This study utilizes physiological indicators of COVID-19 patients, such as blood pressure, heart rate, respiratory rate, and level of consciousness, to develop Shock Index (SI), Mordified Shock Index (MSI), Age Shock Index (Age SI), Age Mordified Shock Index (Age MSI), and Respiratory Adjusted Shock Index (RASI), as well as other physiological indicators, as tools for assessing, tracking, worsening, and improving the clinical symptoms of COVID-19 patients. For patients with mild to severe illness, and in response to the shortage of manpower during a large influx of emergency patients, this study employs simple and easy-to-use assessment methods, which can be further aided by artificial intelligence technology to facilitate early response and medication.
