This course introduces the respiratory-circulatory model of osteopathic treatment as a holistic approach based on principles highlighted by J. Gordon Zink and others. The primary goal is to provide a clinical model that enables efficient assessment and treatment of the body to improve patients’ respiratory capacity, pressure gradient fluctuations in body cavities, and the movement of tissues and body fluids. Upon completion of the course, participants should be able to apply this approach immediately in their clinical practice.
