Researchers from Kaunas University of Technology (KTU) in Lithuania have discovered that low-frequency ultrasound can significantly influence blood parameters, particularly improving oxygen transfer from the lungs to tissues. The study, conducted on 300 blood samples from 42 pulmonary patients, examined the effects of six different low-frequency ultrasound modes using advanced equipment at KTU’s Institute of Mechatronics and the Lithuanian University of Health Sciences (LSMU).
The findings revealed that ultrasound affects red blood cells (RBCs) by dissociating aggregated cells into single RBCs, enhancing their hemoglobin’s interaction with oxygen. This process increases oxygen saturation and reduces blood viscosity, leading to improved circulation and lower blood pressure. These results were supported by molecular analysis conducted at LSMU’s Laboratory of Molecular Cardiology, highlighting the potential benefits for patients with pulmonary hypertension or related conditions.
The research also explored how ultrasound could serve as a non-pharmaceutical approach to improving oxygen circulation. Unlike high-frequency ultrasound, which primarily affects external tissues, low-frequency waves penetrate deeper into internal organs, offering more uniform sound pressure distribution. This characteristic opens new possibilities for therapeutic applications, such as enhancing oxygen delivery or aiding medication activation.
The interdisciplinary collaboration between engineers and medical professionals at KTU exemplifies the potential of merging expertise. This partnership has previously led to innovative medical solutions, including devices for radiosurgery. The researchers envision further exploring ultrasound technology’s capabilities, particularly in the context of pulmonary health and post-COVID-19 treatments. With its ability to improve oxygen transfer and reduce blood pressure, low-frequency ultrasound could emerge as a transformative tool in modern medicine, offering non-invasive alternatives to traditional treatments.
