Clinical trials: Ultrasonography, Doppler
Pulmonary Hypertension
Measurements and Characterization of Doppler Signals From the Right Chest in Pediatric and Adult Patients
Recently it has been shown that clear reproducible Doppler signals can be recorded from the lung parenchyma by means of a pulsed Doppler ultrasound system incorporating a special signal processing package parametric Doppler, TPD…

Dyspnea, Acute Decompensated Heart Failure
Evaluation of Cardiopulmonary Diseases by Ultrasound
Historically, ultrasound imaging of the lung parenchyma has been challenging because of the high total ultrasound energy attenuation and scattering by the air in the lungs.
- Trial name
- NCT02248831
- Testing
- Recording Doppler ultrasound signals noninvasively
- Where
- United States
- Volunteers
- 600 people

Cardiac Arrest (CA), Return of Spontaneous Circulation
Pulse Detection in Cardiac Arrest Patients Using a Doppler Ultrasound Patch on the Carotid Artery
The purpose of this study is to find out if a Doppler ultrasound patch placed on the neck can accurately and quickly detect when a cardiac arrest patient's heart starts beating again (return of spontaneous circulation, or ROSC)…
- Conditions
- Cardiac Arrest (CA), Return of Spontaneous Circulation, CPR Quality Assessment
- Trial name
- NCT07729228

Congestive Heart Failure (CHF)
Evaluation of Blood Flow Patterns in Lung Blood Vessels Using Ultrasound Technique in Patients With Congestive Heart Failure
Historically, transthoracic Doppler echocardiography has been unable to provide interpretable data of blood flow within the lung parenchyma because of air attenuation of Doppler signals.
