Patient monitoring systems are medical devices that continuously observe a patient's vital signs, such as heart rate, blood pressure, and oxygen levels. These systems can be used in hospitals, clinics, or at home, providing real-time data to healthcare professionals. This information helps in making timely decisions regarding patient care and treatment. These systems often include sensors and alarms that alert medical staff if a patient's condition deteriorates. By using telemetry and wireless technology, patient monitoring systems can transmit data to a central monitoring station, allowing for efficient oversight and improved patient outcomes.
