Valsalva manoeuvre can be used to study baroreflex sensitivity in pregnancy

Objective: The aim of this study was to assess whether baroreflex sensitivity can be measured in a non-invasive manner with the Valsalva manoeuvre in pregnancy. Study design: Baroreflex sensitivity was measured from the reflex response to phenylephrine injection and phase four of the Valsalva manoeu...

Zusammenfassung:	Objective: The aim of this study was to assess whether baroreflex sensitivity can be measured in a non-invasive manner with the Valsalva manoeuvre in pregnancy. Study design: Baroreflex sensitivity was measured from the reflex response to phenylephrine injection and phase four of the Valsalva manoeuvre in nine pregnant women at 27 (range 24–33) gestational weeks. Results: Both the phenylephrine test and the Valsalva manoeuvre yielded similar estimates of baroreflex sensitivity (9.3 (4.1) ms/mmHg vs. 8.0 (5.2) ms/mmHg, Pearson's correlation coefficient r=0.81, P
