Fig. 3: MDRL per variable.
From: A scoping review on advancements in noninvasive wearable technology for heart failure management
An overview of the variables utilized in various wearables in research for heart failure remote monitoring. For each variable, the Medical Device Readiness Level (MDRL) is provided. MDRL medical device readiness level, HF heart failure, SpO2 blood oxygen saturation, VO2 Oxygen uptake. MDRL presented in the figure represents the highest MDRL of that variable. Figure created using BioRender.
