# The Use of Modern Technologies in Post-COVID-19 Cardiopulmonary Rehabilitation
## 5 Patient Monitoring Devices Used at Home in COVID-19 Area  
At this time, home rehabilitation programs use heart rate monitors to measure the heart rate during exercise sessions. Regarding this aspect, a reluctance of patients is reported, and some studies report only 35% of all patients were willing to use such a device at home. The study shows that reluctance does not take into account age, education or background. The study also reports that 68% of patients who did not use a heart rate monitor felt that heart rate monitoring was important during exercise at home. The same study shows that patients are not much more open to the application of modern technologies, reporting a number of 12% of patients who were willing to use a physical activity monitoring system such as counting steps and energy consumption. This monitoring has been made available through smart-watch devices or smartphone applications [50]. The use of digital technology in healthcare has transformed the way we use health data and health information. The Sheba Medical Center in Israel has adopted an application that interfaces with various portable medical devices and patient monitoring devices. In this study, the heart rate, the number of steps as well as the daily use of the application were monitored in correlation with a set of aerobic exercises (min) indicated through the application. Remote heart rehabilitation and heart failure programs using Bluetooth technology have been created and are currently monitoring hundreds of patients remotely, which has helped increase patient satisfaction and helped increase compliance with physical activity, even in the global pandemic context. The progress and tasks assigned to the patient are tracked with the help of the application so that the patient is monitored without having to come to the hospital [51; 52]. The University of Minnesota sought to assess the early lessons of a commitment and how the remote monitoring of patients can be achieved, thus developing a technological solution for patients with symptoms of the COVID-19 disease. Thus, remote monitoring of patients becomes a fast and efficient solution. The program involved patients who were offered educational materials and the opportunity to share their concerns. The development of the platform and the alerts were carried out with the help of some providers of a virtual care platform together with the medical students. They contributed to this platform by providing information about the patients' conditions, monitoring the state of health and the vital parameters. The detection of these data resulted in over 2303 alerts, 4613 messages, 13 hospitalizations and 91 emergency room visits. The period in which the statistics were compiled was between 18 March and 20 April 2020, with 3701 patients enrolled in the program, of whom 2255 (60.93%) had symptoms of COVID-19. This platform (Figure 1) has provided patients with considerable support during the pandemic and of course a safe experience, while reducing COVID-19 exposure and excessive use of medical personnel. In conclusion, it can be highlighted that the remote monitoring of patients is an effective approach to managing the symptoms of COVID-19 at home and alerting medical staff in a very short time [53]. [PERSON] set up a remote monitoring program for patients diagnosed with COVID-19, with the aim of monitoring them after discharge from the hospital [50]. Thus, patients diagnosed with COVID-19 who were discharged from the hospital were selected. They were enrolled in the program and later received an application available for smartphone through which it is possible to record the data from the received pulse oximeter and thermometer. The patients filled in their personal data in the application to automatically report symptoms as well as O\({}_{2}\) saturation and temperature at the end of each day. Abnormal symptoms or vital signs that do not meet the optimal parameters are evaluated by medical staff. Descriptive statistics were used to describe the characteristics of the patient and the program.
