Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Blood volume measurements are a critical step in the emergency care of trauma patients. The typical approach to this is to rely on historical information, physical examination and metrics such as heart rate. There is currently no good real-time measure to track blood volume. This study investigates the use of phonocardiography (listening to the sounds made by the heart) to track changes in central blood volume.
