Filter by:The purpose of this study is to investigate a specific approach to patient care called a time-limited trial (TLT). This approach is sometimes used for people who develop critical illness and are cared for in an intensive care unit (ICU). A time-limited trial is a plan made together by medical teams, patients with critical illness (if they can take part), and their families or other important people helping to make their healthcare decisions. A time-limited trial starts with a discussion of the patient's goals and wishes. Then, a plan is made to use ICU treatments for a set period of time to give the patient the chance to recover. After this time, the patient's response to treatment will be reviewed to help guide what to do next. Medical teams consider this kind of plan when it is not clear if a patient can recover to a quality of life that is acceptable to him or her. With a time-limited trial, patients, families, and medical teams experience this uncertainty together. The main goal of this study is to find the best way to use TLTs for patients in the ICU who have trouble breathing and need mechanical ventilation to help them breathe. The hypothesis is that optimal time-limited trial delivery will reduce the time patients with acute respiratory failure spend in the ICU and will improve the intensive care unit experiences for their families and clinicians.
The purpose of this study is to evaluate the effect of an 8-week walking program on blood pressure in inactive older adults with respiratory impairment, a condition where lung function is sub-optimal for a person's age. Older adults with respiratory impairment have greater risks of death by cardiovascular disease (CVD) compared to those without respiratory impairment, and this may be partly driven by higher resting blood pressure. One way to lower blood pressure is to increase the number of daily steps achieved throughout the course of everyday life ('lifestyle steps'), and previous research shows that an additional 3,000 lifestyle steps/day is effective for achieving this. However, whether an increase in daily lifestyle steps is effective for reducing blood pressure in senior-community dwelling older adults with respiratory impairment is unknown. Understanding how increasing daily steps impacts blood pressure in this understudied population is important for informing future strategies for tackling cardiovascular disease risk in those with lung dysfunction.
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.
The METEOR Trial will compare four implementation strategies-traditional online education, protocol-directed care, interprofessional education, and a combination of protocol-directed care and interprofessional education-to test the hypotheses that interprofessional education is superior to traditional online education as an implementation strategy in the intensive care unit (ICU) and the benefits of interprofessional education are increased when interprofessional education is paired with a clinical protocol. Additionally, the trial will also test the hypothesis that preventive post-extubation NIV for high-risk patients and preventive post-extubation HFNC for low-risk patients are both superior to current clinical practice (i.e., conventional post-extubation oxygen therapy).
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.
The purpose of this research is to evaluate two oxygen saturation goals for newborns with pulmonary hypertension. Participation in this research will involve random assignment to one of two oxygen saturation goals, review of the medical record and targeted echocardiograms.
This is a study to compare the new ShuttleScope with the standard Macintosh Laryngoscope
This study aims to establish the treatment scheme of Yiqi Huoxue Huatan granule for chronic obstructive pulmonary disease (COPD) with chronic respiratory failure (CRF), reducing mortality, improving quality of life and forming high quality evidence.
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.
