Breathing training for people with ALS to improve cough
This study tests a breathing and expiratory muscle training program to help people with ALS cough more effectively. It may help reduce breathing and airway trouble by strengthening the muscles used for cough in early-stage ALS.
Fort Lauderdale, FloridaAges 18–90 - NCT05903001Recruiting
Breathing muscle testing to help track lung disease
This study checks whether measurements of your breathing muscle (the diaphragm) can act as a useful “biomarker” to track lung disease. You might be asked to do breathing tests and follow study instructions, and your results may help researchers better monitor COPD, asthma, fibrosis, or pulmonary hypertension.
Aachen, North Rhine-WestphaliaAges 18 years+ - NCT05661032Recruiting
Testing new ways to identify respiratory viruses
This study tests “new technologies” to identify what virus is causing a respiratory illness, using samples taken from inside your nose. It may help doctors get faster, more accurate answers about the cause of your symptoms.
Portsmouth, HampshireAges Any age - NCT05462600Enrolling by invitation
Breathing monitoring test in non-smokers
This study measures how you breathe and how well oxygen and carbon dioxide move in and out of your lungs. It’s mainly a monitoring study to help researchers understand breathing patterns during a breathing test.
La Jolla, CaliforniaAges 18 years+ - NCT05164744Recruiting
MRI study of heart tissue changes after COVID-19
This study uses a heart MRI to look for leftover (healing) changes in heart tissue after COVID-19. It may help researchers better understand what ongoing heart effects can happen after infection.
Brooklyn, New YorkAges 18 years+ - NCT05150483Recruiting
Study of a blood test in new severe breathing failure
This trial looks at how a test might help evaluate adults who come to the emergency room with a brand-new, sudden breathing problem that needs high-flow oxygen. It may help doctors identify what’s going on faster and guide care in the early hours.
Athens, AtticaAges 18 years+ - NCT05026749RecruitingPhase 3
Azithromycin for severe RSV breathing failure in young children
This trial tests whether azithromycin (an antibiotic) can improve outcomes for babies and young children in the ICU who have RSV causing serious breathing problems. It mainly looks at children who start strong breathing support soon after RSV symptoms begin.
Birmingham, AlabamaAges 3 days–2 years - NCT04959526Recruiting
Testing lung stiffness and breathing function in healthy adults
This study compares a lung ultrasound method (shear-wave elastography) with breathing function tests to see how well they match. It may help researchers better understand how to measure lung health using imaging versus breathing tests.
Rochester, MinnesotaAges 18 years+ - NCT03753412Recruiting
Rehab program for adults after ICU recovery on ECMO
This trial looks at a recovery and rehabilitation approach for adults who were very sick and needed a machine called ECMO to support breathing and heart function. It may help people regain strength and function after a severe ICU illness.
LondonAges 18 years+ - NCT05102825Recruiting
Lung MRI registry to track breathing health
This study builds a lung imaging registry using MRI pictures to learn how breathing health looks and changes. It may help researchers understand lung problems and how well different people can complete breathing-related MRI scans.
Vancouver, British ColumbiaAges birth–99 years - NCT05501587Recruiting
Respiratory Health Registry measuring lung function in different groups
This registry study collects information and measures lung function to better understand respiratory health across people with cystic fibrosis, other lung diseases, and healthy volunteers. Your results may help researchers track lung health and improve future research and care.
Vancouver, British ColumbiaAges birth–99 years - NCT05857891Recruiting
Erythropoietin to help clear lung fluid in ARDS
This trial tests whether erythropoietin (EPO), a medicine that affects red blood cell production, can help clear extra fluid from the lungs in people with acute respiratory distress syndrome (ARDS). If it works, it could improve breathing and reduce lung fluid buildup during critical illness.
Wenzhou, ZhejiangAges 18 years+ - NCT05965128Recruiting
Testing a new 3-step diagnosis for fever and lung infections
This study tests a new, step-by-step way doctors identify what’s causing sudden fever and respiratory infections (like pneumonia or flu-like illness). It may help clinicians diagnose faster and choose the right next care.
Lanzhou, GansuAges 12–100 - NCT05990101Recruiting
Awake prone positioning for low oxygen in the ICU
This trial tests whether lying on your stomach (prone positioning) while awake can help you breathe better when you are in the ICU with low oxygen levels. It may reduce the need for a breathing tube.
KaunasAges 18 years+ - NCT06000527Recruiting
A French study on juvenile recurrent respiratory papillomatosis
This study is creating a national group of patients with juvenile recurrent respiratory papillomatosis, a condition causing wart-like growths in the airway. It aims to learn more about the disease and improve care.
ParisAges Any age - NCT05095090Recruiting
Study of hospital patients with breathing problems
This study looks at patients admitted to the hospital with acute breathing issues or those with ongoing lung conditions. It aims to better understand these conditions and may help improve future care.
LeicesterAges 18–90 - NCT06271213Recruiting
Gut-lung study for children with breathing problems
This study looks at how the gut and lungs affect breathing problems in children. It compares samples from children with and without respiratory illnesses to understand why some children get sicker than others.
GlasgowAges birth–16 years - NCT06013319RecruitingPhase 3
Esmolol for better oxygen in ARDS patients
This trial tests if esmolol, a heart-slowing drug, can improve oxygen levels in patients with acute respiratory distress syndrome (ARDS) who are on a breathing machine. It may help by adjusting heart rate to a specific range.
Jinan, ShandongAges 18–65 - NCT04158479Recruiting
Registry for people on ECMO life support
This registry collects information about people who are placed on ECMO, a heart-lung machine used to support breathing and/or circulation. It may help doctors better understand who benefits and how to manage ECMO in the future.
Beijing, Beijing MunicipalityAges Any age - NCT05540834RecruitingPhase 2
Testing blood-clot guidance for ICU patients with severe lung failure
This Phase 2 trial tests whether using a blood test that shows clotting strength and “clot breakdown time” can help guide treatment for people in the ICU with acute respiratory failure from infection. If you qualify, the team will use these blood results to decide on clot-related therapy and compare outcomes to standard care.
Liverpool, New South WalesAges 18–75 - NCT07845305Enrolling by invitation
Breathing tube placement with sedation only to preserve breathing
This study tests whether giving only sedation (not a paralytic drug) during emergency breathing tube placement can help you keep breathing on your own. It aims to see if this approach is safer and helps recovery.
