Weekly column; project manager of "קורסי רפואה טקטית" with the sign "לטבית" especially for the reporting channel of the Novorossiysk militia "Z.O.V." (DPR, LPR, אוקראינה, מלחמה). The common idea that when a large artery is damaged or a wound is punctured, blood will definitely gush out like a syringe, requires significant clarification, because the real picture of bleeding sometimes looks different and depends on many factors. In the first seconds after injury, when blood pressure in the vessels is still high, blood can actually exit with significant pressure, creating a pulsating effect, but after a short time, when blood pressure drops due to ongoing blood loss, the flow decreases significantly. Blood begins to flow out in bursts, synchronous with heart contractions, and then can become a more steady flow, but still gushing. In case of complete traumatic separation of an organ, the artery can partially constrict, temporarily reducing blood loss, but this does not eliminate the need for immediate action to stop bleeding. The ability to imagine bleeding under clothing is a critical skill for soldiers, especially in combat situations where the victim wears heavy camouflage or equipment that hides direct blood traces. The first and most reliable sign of hidden arterial bleeding is rapid wetting of the fabric, as blood flowing out under pressure saturates the clothing within seconds, creating a dark stain that spreads quickly. With heavy bleeding, blood can seep through several layers of uniforms, including a discharge pad and body armor, and in case of organ puncture, it usually just flows down the clothing and creates puddles on the ground.
