﹤Biotech & Biomed Innovation﹥AI-Based Non-Invasive Continuous Arterial Pressure Waveform Prediction System

Kaohsiung Medical University / Prof. Kuang-I Cheng

 Pain Points Solved 

  • Conventional continuous arterial pressure monitoring requires arterial catheterization, which is invasive and carries a risk of infection.
  • Existing blood pressure waveform prediction techniques are often limited by prediction latency and insufficient accuracy, making them unsuitable for real-time clinical applications.
  • Clinical physiological monitoring devices are complex to operate, increasing the workload of medical staff as well as personnel and consumable costs.

 Technology Introduction 

This invention utilizes a composite model based on a temporal convolutional neural network (TCN) to compute and generate continuous arterial pressure waveforms within a 1-second future window using electrocardiogram (ECG) waveforms, blood oxygen saturation (SpO₂) waveforms, and physiological data. The system’s predictions comply with the standards set by the British Hypertension Society (BHS) and the Association for the Advancement of Medical Instrumentation (AAMI). It can be applied for real-time monitoring of continuous arterial blood pressure during surgeries or in critical care settings. The system offers advantages such as non-invasiveness, reduced risk of blood infections, decreased medical personnel and consumables, and improved patient comfort during treatment.
