In health care, which technology is used to monitor patients remotely?

The selection of online patient-monitoring systems aligns with the advancements and implementation of telehealth technologies in the healthcare industry. These systems allow healthcare providers to track patient health metrics and conditions from a distance, enhancing the ability to provide timely medical care. By using these technologies, healthcare professionals can monitor vital signs, manage chronic conditions, and even engage with patients for follow-up care without requiring them to come into the facility, thereby improving accessibility and convenience.

Moreover, online patient-monitoring systems utilize various devices such as wearable sensors and mobile health applications, facilitating real-time data transfer for better decision-making. This is particularly valuable in managing patients with chronic diseases or those recovering from surgery, as it allows for continuous oversight and immediate responses if the patient’s condition changes. This proactive approach can lead to improved outcomes and reduced hospital readmission rates.

In contrast, the other options do not pertain to patient monitoring. Online newspapers provide information and news but are unrelated to health monitoring systems. Debit cards and point-of-sale systems are financial tools used in retail environments and have no application in health monitoring. Therefore, online patient-monitoring systems are distinctly relevant and essential in modern healthcare for remote patient supervision.
