104 - Expeditionary First Aid

Question 1

Types of Bleeding

Answer 1

• Arterial: Arterial blood is bright red because it is rich with oxygen traveling through arteries. The arteries deliver the oxygen rich blood to all the vital organs in the body
• Venous: Venous blood is dark red because it is low in oxygen. Venous blood is the blood traveling through the veins of the body, back to the lungs and releases CO2 to pick up more oxygen.
• Capillary: Slow even flow

Question 3

Tactical Combat Casualty Care Triage Categories

Answer 3

• Minimal: These casualties have relatively minor injuries and can effectively care for themselves or can be helped by non-medical personnel.
• Expectant: These casualties have wounds that are so extensive that even if they were the sole casualty and had the benefit of optimal medical resource application their survival would be unlikely. Using minimal but competent staff, provide comfort measures for these casualties.
