MilitaryMoulage.com Curriculum Development Specialist & Instructor Suzanne Patterson shared Part 2 of her article on Theatrical Blood Effects for Realistic Casualty Simulation! MilitaryMoulage.com (or MMCIS™) provides “the highest quality moulage training workshops for military and civilian casualty simulation personnel, regardless of their skill level, which helps companies or individuals achieve the greatest value for training investment dollars.”
Excerpt from the article:
“High fidelity blood simulation is a pivotal component in creating true-to-life bleeding traumas for accurate response in training, so there are some physiology facts to keep in mind about it when you are planning blood loss in your scenarios. First of all, the human body contains roughly a gallon plus a quart of blood, about 168 ounces, and depending on the body size. Clinical symptoms of hypovolemia (shock due to blood loss) becomes apparent after about 20% or 1/5th of whole-blood volume has been compromised, so be aware of this detail when assigning large blood loss type of injuries.
Blood color is also an important factor because there are two distinct types of blood that circulate throughout the body. Artery blood is oxygenated as it moves away from the heart and lungs, so it is a lighter or brighter red looking blood. Venous blood is a darker red hue because it is oxygen depleted and high in carbon dioxide as it travels back to the heart. You’ll need to determine how much theatrical blood of both colors will be needed to portray active bleeding through the flowing, dripping, or oozing from compromised veins and arteries portrayed, as well as any splashing, splattering, or smearing resulting from contact or an impact.”
