10 Clinical Trials for Various Conditions
The goal of this observational study is to determine if Intrapulmonary Percussive Ventilation (IPV) improves lung compliance in children receiving conventional invasive mechanical ventilation. The main questions it aims to answer are: 1. Does IPV improve lung compliance 15 minutes after and 3 hours after receiving one treatment in a heterogeneous group of pediatric patients? 2. Does IPV improve lung compliance in patients with Pediatric Acute Respiratory Distress Syndrome (PARDS), and what is the degree of change compared to those without PARDS? 3. What is the effect of IPV on lung compliance according to PARDS severity (mild-moderate disease vs. severe disease). 4. What is the incidence of adverse effects of IPV? Participants will receive IPV because their medical team feels it will help their lung recovery and has already determined them to be safe candidates to receive this therapy, which is a standard airway clearance modality already routinely used in our PICU. Nothing additional will happen to participants as a result of this study. Enrolling in this study simply gives the study team permission to collect specific health information that identifies your child for research purposes, which may include results from medical tests found in their medical record and information from your child's bedside monitor and ventilator. This information will be collected before and after the IPV treatments to evaluate their response to the therapy.
No interventions outside the normal course of patient care. The investigators will be collecting data at specified points throughout the casting process. The proposed study will measure lung compliance during the casting process for spinal manipulation. Research questions include: Is there a quantifiable change in lung compliance during the casting process? Is there an individual change in lung compliance over time comparing collection points at each cast change? Is there a change in appearance of flow-volume loop? Is there a decrease in oxygen saturation from post-induction baseline? The investigators hypothesize that there is a change in lung compliance and a decrease in oxygen saturation during the casting process.
This is a null hypothesis study. The investigators hypothesize that there will be no difference in changes in dynamic compliance when measured at 15, 30, 45 and 60 minute intervals after administration of either surfactant and there will be no differences in the number of doses needed between the two surfactants in premature infants admitted to our NICU.
The purpose of the study is to find out how the blood flow changes in the lungs of people with pulmonary hypertension compared to healthy individuals without pulmonary hypertension. We would like to find out if there are differences in how blood flows when subjects are given a drug to dilate (widen) the arteries in their lungs and when they breathe extra oxygen. We will compare the results to when subjects don't receive any drug or extra oxygen. We hope that knowing about these differences will help us to better understand pulmonary hypertension and how to diagnose it earlier.
The goal of this interventional crossover study, in intubated and mechanically ventilated Acute Respiratory Distress Syndrome (ARDS) patients, is to compare two positive end-expiratory pressure (PEEP) titration techniques regarding: respiratory mechanics, gas exchange, changes in aeration, ventilation/perfusion matching its impact on cardiac function, especially the right heart (RH). The PEEP titration techniques are: PEEP selection based on low PEEP/high FiO2 table ("PEEPARDSnet") and lung recruitment maneuver (LRM) plus PEEPdec titration based on the best compliance of the respiratory system("PEEPLRM").
The study proposes to evaluate a patient navigation intervention among a sample of 446 individuals referred for CT-based lung cancer screening in an urban safety-net setting.
The study hypothesis is that clearer visual presentation of guideline recommendations and educational outreach, or academic detailing, can improve guideline compliance. However, it will investigate other aspects of screening-related decision-making, such as provider and patient beliefs about screening, provider-patient communication and patient's willingness to forgo expected testing. The research question is whether educational interventions can decrease non-compliance with screening guidelines for 5 common cancers.
Typically doctors adjust the settings on the ventilator to ensure that children receive enough help to decrease the work they perform to breathe, receive enough oxygen through the machine to pass into the blood and to the organs, and remove acid that builds up in the blood. However, sometimes the settings we choose can result in damage to the lungs. We are trying to find a better way to determine the best ventilator settings, which can minimize potential damage to the lungs, and still provide children with enough support to decrease the work they have to do to breathe. We believe we can personalize these choices for each child by looking at the pressure that is generated in the chest while children breathe with the ventilator. This is accomplished by using a small tube which goes through the nose and into the esophagus or stomach, which is hooked up to a computer or the ventilator to monitor pressure. This same tube can then also be used to monitor how much work children need to do to breathe as we are turning down the ventilator in preparation to remove the breathing tube.
One course of steroids given to a mother before a premature delivery helps the lungs of the premature infant and decreases breathing problems. One course of antenatal steroids is the standard of care for threatened premature deliveries. It is unclear as to how long the benefit of one course of steroids last. The most benefit to the baby's lungs seem to occur if the steroids are given at least 24 hours before but within 7 days of a premature delivery. It is difficult to predict the timing of a preterm delivery so deliveries often do not occur within this time period. We hypothesize that the benefits of the steroids to the lungs wear off if the steroids are given more than 14 days before a preterm delivery, and that in these circumstances an extra course of steroids will help the premature baby's lungs and the premature baby will have less breathing problems as shown by lung function testing.
The purpose of this study is to understand why patients in the World Trade Center program have continuing breathing problems. This study will improve investigators understanding of breathing problems among individuals with World Trade Center exposure by allowing them to review and monitor medication use, lung function, and examine other conditions that can contribute to problems with breathing. The findings from the study will help investigators understand why some people have persistent lower respiratory symptoms (breathing problems) after their exposure to World Trade Center dust and fumes, and may help guide better management and treatment of these symptoms.
