This study is testing whether a simple measurement from an ear sensor can help emergency room doctors quickly tell if a patient's sudden breathlessness is caused by heart failure (congestive) or something else like asthma or pneumonia (non-congestive). Researchers will place a sm…

This study aims to see if a quick, portable ultrasound scan can help emergency room doctors figure out why a patient is suddenly struggling to breathe. Researchers will test if looking at a major vein in the belly and scanning the lungs and heart can accurately tell if the proble…

This study is testing if using a portable lung ultrasound machine during emergency calls for severe breathing trouble helps doctors make a more accurate diagnosis and choose the right treatment faster. It involves 40 adult patients with severe shortness of breath who are treated …

This study is testing if using a bedside ultrasound machine can help emergency doctors quickly and correctly figure out what's causing sudden, severe shortness of breath in people over 65. Researchers will compare the usual care to a new approach where doctors use ultrasound on t…

This study is testing whether a device called the Lung Master can help people breathe better by improving lung capacity. Healthy adults in two age groups (19-35 and 65+) will use the device at home daily for one month while tracking their use. Researchers will measure lung functi…

This study is testing a personalized oxygen therapy program to help hospitalized cancer patients who experience severe shortness of breath. Researchers want to see if structured oxygen delivery and supportive therapies can reduce breathing difficulty more effectively than standar…

This study is testing whether starting a structured exercise and education program soon after hospitalization can help people recover better from a serious lung blood clot (pulmonary embolism). Researchers will compare patients who do the 6-8 week rehab program to those who get s…

This study is testing whether special breathing exercises can help women feel less short of breath and more active during chemotherapy for early-stage breast cancer. Participants will use a small handheld device that makes breathing in a little harder, which may strengthen their …

This study is testing if using a simple hand fan can help prevent or reduce shortness of breath, a common side effect of the heart medication ticagrelor. It will involve 110 patients in a hospital's heart unit who are taking this medication for the first time after a heart event.…

This study is testing whether inhaling menthol can help relieve the feeling of shortness of breath, especially in people with COPD. Researchers will compare menthol to a placebo in healthy volunteers and people with COPD during breathing tests and light exercise. The main goal is…

This study is testing whether the drug tadalafil can help reduce shortness of breath in Veterans who have both COPD and high blood pressure in their lungs. 126 participants will be randomly assigned to receive either tadalafil or a placebo pill for six months, and neither they no…

This study is testing a new type of MRI scan that uses a safe, inhaled gas to create detailed pictures of how well the lungs and blood are working together. Researchers want to see how these pictures change in people with different lung and blood conditions, like scarring lung di…

This study aims to understand why people feel short of breath. Researchers will test 50 adults who have been referred for a standard exercise breathing test. They will compare results from a new, simple breathing measurement to see if it can help explain the cause of breathing di…

This study aims to understand if weakness in the main breathing muscle (the diaphragm) is common in people with lung diseases like asthma, COPD, fibrosis, or pulmonary hypertension, and if it can predict future health problems. Researchers will measure muscle strength, lung funct…
