Recruiting studies
- NCT04448145Recruiting
Study why COVID lasts after recovery
This study looks at what factors may make COVID-19 symptoms or infection effects last after someone has recovered. It also collects certain body samples to better understand why this persistence happens.
New York, New YorkAges 7 years+ - NCT04460859Recruiting
Testing an electrical monitor in moderately severe lung failure
This trial tests a bedside breathing and lung-monitoring method that uses small electrodes on the chest. It is meant for people with moderate to severe ARDS (a serious lung inflammation problem) who are on a breathing machine, to help guide care.
São PauloAges 18 years+ - NCT04461821Recruiting
Breath test to study disease in children
This study uses a special machine to analyze exhaled breath to learn about different illnesses in children and teens. It may help researchers find breathing “signals” that reflect conditions like breathing problems, nervous system issues, or new/worsening type 1 diabetes.
BaselAges Up to 22 years - NCT04484727Recruiting
Measure lung pressure and breathing in ventilated ICU patients
This study measures lung pressures and breathing mechanics during planned or emergency breathing machine (ventilator) treatment. It may help doctors better understand lung behavior in both healthy and breathing-distressed lungs to improve care.
Gothenburg, Västra Götaland CountyAges 18 years+ - NCT04524091Recruiting
Predict breathing effort response to higher ventilator pressure
This trial looks at how much breathing effort changes when the ventilator uses a higher pressure in people who are recovering from ARDS. The goal is to predict who will respond better so care can be adjusted more safely and effectively.
San Martín, Buenos AiresAges 18 years+ - NCT04538937Recruiting
Study of high eosinophils causing lung/airway damage
This registry study looks at adults with high eosinophils (a type of immune cell) that are believed to be causing damage in the airways or lungs. It aims to better identify these eosinophils and understand what is going on so future treatments can improve.
InnsbruckAges 18 years+ - NCT04545424RecruitingPhase 2
Testing cooling treatment for severe lung failure in ICU patients
This trial tests whether therapeutic cooling (hypothermia) can improve outcomes in people with ARDS, a serious lung condition causing breathing failure. It may help by reducing harmful inflammation and lung injury, but eligibility is time-sensitive and requires ICU monitoring.
Los Angeles, CaliforniaAges 18–85 - NCT04666246Recruiting
Studying breathing effort in people with COVID-19 breathing failure
This study looks at how hard people with COVID-19 are working to breathe when they have serious breathing trouble but are not yet fully on a breathing machine. The results may help doctors better understand breathing support needs and improve care.
ModenaAges 18–80 - NCT04707729Recruiting
Checking when to intubate patients on nasal high-flow oxygen
This study looks at a scoring system (ROX Index) to help decide the best timing to place a breathing tube (intubate) for adults who are struggling to get enough oxygen while using nasal high-flow (NHF). The goal is to see if using this timing approach can improve care for acute lung failure in the ICU.
Chicago, IllinoisAges 18–120 - NCT04754854Recruiting
Testing less blood recirculation during veno-venous ECMO
This trial studies whether a change in how a veno-venous ECMO machine works can reduce “blood recirculation” (blood returning to the circuit too quickly) in people with severe lung failure. It may help improve oxygen levels in adults whose ARDS is not responding to standard treatment.
BerlinAges 18 years+ - NCT04772183Recruiting
Testing pulse oximeters against a blood-gas test in ICU
This trial compares how well different fingertip pulse oximeters measure oxygen levels, using an arterial blood test as the reference. It may help improve oxygen monitoring for ICU patients, especially when measurements can be hard or inaccurate.
Montreal, QuebecAges 18 years+ - NCT04775134Recruiting
Checking leftover COVID virus after recovery
This study looks for whether small amounts of the COVID virus are still present in the lungs after infection. It may help doctors understand how long the virus can remain and inform future care, using tissue removed during a medically needed lung procedure.
LeuvenAges 18 years+ - NCT04883463Recruiting
Brain and spinal stimulation to improve breathing after SCI
This trial tests a neuromodulation treatment to improve breathing in people living with a cervical spinal cord injury who have significant breathing problems. If you qualify, you would have regular weekly testing over many months to see whether breathing and breathing support needs improve.
Los Angeles, CaliforniaAges 18–75 - NCT04887623Recruiting
Blood and breathing marker tracking in hospitalized COVID-19
This study follows hospitalized people with recent COVID-19 to see how infection and inflammation markers change over time. It may help doctors better understand what’s happening in the body as breathing problems develop and treatments are given.
Hradec KrálovéAges 18–90 - NCT04903262Recruiting
Extra CO2 removal to protect lungs in moderate ARDS
This study tests an “extra-CO2 removal” breathing support approach to help protect the lungs in people with moderate ARDS, a serious lung injury. You would be on a ventilator for a short time, and the team would check whether this approach improves breathing outcomes while aiming to be safer for the lungs.
BolognaAges 18–100 - NCT07699666Recruiting
Cord clamping timing for preterm babies
This study compares waiting a bit before clamping the umbilical cord versus clamping it right away for babies born between 32 and 37 weeks of pregnancy. It helps determine which approach may be better for preterm infants.
Tunis, Tunis GovernorateAges birth+ - NCT04941326Recruiting
Spinal mobilization for breathing in Parkinson’s disease
This study tests whether a hands-on therapy to the spine can improve breathing measures in people with Parkinson’s disease. If you qualify, you would receive spinal mobilization and have your breathing assessed to see if it helps.
BoluAges 50–85 - NCT04959734Recruiting
Study of COVID-19 effects on emergency visits for infant lung infections
This study looks at how the COVID-19 era changed emergency department visits for young children with breathing problems, such as bronchiolitis or first-time viral wheeze. It may help doctors understand trends in these illnesses and plan better care during outbreaks.
LeicesterAges birth–2 years - NCT04966793Recruiting
Study bacteria patterns in bronchiectasis and how they change
This study looks at how bacteria live in the lungs of people with bronchiectasis and how they may adapt over time. It may help researchers understand why infections keep coming back and how to better manage chronic lung colonization.
Hangzhou, ZhejiangAges 18–79 - NCT05011877Recruiting
Study for sleep testing after sudden breathing trouble
This trial studies people who unexpectedly end up in the hospital or emergency room because of a sudden worsening in breathing that leads to too much carbon dioxide. It may help doctors understand whether sleep-related breathing issues contribute and how to better prevent repeat episodes.
Toronto, OntarioAges 18 years+ - NCT05013944Recruiting
Join a patient registry to support future research
This trial is a “patient registry,” which collects health information over time to help researchers plan and run future studies. It may help by contributing your experience so new treatments can be tested more effectively.
Arlington Heights, IllinoisAges 18 years+ - NCT05014581RecruitingPhase 3
Testing vasopressors to prevent low blood pressure during intubation
This trial studies whether using blood-pressure support medicines (vasopressors) during breathing tube placement (intubation) can prevent dangerous drops in circulation (“cardiovascular collapse”). It may help patients stay stable during and after intubation, especially in critical illness.
NantesAges 18–90 - NCT05030207Recruiting
Test a new CT scan method for lung cancer radiation planning
This study tests whether a real-time, breathing-adapted CT scan (called 4DCT) can be done safely and work well for planning radiation treatment for lung cancer. It may help make radiation planning more accurate while checking if the scan process is practical for patients.
Blacktown, New South WalesAges 18 years+ - NCT05063149RecruitingPhase 3
Preemie immune treatment to prevent lung infections and wheezing
This study tests whether a bacterial “lysate” medicine, given to preterm babies, can reduce respiratory (lung) infections and wheezing. It may help protect babies’ airways during the vulnerable first months after birth.
Rotterdam, South HollandAges 1 month–2 months
