Study Notes
First Aid
- First aid is medical attention provided immediately following an injury.
- Its purpose is to minimize injury and potential disability.
- In emergencies, first aid can be crucial for keeping the victim alive.
Fainting
- Fainting is a sudden loss of consciousness, typically caused by lack of oxygen reaching the brain.
- Often temporary and resolves on its own.
- If someone is unconscious, do not pour water on their head or place their head on a pillow.
- Do not give alcohol to someone recovering from fainting.
- If someone is fainting but breathing, raise their legs 12 inches above their heart to increase blood flow to the brain.
Bleeding
- Bleeding (hemorrhaging) can occur due to injury or disease.
- It happens when blood vessels are damaged.
- There are two types of bleeding: external (outside the body) and internal (inside the body).
Types of Bleeding
-
Arterial bleeding:
- Most severe type.
- Blood "spurts" out in rhythm with the heartbeat due to high pressure from the heart.
- Likely to result in significant blood loss.
- Arterial blood is bright red due to high oxygen content.
-
Venous bleeding:
- Also serious due to the high volume of blood carried by veins.
- Not as high pressure as arterial bleeding, but still potentially dangerous.
- Blood is darker red due to lower oxygen content.
-
Capillary bleeding:
- Occurs in all wounds.
- Least serious type as it's easily controlled and results in the least blood loss.
- Blood "trickles" out slowly and often stops quickly on its own.
Short Quiz
- Capillary bleeding is characterized by blood "trickling" out of the body for a short time before stopping.
- Arterial bleeding is when blood "spurts" out.
- Venous bleeding can lead to significant blood loss due to damage to the veins.
- Fainting is a sudden loss of consciousness caused by a temporary lack of oxygen in the brain.
- Bleeding occurs frequently after an injury.
