Field hospitals are temporary medical facilities set up in response to emergencies, such as natural disasters or military conflicts. They provide essential medical care, including triage, surgery, and rehabilitation, often in locations where traditional hospitals are unavailable or overwhelmed. These hospitals are equipped with necessary supplies and staffed by healthcare professionals to treat patients quickly and efficiently. Typically, field hospitals are designed to be mobile and can be established in various environments, such as tents or converted buildings. They play a crucial role in disaster response, helping to manage large numbers of patients and ensuring that medical care reaches those in need, especially in crisis situations like Hurricane Katrina or military operations.
