Special Issue Information

Dear Colleagues,

We seek contributions that cover topics studying the implementation of electrical bioimpedance-based sensors and sensing methods in medicine and related disciplines.

The study of electrical bioimpedance has been widely discussed and covered; however, it is still too early to talk about the wide-scale use of the electrical bioimpedance method in medical practice. The possibilities are certainly much wider than the implementation, for example, of wearable devices for the continuous monitoring of patients both in hospital care and home follow-up treatment. It is important that significant improvements in treatment quality and an increase in patient safety during hospitalization are made possible.

In this Special Issue, we welcome publications on new research, development work, inventions and practical implementations of bioimpedance methods both in clinical research and practice, as well as disease prevention and follow-up treatment in all branches of medicine.

Repeated single-point measurements of thoracic bioimpedance at a single (low) frequency are strongly related to fluid changes during hemodialysis. Extension to semi-continuous measurements may provide longitudinal details in the time pattern of the bioimpedance signal, and multi-frequency measurements may add in-depth information on the distribution between intra- and extracellular fluid. This study aimed to investigate the feasibility of semi-continuous multi-frequency thoracic bioimpedance measurements by a wearable device in hemodialysis patients. Therefore, thoracic bioimpedance was recorded semi-continuously (i.e., every ten minutes) at nine frequencies (8–160 kHz) in 68 patients during two consecutive hemodialysis sessions, complemented by a single-point measurement at home in-between both sessions. On average, the resistance signals increased during both hemodialysis sessions and decreased during the interdialytic interval. The increase during dialysis was larger at 8 kHz (∆ 32.6 Ω during session 1 and ∆ 10 Ω during session 2), compared to 160 kHz (∆ 29.5 Ω during session 1 and ∆ 5.1 Ω during session 2). Whereas the resistance at 8 kHz showed a linear time pattern, the evolution of the resistance at 160 kHz was significantly different (p < 0.0001). Measuring bioimpedance semi-continuously and with a multi-frequency current is a major step forward in the understanding of fluid dynamics in hemodialysis patients. This study paves the road towards remote fluid monitoring. Full article
