Measuring Blood Pressure in Pregnant Women Using Different Cuffs
Evaluation of the Agreement Between Conical Forearm and Cylindrical Upper Arm Non-Invasive Blood Pressure (NIBP) Measurements in Pregnant Patients
NA · Northwestern University · NCT06466161
This study is testing if a special forearm cuff gives more accurate blood pressure readings for pregnant women compared to a regular upper arm cuff, especially for those who are very overweight.

What this trial studies
This study evaluates the accuracy of blood pressure measurements in pregnant women using two different types of cuffs: a cylindrical cuff for the upper arm and a conical cuff for the forearm. Participants will be categorized into four groups based on their blood pressure and obesity status. The goal is to determine if the conical cuff provides more accurate readings, especially in morbidly obese patients, which could lead to better diagnosis and management of hypertension during pregnancy. Measurements will be taken while participants are seated, and various arm and forearm dimensions will be recorded to ensure proper cuff fitting.
Who should consider this trial
Good fit: Ideal candidates are pregnant women aged 18 and older with a BMI of 20 kg/m² or greater, presenting with or without a diagnosis of hypertension.
Not a fit: Patients with significant peripheral arterial disease or a history of certain heart conditions may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to more accurate blood pressure readings in pregnant women, reducing unnecessary treatments and complications.
How similar studies have performed: Other studies have indicated that improved cuff designs can enhance blood pressure measurement accuracy, suggesting potential success for this approach.
