ClinConnect Summary

This clinical trial is studying a new way to measure blood pressure in pregnant women, especially those who are overweight or obese. It compares two types of blood pressure cuffs: a conical cuff that fits the forearm and a cylindrical cuff that fits the upper arm. The goal is to see if the conical cuff can provide more accurate blood pressure readings. Accurate blood pressure measurement is very important during pregnancy because high blood pressure can lead to serious conditions like gestational hypertension or preeclampsia. If the conical cuff is proven to be more reliable, it could help doctors make better decisions about treatment, reducing unnecessary interventions like early delivery or cesarean sections.

Women who are 18 years or older and have a body mass index (BMI) of 20 or higher may be eligible to participate. They should be coming to the hospital for labor and delivery, whether or not they have been diagnosed with high blood pressure during pregnancy. Participants will have their blood pressure measured using both types of cuffs, and the researchers will compare the results to see how well they match. This trial aims to improve care for the many pregnant women facing these health challenges, making it easier for doctors to manage their pregnancies safely.
