Patient monitoring refers to the continuous observation of a patient's health status, often using various medical devices and technologies. This process helps healthcare professionals track vital signs such as heart rate, blood pressure, and oxygen levels. By closely monitoring these indicators, doctors and nurses can quickly identify any changes in a patient's condition and respond appropriately, ensuring timely care. In hospitals, patient monitoring systems are commonly used in intensive care units and during surgery. These systems can alert medical staff to any abnormalities, allowing for immediate intervention. Overall, effective patient monitoring is crucial for improving patient outcomes and enhancing safety in healthcare settings.
