Is the supine pressor test an adequate means of predicting acute hypertension in pregnancy?
The supine pressor test was performed on 207 nulliparous young women between the twenty-eighth and thirty-second weeks of gestation. The supine pressor test predicted pregnancy-induced hypertension in 78 per cent of those women who subsequently developed the condition. Ninety-six per cent of the women who failed to demonstrate a rise in diastolic pressure on position change remained normotensive throughout the remainder of the pregnancy.

The Brachial Artery: Primary Site for Blood Pressure Measurement
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...
Assessment of blood pressure in brachial artery(two-step method)
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.
