At what rate can intercostal muscles bleed?

The intercostal muscles, which are located between the ribs and assist with breathing by expanding and contracting the rib cage, can indeed be a source of significant hemorrhaging when injured. The correct answer, indicating a bleeding rate of 100 mL per minute, reflects the high vascularity of these muscles.

In cases of trauma or injury to the thoracic region, the intercostal arteries can be severed or damaged, leading to rapid blood loss. Understanding this rate is crucial for combat medics as it underscores the potential for life-threatening situations if major vessels are compromised. Recognizing the symptoms of significant bleeding from these muscles, such as difficulty breathing, significant chest pain, or visible trauma, is critical for effective assessment and intervention.

This bleeding rate is a practical benchmark that helps medics assess the severity of a patient's condition and prioritize treatment accordingly, particularly in emergency situations where quick decisions can be the difference between life and death.
