Filter by:The aim of the study is to asses safety and indications and contraindications for performing bronchofiberocopy (FB) with respiratory support methods, i.e. non-invasive ventilation (NIV) and high flow nasal oxygen therapy (HFNO). Additionally, researchers want to determine how using these methods could avoid the risk of most common complications such as: hypoxemia-related events, decompensation of chronic respiratory failure, worsening of gas exchange, hemodynamic instability.
Respiratory physiology involves a complex interplay of elements including control of breathing, respiratory drive, pulmonary mechanics, distribution of ventilation and gas exchange. Body position may also play an important role in respiratory mechanics. While effective methods exist for measuring these variables, they are typically measured in isolation rather than in combination. In pulmonary disease, decreasing mechanical stress and strain and optimizing transpulmonary pressure or the distending pressure across the lung, minimizing overdistention and collapse are central to clinical management. Obesity has a significant impact on pulmonary mechanics and is a risk factor for obstructive sleep apnea (OSA). However, our understanding of these elements is limited even in the general population. The investigators plan to use various validated methods to assess control of breathing, respiratory drive, distribution of ventilation and gas exchange to obtain a better understanding of underlying physiologic signatures in patients with and without obesity and the role of posture/position, with a secondary analysis comparing participants with and without obstructive sleep apnea.
Respiratory failure occurs when the lung fails to perform one or both of its roles in gas exchange; oxygenation and/or ventilation. Presentations of respiratory failure can be mild requiring supplemental oxygen via nasal cannula to more severe requiring invasive mechanical ventilation as see in acute respiratory distress syndrome (ARDS).It is important to provide supportive care through noninvasive respiratory support devices but also to minimize risk associated with those supportive devices such as ventilator induced lung injury (VILI) and/or patient self-inflicted lung injury (P-SILI). Central to risk minimization is decreasing mechanical stress and strain and optimizing transpulmonary pressure or the distending pressure across the lung, minimizing overdistention and collapse. Patient positioning impacts ventilation/perfusion and transpulmonary pressure. Electrical impedance tomography (EIT) is an emerging technology that offers a noninvasive, real-time, radiation free method to assess distribution of ventilation at the bedside. The investigators plan to obtain observational data regarding distribution of ventilation during routine standard of care in the ICU, with special emphasis on postural changes and effects of neuromuscular blockade, to provide insight into ventilation/perfusion matching, lung mechanics in respiratory failure, other pulmonary pathological processes.
This is a study to compare the new ShuttleScope with the standard Macintosh Laryngoscope
This is a research study to determine if identifying an optimal level of positive end-expiratory pressure (PEEP) targeted specifically to individualized patient characteristics will shorten the time on the ventilator. Participants will have catheter placed through the nose into the esophagus to measure the pressure inside the chest. This catheter will remain until the patient is freed from the ventilator. Participants will be randomized to usual care or to have the level of PEEP determined by the esophageal balloon pressure readings. The total time spent on the ventilator will be recorded.
Respiratory failure is the danger for the patients admitted in ICU, mechanical ventilation could save a lot of patients' life, however, it prolongs patients' ICU stay and hospital stay. High flow nasal cannula (HFNC) has advantages of PEEP effects, reducing dead space, increasing EELV and improving comfort, and it has been used to treat respiratory failure patients. In recent study, HFNC could improve mortality of respiratory failure patients with P/F<200mmHg in the subgroup. The investigators want to start a randomized controlled study to evaluate the effects of HFNC on the patients with respiratory failure.
Intensive care unit acquired weakness (ICU-AW) is common and dramatically affect recovery. The purpose of this study is to determine whether electric acupuncture therapy is effective in the treatment of ICU-AW especially in the patients receiving mechanical ventilation with sepsis or multiorgan system failure.
The aim of this study is to better discriminate respiratory muscle dysfunction by comparing the measurements of thoracoabdominal motion obtained by an optoelectronic recording and the conventional tests of respiratory muscle strength. The final objective is to better select in the future the patients who need more specific assessment of diaphragmatic function like "maximal transdiaphragmatic pressure" measurement and "phrenic nerve stimulation".
