developing continuous Blood Pressure monitoring with viQtor: Catharina Eindhoven


collaboration with: Catharina Hospital Eindhoven (CZE)

Heart failure management and perioperative care require comprehensive, continuous monitoring of vital signs to ensure timely intervention and optimal patient outcomes. The Catharina Eindhoven - Pressure Study represents a crucial step in enhancing viQtor’s capabilities by introducing non-invasive, continuous blood pressure (BP) measurement through advanced PPG-based technology. This study will provide the foundation for a groundbreaking innovation in patient monitoring, further supporting our mission to deliver real-time health insights for proactive care.

study overview & objective

The Pressure Study is a prospective data-collection study focused on developing, optimizing, and verifying the technical performance of a new PPG-based algorithm for continuous BP measurement within the viQtor device. Conducted in collaboration with Catharina Hospital Eindhoven, the study involves collecting raw PPG data and vital signs—blood pressure, heart rate, respiratory rate, and SpO2—from perioperative ICU patients. The study aims to develop and validate a continuous BP measurement algorithm based on PPG data collected by viQtor. Data will be gathered from multiple sources, including the viQtor research device, an ear pulse oximeter, and an invasive arterial line, ensuring comprehensive and accurate input for algorithm development. The gathered data will undergo extensive analysis using machine learning techniques and manual feature assessment by the research team.
