Life support systems are essential technologies that provide the necessary conditions for life in environments where natural support is absent or insufficient. These systems are commonly used in space missions, underwater exploration, and medical settings. They typically include components that supply oxygen, remove carbon dioxide, and regulate temperature and humidity. In medical contexts, life support systems can refer to equipment that maintains vital functions for patients who are critically ill or injured. Examples include ventilators, which assist with breathing, and dialysis machines, which perform the functions of the kidneys. These systems are crucial for sustaining life until recovery or further medical intervention can occur.
