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. These devices can be found in hospitals, clinics, and even at home. Examples include heart rate monitors, pulse oximeters, and blood pressure cuffs. By providing real-time data, patient monitoring devices play a crucial role in ensuring patient safety and improving the quality of care.
