Emergency Care and Transportation of the Sick and Injured - Chapter 26

These flashcards are designed to help students review key vocabulary and concepts related to the management of bleeding and emergency medical care.

Hemorrhage

Bleeding; can be external (visible) or internal (not easily detected).

Perfusion

The circulation of blood within an organ or tissue to meet cells’ needs for oxygen, nutrients, and waste removal.

Hypovolemic Shock

A condition that occurs when more than 20% of blood volume is lost, leading to inadequate perfusion.

DCAP-BTLS

A mnemonic used to assess for signs of injury: Deformities, Contusions, Abrasions, Punctures, Burns, Tenderness, Lacerations, and Swelling.

Tourniquet

A device used to apply pressure to a limb to stop bleeding, particularly in cases of severe hemorrhage.

Atrioventricular Valve

A heart valve that allows blood to flow from the atria to the ventricles, preventing backflow.

External Bleeding

Visible bleeding from an injury which may require immediate intervention to control.

Capillary Bleeding

Bleeding from damaged capillaries, appearing dark red and oozing steadily.

Arterial Bleeding

Bright red bleeding that spurts with each heartbeat, often difficult to control.

Venous Bleeding

Dark red blood that flows steadily, typically easier to control than arterial bleeding.

Clotting

The process of blood coagulation that helps to stop bleeding when a blood vessel is injured.

Signs of Internal Bleeding

Including pain, swelling, and symptoms of hypoperfusion such as hypotension and tachycardia.

Elderly Considerations

Older patients are more prone to complications from hypertension and may experience bleeding issues.

History Taking

A process to investigate a patient's medical history, particularly related to injuries and medications affecting bleeding.

BCI (Blood Clotting Indicator)

A factor indicating the risk of serious bleeding, especially in hemophiliac patients.

IV Fluids

Intravenous fluids used to assist in maintaining perfusion and blood volume during treatment.

Pressure Dressing

A bandage applied firmly around a wound to control bleeding.
