Patient monitoring is the continuous or periodic assessment of a patient's physiological parameters, such as heart rate, blood pressure, respiratory rate, and temperature, to detect any changes that may indicate a deterioration in their health status. This monitoring can be done in various healthcare settings, including hospitals, clinics, and even at home using wearable devices. The data collected through patient monitoring helps healthcare providers make informed decisions about the patient's care and treatment plan. Advances in technology, such as remote monitoring and telemedicine, have made patient monitoring more accessible and convenient for both patients and healthcare providers.
