The SANDY Study - Postpartum Health Monitoring
The SANDY (Study Assessing Norms and Determinants of post-pregnancY vitals) study
aims to better understand blood pressure, heart rate, and oxygen saturation in mothers during
the postpartum period (4th Trimester). We are studying natural changes in blood pressure in the
first 42 days after delivery, and your participation could help shape future care standards for
postpartum moms.

You will take biweekly blood pressure readings, heart rate, and oxygen saturation (if applicable)
for 6 weeks after your hospital discharge.
● When to Submit:
○ Every Tuesday and Saturday for 6 weeks.

Frequently Asked Questions
What is the purpose of the SANDY Study?

You will take your blood pressure, heart rate, and (if applicable) oxygen saturation twice a week (on Tuesdays and Saturdays) for 6 weeks after your discharge from the hospital. You will report your vitals to your OB provider if you have concerns and submit them to the research team at
the end of the 6-week period.
How do I submit my vital signs?
At the end of the 6-week period, you will email your completed reporting form to Sahana Narayan.
