Ventilators are medical devices that help people breathe by assisting or taking over the function of the lungs. They are commonly used in intensive care units (ICUs) to support patients who are unable to breathe on their own due to a variety of medical conditions, such as respiratory failure, pneumonia, or acute respiratory distress syndrome (ARDS).
A ventilator works by delivering oxygen-rich air to the patient's lungs through a breathing tube that is inserted into the trachea (windpipe). The machine can be programmed to control the volume, rate, and pressure of the air delivered to the patient, depending on their specific medical needs.
Ventilators are complex machines that require specialized training to operate and monitor. They are a crucial component of critical care medicine and are used to support patients in a variety of medical settings, including hospitals, ambulances, and during surgical procedures.
