How do you quantify bleeding?

Weigh all blood-soaked materials and clots to determine cumulative volume. 1 gram weight=1 milliliter blood loss volume. The equation* used when calculating blood loss of a blood-soaked item is WET Item Gram Weight - DRY Item Gram Weight=Milliliters of Blood Within the Item.

What is considered to be the best method of estimating blood loss following birth?

The most frequently used method is a visual estimation of blood loss (VEBL), during which the birth attendant makes a quantitative or semi‐quantitative estimate of the amount of blood lost.

What techniques can be used to make a more accurate estimation of blood loss?

There are many methods for intraoperative blood loss estimation, e.g., gravimetric, photometry, and visual estimation, but the most used method is visual estimation.

What does quantitative blood loss mean?

Implementation of quantitative assessment of blood loss includes the following two items: 1) use of direct measurement of blood loss (quantitative blood loss) and 2) protocols for collecting and reporting a cumulative record of blood loss postdelivery.
