About

The purpose of the study is to collect per subject blood pressure data on the device's intended population as described in the International Organization for Standardization (ISO) Standard 81060-2:2018+A1:2020 Non-invasive sphygmomanometers.

Full description

The purpose of the study is to collect data per subject NIBP measurements by (1) oscillometric means using the GE NIBP Auscultatory Algorithm and (2) by conventional auscultatory means in a pregnant population. These measurements include Systolic BP (mmHg) and Diastolic BP (mmHg). The secondary objective of this study is to collect per procedure and log files from the device. The safety objective of this study is to collect safety information, including type and number of adverse events, serious adverse events and device issues.

This is an open label, single-site, single arm, prospective, pivotal study including a training phase and a validation phase with demographics-based stratification quota. Subjects are sequentially tested with investigational and reference blood pressure measurements.

Enrollment: 170 estimated patients

Sex: Female

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

Are pregnant female volunteers aged 18 years or older;

Gestation beyond the first trimester as evidenced by gestational age of greater than or equal to 14 weeks and 0 days;

Have compatible anatomy to fit a standard air-filled occlusive cuff size (an upper limb circumference ranging 17 cm to 40 cm);

Are willing and able to volunteer to provide multiple blood pressure measurements as required for study procedures;

Are able and willing to provide written informed consent.

Exclusion criteria

Exhibit signs or symptoms or have a current diagnosis of peripheral vascular disease;

Have current, uncontrolled circulatory shock or cardiac arrhythmias that pose risk to the patient or could interfere with completion of study blood pressure determinations;

Exhibit injuries, deformities, intravenous lines, or other abnormalities that, in the opinion of the investigator, may prevent proper occlusive cuff application or functioning; the investigator, may prevent proper occlusive cuff application or functioning;

Have contraindications to blood pressure measurement methods used in the study or any medical condition where study procedures could pose a risk to the subject/patient's physiological stability, in the opinion of a medically qualified investigator.
