Flashcards in Hematologic Emergencies Deck (24):
1

Plasma

92% water 6-7% proteins
Accounts for 55% of blood

2

Erythrocytes

Red blood cells

3

Leukocytes

White blood cells

4

Thrombocytes

Platelets

5

Production of RBC's

Occurs within stem cells inside of the bone marrow

6

Hemoglobin

Identifies amount of hemoglobin found within the RBC's

7

Hematocrit

Proportion of red blood cells in the blood

8

WBC's

Larger than RBC's provide body with immunity against foreign invaders

9

Platelets

Are smallest of formed elements
Form initial clot following injury

10

Hemostasis

Process body takes to stop bleeding

11

Clotting Factors

Liver produces clotting factors and filters, removes toxins of RBC's
As old RBC's enter liver and are broken down they are formed into bile

12

Spleen

Filters and breaks down RBC's as well
Helps produce lymphocytes

13

ABO System

Types of blood A B AB O
A antigen is A
A antibody is B

14

Clotting Cascade

Process by which clotting factors work together to form fibrin

15

Coagulopathies

Bleeding Disorders that can lead to heavy or prolonged bleeding

16

Sickle Cell Disease

Leading inherited blood disorder
Sickle shaped RBC's make the cells poor carriers for oxygen
May cause cells to lodge in small vessels

17

Aplastic Crisis

Body Stops production of Red blood cells, causing the patient to become easily tired, nemic, pale and sob

18

Hemolytic Crisis

Acute red blood cell destruction leading to jaundice

19

Splenic Sequestration Crisis

Caused by sickle cells within spleen blocking blood from leaving the spleen, which results in painful, acute enlargement of spleen and a hard bloated abdomen
Oxygen and Pain Management

20

Anemia

Defined as hemoglobin or RBC's level lower than normal

21

Iron deficiency anemia

SOB, worn down, weak

22

Leukemia

Disease in lympnode system
Can cause frequent bleeding, bruising, infections and fever

23

Lymphomas

Group of malignant diseases that arise within lymphoid system

24

Hodgkin lymphoma

Painless, progressive enlargement of the lymphoid Glands, most commonly affecting spleen and lymph nodes
