Vital signs such as pulse, heart rate, respiration rate, temperature reflect body’s functional status. Their continuous monitoring is needed to detect the critical changes in patients’ health status and to guide the timely interventions, especially for Intensive Care Unit (ICU) patients. This becomes a challenge in facilities with insufficient staff, equipment. The use of low-cost wearable devices, powered by advanced sensor technology can address such issues associated with continuous monitoring in resource-limited low-income settings.
Wearable devices can be planted on a patient’s body to track the vital sign changes in real-time and can send and receive the data via the internet. A recent study has demonstrated the feasibility of such wearable devices in obtaining continuous photoplethysmography and ECG data from Vietnamese ICU patients. The heart rate variability parameters, SpO 2…
