Postpartum hemorrhage is a well-known complication of delivery and the leading cause of maternal mortality worldwide. In developed nations, a complete blood count (CBC) is commonly collected as a means to assess or base treatment for blood loss. The Hemi device is a point-of-care device designed to provide hematocrit, followed by the stage of hemorrhagic shock using artificial intelligence algorithms. The ultimate goal of the product is to provide an accurate hematocrit from easily attainable samples such as vaginal blood during hemorrhage to remove yet another barrier to access for actively bleeding women. The purpose of this study is to compare the hematocrit of vaginal blood using the Hemi device with standard venipuncture.

Detailed Description

This will be a prospective cohort study. The investigators will recruit 41 pregnant women admitted for delivery. Following delivery, a sample of vaginal blood will be collected and the Hemi device will be used to obtain hematocrit. These results will be masked to the clinical team until the time of data collection. A CBC will also be collected via venipuncture at this time. This study will be comparing hematocrit levels by standard clinical laboratory versus results from the device.
