Filter by:Purpose: To evaluate the effectiveness of newborn resuscitation feedback supported by a mobile health application called LIVEBORN; secondarily, to evaluate the relative effectiveness of real-time guidance vs debriefing. Participants: Newborns and Nurse midwives Procedures (methods): This is a pre-post interventional trial to evaluate the effectiveness of LIVEBORN feedback. The investigators will use a randomized design to test the relative effectiveness of two modes of feedback: real-time guidance versus debriefing. Given the potential for feedback interventions to have spillover effects, the investigators will randomize by cluster (i.e., facility) rather than by individual. The study will begin with an approximately two-month pilot phase to establish systems for implementation of recommended training and simulation practice and consistent use of LIVEBORN for observations. After these systems have been successfully established, the investigators will initiate the pre-post trial. The control phase will last six months followed by implementation of LIVEBORN feedback in an intervention phase lasting 12 months.
Hypoxemia during endotracheal intubation is one of this procedure's most frequent and severe complications, which can lead to cardiac arrest and other adverse outcomes. Although various studies have been conducted to ensure the safety of endotracheal intubation, most of them have focused on the physiological changes during the procedure in surgical settings, where general anesthesia is administered to healthy subjects. However, the physiological characteristics of critically ill patients who require endotracheal intubation in the intensive care unit (ICU) may differ from those of healthy subjects. When comparing the oxygen saturation-dissociation curve of healthy subjects and critically ill patients, the latter show a steeper decline in oxygen saturation (SpO2) below 90% when hypoxemia occurs. Clinically, it is difficult to maintain or recover oxygen saturation when it drops. Therefore, preoxygenation is also essential for critically ill patients with a relatively small lung reservoir, as it can help maintain higher and longer oxygen saturation during endotracheal intubation. For this reason, apneic oxygenation was proposed in the 1950s as a method of oxygen delivery during general anesthesia for surgery, and clinical randomized controlled trials (RCTs) applying it to critically ill patients in the ICU have been conducted since 20 years ago. In an observational study by Macamn et al., the adjusted odds ratio (OR) of a bag valve mask was 1, while that of a high-flow nasal cannula (HFNC) was 5.75 and that of non-invasive ventilation (NIV) was 0.10 when different preoxygenation methods were used. n FLORARI 2, a large-scale clinical RCT comparing NIV and HFNC with or without apneic oxygenation, NIV was significantly more effective than HFNC in reducing severe hypoxemia. Based on these previous studies, the investigators can infer that supplying oxygen during laryngoscopy is not very effective in preventing hypoxemia in critically ill patients. However, there is no guideline on which device to choose for preoxygenation in the ICU, and NIV or HFNC are selected according to the operator's preference. This is because few studies have examined the physiological effects of these devices on patients. Therefore, in this study, the investigators aim to compare the clinical outcomes and adverse events of NIV and HFNC as preoxygenation methods for endotracheal intubation in critically ill patients with acute respiratory failure and to evaluate their physiological effects using electrical impedance tomography.
The goal of this study is to better understand in changes in lung compliance as indicated by driving pressure (a non-invasive marker) following changes in positive end expiratory pressure (PEEP; a standard of care ventilator parameter). The main question it aims to answer is: The time to stability of driving pressure after a change in PEEP is made Type of study: observational study participant population/health conditions Participants will undergo a "best PEEP trial" which is a standard intensive care intervention for patients undergoing invasive mechanical ventilation. This involves changing the patient's PEEP and looking for response in driving pressure. This will be done in a more protocolized format and data will be collected.
The goal of this research study is to assess the FDA approved technique for inserting a feeding tube (gastrostomy) along with a breathing tube (tracheostomy) for patients that cannot breathe or eat on their own in the ICU (Intensive Care Unit). All subjects in the study will receive a tracheostomy, but each patient will be randomly assigned a common method for gastrostomy placement. The placement of the tube and tracheostomy will occur as part of normal clinical practice. Researchers will compare subjects in the control group and the intervention group to evaluate the benefits of performing a tracheostomy and gastrostomy tube at the same time. Researchers will also evaluate the likelihood of the PUG procedure decreasing a patient's length of stay in the ICU.
The goal of this prospective interventional crossover randomized physiological study is to investigate the reliability of Pressure Muscle Index (PMI) - as an estimation of inspiratory effort - at different levels of expiratory cycling during pressure support ventilation. PMI will be compared with the esophageal pressure swing that is considered the gold standard technique. This study aims to answer to the following questions: - which is the optimal expiratory cycling threshold where PMI better correlates with the esophageal pressure swing? - what is the optimal correlation between the occlusion pressure (Poc) estimated by an expiratory occlusion manoeuvre and P0.1 with PMI obtained at various degrees of expiratory cycling threshold? - does airway resistance - evaluated by using esophageal pressure - correlate with the estimation of airway resistance on the pressure-time waveform by a high percentage of expiratory cycling mimicking the interrupter technique?
The aim of this study is to identify existing definitions and therapeutic approaches for acute right ventricular injury (RVI) in patients receiving extracorporeal membrane oxygenation (ECMO) for respiratory support. The objective of the study is to generate expert consensus statements on the definition and management of acute RVI in this high-risk patient population, using a Delphi method. The standardised RVI definition during ECMO for respiratory support and a consensus-based management approach to RVI will facilitate systematic aggregation of data across clinical trials to harmonise patient selection and compare therapeutic interventions.
In this preliminary, crossover investigation the investigators will examine the effect of oxygen supplementation on the recovery of breathing in the immediate post-anesthesia period.
The goal of this interventional trial is to learn about lung volume recruitment (LVR) and expiratory muscle strength training (EMST) in a total of up to 39 patients diagnosed with ALS. The following aims will be addressed: 1. Determine the impact of combined LVR and EMST on cough strength and respiratory function in individuals with ALS. 2. Determine the impact of combined LVR and EMST on patient-reported dyspnea and bulbar impairment. 3. Describe the effect of combined LVR and EMST on patient- and caregiver reported burden and quality of life.
This study aims at determining whether diaphragm ultrasound examining diaphragm thickening fraction, excursion and density before and after surgery can predict respiratory complications in the postoperative period. Patients scheduled for major elective abdominal, pelvic or vascular surgery will be included in the study and diaphragm ultrasound is performed before surgery and after surgery in the postoperative ward. Physiological parameters, laboratory parameters, data on surgery and anesthesia and comorbidities will be registered. Complications such as pneumonia, desaturation, need for intubation and other respiratory events up to 30 days will be registered and later correlated with the diaphragm measurements.
The goal of this feasibility study is to learn whether a new approach to breathing tube removal within the Intensive Care Unit is safe and acceptable to participants who require a breathing tube for the management of severe breathing difficulties. The main questions it aims to answer are: - What is the recruitment rate to the study over 12 months? - Is the study design acceptable and safe to participants? Participants will receive high flow nasal oxygen before their breathing tube is removed. The investigators will compare this with standard practice of applying conventional, low-flow oxygen after the breathing tube removed to see if this effects the rate of repeat breathing tube insertion. The investigators hypothesise that they will recruit 30 participants to the study protocol (15 participants in each group) over 12 months and that our study protocol will be tolerable and acceptable to participants.
