIV was 4 hours per day for at least 2 calendar days. In the control group, patients receive oxygen from nasal cannula or high concentration oxygen mask according to the FiO2 needed to achieve SpO2 > 92%. NIV is initiated only in patients having PaO2/FiO2 ratio < 200 mmHg under COT. Investigators hypothesized that an early strategy associating HFNC-O2 and preventive NIV in hypoxemic blunt chest trauma patients may reduce the need for mechanical ventilation compared to the recommended strategy associating COT and late NIV.

Dyspnea in systemic sclerosis (ScS) constitute a major factor of functional disability. Intensity of dyspnea is sometimes discordant with objectives data from cardiopulmonary involvements, suggesting unknown additional factors. Diffuse fibrosing myopathy of bad prognosis have been reported in ScS.To now, muscular respiratory involvement has not been evaluated in ScS. Therefore, ScS patients (with or without dyspnea) could have underlying respiratory muscular involvement not detected by current standard of care with pulmonary function tests (PFT). This project is the first, to the best of our knowledge, to assess frequency of respiratory muscular involvement in ScS and to evaluate a screening strategy of this involvement.

High flow nasal oxygen therapy has been widely used but guidelines as to the optimal starting flow rate and oxygen percentage are not available. Prolonged exposure to an inappropriately high oxygen concentration should be avoided as there is increasing evidence that the production of oxygen free radicals can lead to lung damage. This pilot dose finding study will determine the optimal flow rate and oxygen concentration using HFNO2 for patients with respiratory failure requiring low, medium or high oxygen concentration from conventional low flow devices. An assessment will also be made of comfort and compliance with HFNO2.
