1, Introduction: The main content of Newman's medical care system model, which mainly includes stressors, physical defense and nursing intervention. When the original pressure is applied to the body, the body will react defensively. The purpose of nursing is to maintain and restore the balance of the body system through nursing intervention.
2. Definition: Newman's health care system model is a comprehensive and dynamic model, which holds that individuals and the environment interact with each other. It is emphasized that man is an open system interacting with the environment and the individual's response to stressors in the environment. The sum of the internal and external environment of environmental organisms, that is, the sum of all internal and external stressors and resistance factors. The concept of autogenous environment is put forward, that is, the general term for the spontaneous change of nursing objects for the integrity and stability of their own systems.
3. Application: When the stressor is suspected, or when the stressor has been confirmed but has not responded, intervene to prevent the stressor from invading or reduce the possibility of its invasion, and strengthen the normal defense of the body. Such as health education, protection of susceptible population and early detection of diseases. Early diagnosis, treatment and nursing measures when the stressor crosses the body's normal defense line and causes symptoms. After secondary prevention, take preventive measures to restore the system balance and return to the state of primary prevention.
