7 Clinical Trials for Various Conditions
This is a prospective randomized cross over study of healthy volunteers undergoing continuous positive airway pressure ventilation via a noninvasive ventilation (NIV) mask with and without the addition of nasal cannulas. Mask leak will be measured by the ventilator after 60 seconds of spontaneous resting ventilation, with each subject serving as his or her own control.
Prior to surgery the anesthesia team will be putting a breathing tube into the patient's windpipe and attaching it to a mechanical ventilator (breathing machine). This is to provide oxygen and anesthetic gas, and to help the child breathe while they're asleep. The ventilator also controls the amount of air that moves in and out of the lungs with each breath. This is called tidal volume and that amount is programmed into the machine by the anesthesia team. All of this is standard of care. As part of the study the investigators will put a small flow sensor between the patient's breathing tube and the tubing from the ventilator. This will measure the amount of air that is moving in and out of the breathing tube. The study team will record the tidal volume that is set on the ventilator and compare it to the airflow measured by the ventilator and the airflow measured by the sensor and see if there is a difference.
Prospective observational cohort study within the Pediatric Intensive Care Unit (PICU). We will perform point-of-care-ultrasound (POCUS) to quantify tricuspid regurgitant jet velocity (TRJV) on mechanically ventilated (MV) children. Mechanically ventilated (MV) children approaching extubation as per the discretion of the PICU clinical team will undergo a positive end expiratory pressure (PEEP) titration protocol in a safe and timely manner in the PICU. During this PEEP titration, POCUS will be performed by a pediatric intensivist and interpreted by a pediatric cardiologist. Medical demographics will be collected from the electronic medical record and recorded.
The purposes of our study are to: 1) determine the incidence of paradoxical response to chest wall loading in mechanically ventilated patients; 2) identify sub-populations in which it is most likely to occur (e.g., severe ARDS); and 3) standard the bedside procedure for demonstrating this physiology.
The investigators will conduct a randomized clinical trial pilot study to examine the effectiveness of a theoretically based intervention (called ReMind) encompassing two key components: (a) Resourcefulness Training for parent caregivers, and (b) daily mindfulness meditation delivered using a smart phone application (Stop, Breathe \& Think™) with an intervention (Mind Only) that consists only of daily mindfulness meditation. Both components of the intervention have been tested separately (but not combined) and both interventions can be self-tailored, which meets the vital need for these caregivers to engage in self-management activities when it is convenient for them. The investigators will test the two arms of the intervention in 30 parents of technology-dependent children, 15 parents in each group. The investigators will collect mixed data at baseline, 3 months and 6 months after subject enrollment to describe changes in proximal and distal outcomes. The investigators aim to: 1. Evaluate the intermediate (3 month) and long-term (6 month) effects of the ReMind and Mind Only interventions on study mediators (HPA Axis Function and stress, cognitive factors, resourcefulness) and determine if there are different effects between ReMind and Mind Only interventions. 2. Evaluate the differences in distal psychological (Mental Health Related Quality of Life, Depressive Cognitions, Depressive Symptoms, Anxiety, Caregiver Burden), physical (Physical Health Related Quality of Life), and cost outcomes between subjects in the ReMind and Mind Only arms over time. 3. Determine the moderating effects of parents' social support, demographics (age, gender, family income) and children's functional status on (a) proximal outcomes and the relationship between (a) the intervention arm and distal outcomes, and (b) HPA Axis Function, stress, cognitive factors and distal outcomes. 4. Evaluate the impact of decentering on the association between the interventions and the proximal and distal outcomes. 5. Explore differences in neurological processing (DMN and TPN) and decentering in proximal and distal outcomes associated with each intervention.
This study is being conducted to evaluate if wearing a non-invasive breathing support device over the chest/abdomen improves markers of breathing in patients with lung injury requiring high-flow oxygen. The breathing support device consists of a plastic shell that sits over the chest and abdomen and connects to a vacuum that helps the chest expand with breathing. This breathing support is known as continuous negative external pressure (CNEP). Study findings will help determine if this breathing support device might be useful for patients with acute hypoxemic respiratory failure (AHRF).
One-lung ventilation (OLV) with resting of the contralateral lung may be required to allow or facilitate thoracic surgery. However, OLV can result in severe hypoxemia, requiring a mechanical ventilation approach that is able to maintain adequate gas exchange, while protecting the lungs against postoperative pulmonary complications (PPCs). During OLV, the use of lower tidal volumes is helpful to avoid over-distension, but can result in increased atelectasis and repetitive collapse-and-reopening of lung units, particularly at low levels of positive end-expiratory pressure (PEEP). Anesthesiologists inconsistently use PEEP and recruitment maneuvers (RM) in the hope that this may improve oxygenation and protect against PPC. Up to now, it is not known whether high levels of PEEP combined with RM are superior to lower PEEP without RM for protection against PPCs during OLV. Hypothesis: An intra-operative ventilation strategy using higher levels of PEEP and recruitment maneuvers, as compared to ventilation with lower levels of PEEP without recruitment maneuvers, prevents postoperative pulmonary complications in patients undergoing thoracic surgery under standardized one-lung ventilation.
