A vital signs monitor is an essential medical device that continuously measures key health parameters including blood pressure, heart rate, oxygen saturation (SpO₂), and often body temperature and respiratory rate. It provides real-time data that allows healthcare providers to track a patient’s overall physiological status, detect early signs of deterioration, and respond promptly to emergencies. Widely used in clinics, hospitals, and critical care settings, these monitors help ensure patient safety, guide treatment decisions, and support efficient management of both acute and chronic conditions.
