Special Issue Information

Dear Colleagues,

Biomedical signal processing is a rapidly advancing field that plays a pivotal role in healthcare, with the latest advances focusing on the integration of artificial intelligence and machine learning to enhance data analysis and clinical decision-making. The incorporation of intelligent methods in biomedical engineering facilitates the extraction, classification, and optimization of clinical information from vast medical datasets, significantly easing the workload of medical staff and providing effective feedback for clinicians as decision-making systems. Advancements in healthcare sensors and remote measurement tools have enabled continuous monitoring, which is crucial for timely intervention and has expanded into non-medical areas such as fitness and well-being.

The future of biomedical signal processing lies in the ability to analyze complex physiological systems as a whole, using network medicine approaches to understand the structure of diseases better. Biomedical signal processing in healthcare is evolving with a strong focus on intelligent systems that can process and analyze vast amounts of data to support clinical decisions, improve patient care, and open new avenues for research and development.

Recommended topics include, but are not limited to, the following:

  1. Integration of AI and Machine Learning.
  2. Wearable Technology for Continuous Health Monitoring.
  3. Big Data in Healthcare.
  4. Improvement of Signal Processing Techniques.
  5. Personalized Medicine.
  6. Remote Patient Monitoring.
  7. Non-invasive Diagnostic Tools.
  8. Smart Alert Systems.
  9. Data Privacy and Security.
  10. Ethical Considerations in Healthcare Technology.

We provide new insights into the performance of camera-based heart and respiration rate extraction and evaluate its usability for replacing spot checks conducted in the general ward. A study was performed comprising of 36 ICU patients recorded for a total time of 699 h. The 5 beats/minute agreement between camera and ECG-based heart rate measurements was 81.5%, with a coverage of 81.9%, where the largest gap between measurements was 239 min. The challenges encountered in heart rate monitoring were limited visibility of the patient’s face and irregular heart rates, which led to poor agreement between camera- and ECG-based heart rate measurements. To prevent non-breathing motion from causing error in respiration rate extraction, we developed a metric which was used to detect non-breathing motion. The 3 breaths/minute agreement between the camera- and contact-based respiration rate measurements was 91.1%, with a coverage of 59.1%, where the largest gap between measurements was 114 min. Encountered challenges were the morphology of the respiration signal and irregular breathing. While a few challenges need to be overcome, the results show promise for the usability of camera-based heart and respiration rate monitoring as a replacement for spot checks of these vital parameters conducted in the general ward.
