The respiratory/circulatory model focuses on improving breathing mechanics and venous/lymphatic circulation to enhance tissue oxygenation and drainage. This is especially important in pregnancy because the body undergoes major cardiopulmonary adaptations: the growing uterus raises the diaphragm and alters chest wall mechanics, tidal volume and blood volume increase, oxygen demand rises, and venous return can be hindered by uterine pressure and pelvic venous stasis. Techniques that improve diaphragmatic motion, rib mobility, and lymphatic drainage help boost uteroplacental perfusion, ease dyspnea, reduce edema, and relieve back or pelvic discomfort. While other patients can benefit, these pregnancy-related changes make the respiratory/circulatory approach particularly impactful.
