The research team has developed an automatic blood pressure monitor (Sphygmo) to be used for the monitoring and diagnosis of pre-eclampsia in pregnant women, particularly in low-resource settings where current monitoring is limited. 90 adult volunteers will be enrolled by researchers at Rice University. The participant will be seated in a comfortable chair with arm at heart level. Arm circumference will be measured and a blood pressure cuff will be placed on the arm. The cuff will be inflated and blood pressure measurements will be taken by a commercially available device and by the Sphygmo device. Blood pressure measurements from both devices will be recorded. The participant's blood pressure will be measured up to 9 times with a waiting period of 45-60 seconds between each measurement. The results of this study will be used to optimize the blood pressure detection algorithm and thus further develop the device.

Accuracy of Blood Pressure Measurement by Sphygmo Relative to the Clinical Standard.
Timeframe: Blood pressure was measured an average of 9 times for each participant during their single visit and the mean of these measurements was recorded and used for analysis. The measurement period lasted approximately 30-45 minutes.
Percentage of Sphygmo Readings That Were With < 5 mmHg, < 10 mmHg, and < 15 mmHg of the Readings by the Gold Standard Sphygmomanometer.
