Patient monitoring devices are tools used in healthcare to track a patient's vital signs and overall health status. These devices can measure parameters such as heart rate, blood pressure, oxygen levels, and temperature. They help healthcare professionals detect any changes in a patient's condition, allowing for timely interventions. Common types of patient monitoring devices include electrocardiograms (ECGs), pulse oximeters, and blood pressure monitors. Many of these devices can be used in hospitals, clinics, or even at home, providing continuous data that supports better patient care and management.
