Assessing Innovative Wireless and Wearable Sensors for Continuous Blood Pressure Measurement in Obese Pregnant Women

Assessing Innovative Wireless and Wearable Sensors for Continuous Blood Pressure Measurement in Obese and Super-obese Pregnant Women

This study is a prospective study targeting at least 20 obese and super-obese patients admitted to Labor & Delivery (L&D) for delivery at UNC Medical Center. Patients with clinical indicated radial A-lines either planned or already in-situ will be offered participation. The study will evaluate the accuracy of noninvasive blood pressure measurements with the ANNE One system to blood pressure readings with the radial A-line.

Inclusion Criteria:

• Age >= 18 years old
• Ability and willingness to provide written informed consent
• Admitted for delivery at UNC Medical Center
• BMI of >= 40 kg/m2
• Clinically indicated radial A-lines either planned or already in-situ prior to delivery

Exclusion Criteria:

• Skin sensitivity or allergy that precludes placement of ANNE One
• Any condition (social or medical) which, in the opinion of the study staff would make any study participation unsafe or complicate data interpretation
• Expected delivery within <= 1 hour of arrival to L&D
