KG SOMNOcheck micro 2009 9 Risk for sleep disturbance u The risk is shown by simple RAG rating u Risk Level: LOW, MEDIUM, HIGH (Green, Amber, Red) u Evaluation of risk: • The recorded parameters Apnea/Hypopnea-Index (AHI/RDI) and Autonomous Arousal-Index (AAI) define the risk. • The concept of „worst case“ is used. AHI / RDI < 10/h AAI < 30/h AHI / RDI 10 – 15/h AAI 30 - 40/h AHI / RDI >= 15/h AAI >= 40/h

The procedure is already known from pulse oxymetrie. u Pulse waves are affected by: • Rhythm (heart rate), Regularity (changes or stability of frequency), Blood vessel filling, Amplitude, Slew rate (shape of the curve), Dikrotie (second peak of the peripheral pulse wave), Stiffnes (duris or mollis) u Respiratory events and arousals induce characteristic changes in the pulse wave. Although the intrathoracic pressure changes are minor, the effect is consistently seen in a peripheral pulse trace. u With an innovative algorithm and the characteristics of the pulse trace it is possible to detect the events. Characteristics of pulse wave Volume u A distinction between obstructive and central events is also realised in SOMNOcheck micro. This is a very good option for disease-specific referral.
