Patient monitoring refers to the continuous observation of a patient's vital signs and overall health status. This process often involves the use of medical devices to track parameters such as heart rate, blood pressure, and oxygen levels. By collecting this data, healthcare providers can quickly identify any changes in a patient's condition and respond accordingly. In hospitals, patient monitoring is crucial for those in critical care settings, such as the intensive care unit (ICU). Advanced monitoring systems can alert medical staff to potential issues, ensuring timely interventions. This practice enhances patient safety and improves outcomes by allowing for proactive management of health concerns.
