Record the total volume of fluid collected in the under-buttocks drape. Subtract the preplacental fluid volume from the post placenta fluid volume to more accurately determine the actual blood loss. Keep in mind that most of the fluid collected after the birth of the placenta is blood.

Definition and Prevalence. Postpartum hemorrhage (PPH) is commonly defined as blood loss exceeding 500 mL following vaginal birth and 1000 mL following cesarean.

How is blood loss measured after delivery?
When the bleeding stops, there are two options: the bag can be weighed (also called gravimetric technique), or the bag can be calibrated, allowing for a direct measurement. A more precise measurement of blood loss is haemoglobin concentration (Hb) in venous blood sampling and spectrophotometry.

What causes excessive bleeding after delivery?
Postpartum hemorrhage is mainly caused by uterine atony. Normally, the uterus squeezes or shrinks after delivery to stop bleeding where the placenta was attached. With uterine atony, the uterus doesn’t contract the way it has to do and ultimately that causes frequent heavy bleeding after giving birth.
What is the usual blood loss from a normal vaginal delivery?
The average amount of blood loss after the birth of a single baby in vaginal delivery is about 500 ml (or about a half of a quart). The average amount of blood loss for a cesarean birth is approximately 1,000 ml (or one quart). Most postpartum hemorrhage occurs right after delivery, but it can occur later as well.
