The Neuman Systems Model is a conceptual framework developed by Betty Neuman that focuses on the holistic approach to patient care. It emphasizes the importance of understanding the individual as a whole, considering physical, psychological, social, and spiritual factors. The model illustrates how stressors can impact a person's health and well-being, highlighting the need for preventive measures. In this model, the individual is viewed as a system with various layers of defense against stressors. These layers include the internal environment (personal factors) and the external environment (community and societal influences). The goal is to maintain optimal health by addressing these stressors and promoting resilience.
