Emergency Care: Bleeding and Shock

A collection of flashcards covering key terminology and concepts related to bleeding and shock as discussed in the emergency care lecture.

Hemorrhage

Severe bleeding that is a major cause of shock in trauma.

Capillary Bleeding

Slow and oozing bleeding caused by superficial wounds to the surface of the skin.

Arterial Bleeding

Bright red, spurting blood that is oxygen-rich, associated with rapid blood loss.

Venous Bleeding

Darker in color than arterial bleeding, it has lower pressure and can be life-threatening.

Shock

Inadequate tissue perfusion that can lead to cellular and organ death if not addressed.

Cardiogenic Shock

Shock caused by the heart's inability to pump blood effectively, often related to mechanical issues.

Hypovolemic Shock

Shock resulting from volume loss due to bleeding or fluid loss.

Distributive Shock

Shock caused by the dilation of blood vessels, preventing adequate filling of the circulatory system.

Obstructive Shock

Shock that occurs when blood flow is blocked by conditions such as a pulmonary embolism.

Compensated Shock

The body's attempt to maintain perfusion through compensatory mechanisms.

Decompensated Shock

A state in which the body can no longer compensate for low perfusion, leading to decreased blood pressure and altered mental status.

Perfusion

The adequate circulation of blood throughout the body to supply tissues and organs.

Pressure Dressing

Dressings applied to wounds to maintain pressure and control bleeding.

Tourniquet

A device used to compress blood vessels and stop bleeding, typically used for extremity injuries.

Hemostatic Agents

Substances used to enhance the body’s ability to clot and control bleeding.

Neurogenic Shock

Shock resulting from the loss of sympathetic tone, leading to vasodilation and a drop in blood pressure.

Junctional Hemorrhage

Massive bleeding that occurs where limbs attach to the trunk of the body.
