About the study: Hypertensive disorders of pregnancy such as preeclampsia increase the risk of life-ending and life-altering complications for both the mother and her unborn baby. Oxygen levels in pregnant women are measured using a non-invasive and safe machine called the pulse oximeter to measure hypertension. The oxygen level is measured by placing a probe on a woman’s finger for one minute, and the information collected through this method is used for patient monitoring and diagnosis of pregnancy-related complications.

This research study is being done because, at present, there are no guidelines outlining the best finger to use for measuring the oxygen saturation in the blood in pregnant women. It might be that different fingers of the hand provide different quality of information, and it is important to identify which finger provides the highest quality of information so that clinicians can make more accurate diagnoses. Signal patterns will also be looked at to see if it is predictive of pregnancy outcomes.

Why is this research important? Collecting high-quality signals from the most appropriate finger will enhance current care models by helping clinicians make a more accurate diagnosis, improve early prediction of complications, and enable timely patient management in health care settings and around the world where this technology is used.

Study status: Recruiting, aim to recruit 200 women.

Who can participate? For this study, we will recruit women who have no hypertension and those who have hypertension developed during pregnancy. These women will be compared in the data analysis, and will also be looked at according to how many weeks gestation they are. You may be able to participate in this study if:
• You are pregnant at 20–40 weeks gestation
• You are 20 years of age or older
• You have a singleton pregnancy
• You are delivering at BC Women’s Hospital

The Women’s Health Research Institute would like to acknowledge that we are uninvited guests on the unceded ancestral territories of the xʷməθkwəy̓əm (Musqueam), Skwxwú7mesh (Squamish), Stó:lo, and sel̓íl̓witulh (Tsleil-waututh) Nations.

As a provincial research institute committed to improving the health outcomes of women, including those across the 2SLGBTQIA+ spectrum, we recognize our responsibility in the collective effort towards establishing culturally safe health care systems and services that address health inequities among Indigenous peoples, especially Indigenous women, girls, and Two-spirit peoples.

We encourage all people involved in research to read both the Truth and Reconciliation Commission of Canada: Calls to Action and the In Plain Sight Report, and reflect on ways we can incorporate the recommendations into our work. As we gather in spaces together, we encourage you to reflect on your positionality on these lands and your personal commitments to reconciliation.
