Pulmonary Blood Flow Measurements in CHF Patients

Stopped early

Conditions studied: Congestive Heart Failure (CHF)

In brief

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. Recently, a transthoracic Doppler system known as the Sonara/tek Transcranial Doppler (TCD) System has been developed that can identify parenchymal pulmonary blood flow (PPBF) signals. The ability to non-invasively collect information regarding the pulmonary aspect of the cardio-pulmonary system may provide valuable information and new insights into the structural and functional characteristics of the lung parenchyma and vasculature in health and disease states.
