Background

Cardiovascular diseases are globally recognized as one of the leading causes of death. Hypertension stands out as a significant risk factor for their development, and targeted treatment can effectively reduce the risk of cardiovascular complications. Nowadays, blood pressure measurements are primarily conducted using one of two methods: non-invasive measurement using a cuff placed around the upper arm, or invasive measurement in the arterial line. However, neither of these methods is suitable for continuous blood pressure monitoring in regular hospital wards or during home rehabilitation. The technique of digital PPG (PhotoPlethysMography) shows promising results in this regard.
