The maintenance of a stable baseline in intra-uterine pressure with varying maternal position--a practical approach
Abstract:
When measuring intra-uterine pressure, the tracing baseline varies according to maternal position because of changes in hydrostatic pressure. To compensate for this effect, the membrane of the transducer should always be kept close to the uterine fundus. An additional advantage of this method is that it enables the use of a short catheter, thus causing less tracing artifacts.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
