Abstract
Twentynine patients with chronic heart failure HF 27 male 705 ± 99 years and nocturnal Cheyne–Stokes respiration were noninvasively ventilated for one hour using adaptive servoventilation ASV therapy PaceWave™ ResMed BP was measured using two devices oscillometrically via Task Force Monitor™ CNSystems and PTT via SOMNOscreen™ Somnomedics at least every 7 min for 30 min before during and after ASVMean systolic BP was 1181 ± 144 mmHg vs 1159 ± 141 mmHg for oscillometric method vs PTT respectively Corresponding values for diastolic BP were 723 ± 103 mmHg and 694 ± 111 mmHg While clinically comparable differences between the two methods were statistically significant p 005 The difference between the two methods showed an increasing trend over time A total of 185 of PTTbased measurements could not be analyzed The direction of a change in BP was opposite for PTT vs oscillometry for 170 and 328 of systolic and diastolic BP measurements respectively
