Background:
Hypertension in pregnancy in the developing world is largely underreported, misdiagnosed, and untreated, especially in rural settings, though it contributes significantly to maternal and perinatal morbidity and mortality. To reduce general global cardiovascular and cerebrovascular morbidity and mortality, the World Health Organization aims to develop and validate low-resource-use blood pressure devices for use in developing nations.
Objective And Methods:
To describe how existing antenatal care systems provide a useful and relevant model through which to evaluate the potential for this initiative to be applied in low-resource settings and to offer opportunities for much needed further research.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Pre-Procedural Guidelines for Assessing Blood Pressure
Special considerations while measuring blood pressure
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.
