PTT Validations (PULSE TRANSIT TIME) VALIDATION ACCORDING TO THE ESH-IP 2010 PROTOCOL AGAINST CUFF-BASED METHOD DURING ERGOMETRY AGAINST CUFF-BASED METHOD OVER 24 HOURS AGAINST CUFF-BASED METHOD DURING CPAP THERAPY AGAINST THE PENAZ METHOD AGAINST INTRA-ARTERIAL BP MEASUREMENT ® SOMNOtouchTM NIBP is listed on the dabl Educational Trust website as a recommended device

PTT VALIDATIONS (PULSE TRANSIT TIME) Table 1 Validation results * two out of three required for the first threshold; three out of three required for the second threshold ** number of subjects with two out of three differences < 5mmHg *** number of subjects with none of the differences < 5mmHg We have validated our patented* PTT technique against other current methods as described below: Validation of the Somnotouch-NIBP noninvasive continuous blood pressure monitor according to the European Society of Hypertension International Protocol revision 2010.

SOMNOmedics uses an innovative patented algorithm to measure blood pressure via the Pulse Transit Time (PTT). The PTT is the time required for the pulse wave to propagate along the vessel wall between two defi ned points. In the case of the SOMNOtouchTM NIBP – from the left ventricle of the heart (defi ned by the ´R´peak of the ECG) – to the fi ngertip (detected by the plethysmograph). Taking a one point calibration at the beginning of the measurement allows us to `set` the software‘s algorithm – and measure blood pressure continuously throughout the day and night. Because every single pulse...
