Vital Signs and Sensors for Post-Exertional Malaise Prevention

Abstract

Post-exertional malaise (PEM) is the core symptom of Chronic Fatigue Syndrome / Myalgic Encephalomyelitis, a disease that can break out after surviving a SARS-CoV-2 infection. Multiple types of triggers lead to an extremal deterioration of the patient's overall health condition. In this paper, vital signs are compared to what extent they are sensitive to the triggers and thus can be used to prevent PEM. In addition, sensors and measurement methods are proposed, based on criteria for use in patients' daily lives. Even simple pedometers can contribute to PEM prevention. However, chest straps and wrist-worn sensors are more promising. The essential relevant vital parameters heart rate, blood pressure and respiratory rate are measured in this way.
