MEDICAL TECHNOLOGY FOR INNOVATIVE DIAGNOSTICS

CARDIOLOGY

Nocturnal blood pressure has a very high diagnostic significance. When recording physiological signals in sleep medicine, we noticed that the usual 24-hour blood pressure cuff recording technique (Riva Rocci) has little informative value for nocturnal blood pressure. This method was designed for day-time blood pressure measurement while sitting upright with the cuff placed at the same level as your heart. For nocturnal measurements however, artifacts occur due to changing hydrostatic pressure caused by body position changes and arousal reactions that can happen after the inflation of the cuff. In addition, blood pressure fluctuations will not be recognized/recorded  because of limited measurement (normally only two readings per hour). These artifacts as well as the missing values lead to the wrong estimation of nocturnal blood pressure.

SOMNOmedics has recognized this issue, and developed a method for non-invasive, reaction less, continuous blood pressure determination, without a cuff, based on PTT (Pulse Transit Time). This unique, patented* and validated** method allows you to provide a reliable picture of the nocturnal systolic and diastolic blood pressure with true minima and maxima values. This innovative method is available, as an option, for all SOMNOmedics products.

For cardiological applications we provide a sophisticated and powerful All-in-One product, which simultaneously records Holter ECG, oximetry, actigraphy and pulse wave velocity – as a measure of arterial stiffness – in addition to continuous long-term blood pressure. This increases the diagnostic accuracy and optimizes reimbursement options.
