As a most wanted intensive care equipment for life support, Ventilators support the breathing process of critically ill patients who had lost the ability to breathe on their own. Their main functions include getting oxygen into the lungs and removing carbon dioxide from the body, aiding the respiration process. They are often used for short periods, such as during a surgery. It helps to make sure that the patient continues breathing during critical surgeries. Some patients may need to use ventilators long term or for the rest of their lives. Such ventilators are compatible even outside the hospital, i.e., in care facilities or at home.
Portable Ventilators are lightweight and can be moved easily from one place to another within the hospital. They are able to function in demanding environments with little maintenance. They provide long-term support for patients who do not require complex critical care ventilators. Typically, these portable ventilators drive air into the breathing circuit with a motor-driven piston or a turbine. In the home setting, O2 is usually delivered directly into the breathing circuit from a separate source, such as an O2 tank.
Modern Ventilator Systems are electronically controlled by a small embedded system to allow required adaptation of pressure and flow characteristics based on the needs of a patient. Fine-tuned ventilator settings also serve to make ventilation more tolerable and comfortable for the patient. Ventilator Systems are classified as a life-critical system, and necessary precautions are taken in to ensure that mechanical ventilation systems are highly reliable.
