Red blood cells (RBCs) AKA: Erythrocytes CONTAIN A PROTEIN MOLECULE CALLED______.
BREAK DOWN THIS PROTEIN.
WHAT DOES HEMOGLOBIN DO?
LIFE SPAN?
HEMOGLOBIN
HEME (IRON)
GLOBIN (PROTEIN)
IT CARRIES O2 AND IRON
120 DAYS
_________ (released by the kidney) production rises as a consequence of hemorrhage
_______ (process of RBC production)
Hematocrit = volume percentage of the total blood volume
ERYTHROPOIETIN
ERYTHROPOIESIS
WHAT ARE THE COMPONENTS OF A CBC? AND THEIR VALUE RANGES
RBC 4-6 PRIMARY JOB: CARRY O2 WHICH IS DONE VIA HEMOGLOBIN
HEMOGLOBIN 12-18 OXYGEN, IRON
HEMATOCRIT 34% TO 50% ALWAYS A PERCENTAGE
WBC 3,500 TO 10,500 OR 5,000 TO 10,000 IMMUNE
PLATELET 150-450 CLOTTING
WHERE ARE ALL, ALL BLOOD CELLS MANUFACTURED?
RED BONE MARROW
WHITE BLOOD CELLS (LEUKOCYTES) ARE
HIGHER WHEN….
ARE LOWER WHEN…
WHATS THE value RANGE OF THESE CELLS?
HIGHER WHEN FIGHTING INFECTION OR INFLAMMATION
LOWER WHEN IMMUNOCOMPROMISED
RANGE- 3,500 TO 10,500 OR 5,000 TO 10,000
THE DIFFERENTIAL OF A WBC CONTAINS SPECIFIC CELLS. WHAT ARE THEY AND THEIR PERCENTAGES.
NEVER LET MONKEYS EAT BANANAS
NEURTROPHIL 60% TO 70%
LEUKOCYTES 20% TO 40%
MONOCYTES 2% TO 6%
EOSINOPHILS 1% TO 4%
BASOPHILS 0.5% TO 1%
Hemostasis: A body process that arrests the flow of blood and prevents hemorrhage
WHAT CELLS DO THIS?
THROMBOCYTES- PLATELETS
COUNT 150,000 TO 450,000
THERE ARE 8 DIFFERENT BLOOD TYPES
WHAT ARE SUBSTANCES THAT CAN TRIGGER AN IMMUNE RESPONSE IF THEY ARE FOREIGN TOTHE BODY?
antigens – substances that can trigger an immune response if they are foreign to the body
1) Type AB IS CONSIDERED WHAT KIND OF RECIPIENT?
2) TYPE O IS CONSIDERED WHAT KIND OF DONOR?
1) UNIVERSAL RECIPIENT
2) UNIVERSAL DONOR- IT IS CONSIDERED THE SAFEST TO GIVE FOR BLOOD TRANSFUSION.
The ABO Blood Group System
GROUP A… antigen ____ on surface of RBC and __ antibody in plasma
Group B… antigen ___ on surface of RBC and __ antibody in plasma
Group AB..antigen ___ on surface of RBC and ___ antibody in plasma
Group O… antigen ___ on surface of RBC and ___ antibody in plasma
GROUP A… antigen A on surface and B antibody in plasma
Group B.. antigen B on surface of RBC and A antibody in plasma
Group AB… antigen AB on surface of RBC and NO antibody in plasma
Group O… NO ANTIGEN ON SURFACE OF RBC AND HAS A,B ANTIBODY IN PLASMA
The Rh antibodies destroy some of the fetal red blood cells. This causes ________ _____, where red blood cells are destroyed faster than the body can replace them.
HEMOLYTIC ANEMIA
INR is a standardized test, results will be the same and is figured out using the results of the prothrombin time (PT) test.
WHAT IS THE NORMAL INR RANGE?
International normalized ratio
INR 0.8 to 1.2
COAGULATION STUDIES
Used to monitor patients taking anticoagulant – PROLONGED IF > abnormal values
Anticoagulation therapy is prescribed for patients after myocardial infarction to dissolve thrombus.
• Also used for chronic atrial fibrillation or cardioversion – restoring heart normal rhythm by delivering shock through two metal paddles placed on patient’s chest.
Prothrombin time PT _____ TO _____seconds
Prothrombin time PT 11-14 seconds
COAGULATION STUDIES
NORMAL RANGE FOR PTT: ___ TO ___ SECONDS
Partial thromboplastin time
PTT 25-35 seconds
Disorders Associated with Erythrocytes: Name the description of the disorder below:
• Disorder characterized by RBC and hemoglobin and hematocrit levels below normal range
• Causes delivery of insufficient amounts of oxygen to tissues and cells
Anemia
Average adult has approximately 6 liters (12 pints) of total blood volume
WHAT CONDITION CAN RESULT IF NOT ENOUGH BLOOD VOLUME?
HYPOVOLEMIC ANEMIA OR BLOOD LOSS ANEMIA
Oliguria – (small amount of urine- less than 400 ml in 24 hours) AND IS ASSOCIATED IN THE SLIDES WITH WHAT DISORDER?
HYPOVOLEMIC ANEMIA/SHOCK
THREE STAGES OF SHOCK:
WHAT STAGE OF SHOCK IS (also called compensated, or nonprogressive), when low blood flow (perfusion) is first detected.
S/S: confused with cool and clammy skin, decreased urinary output
STAGE 1
THREE STAGES OF SHOCK
WHICH STAGE of shock is irreversible, the length of time that poor perfusion has existed begins to take a permanent toll on the body’s organs and tissues.
Patient becomes unconscious. The endpoint of This stage is patient death.
STAGE 3
Where is the intrinsic factor located and what causes it to be absent?
A LACK OF INTRINSIC FACTOR CAUSES PERNICIOUS ANEMIA.
HAPPENS OFTEN AFTER GASTRIC SURGERY!
Intrinsic factor is a protein that helps your intestines absorb vitamin B12. It is made by cells in the stomach lining. Intrinsic factor binds to vitamin B12. VITAMIN B12 IS NEEDED FOR RBC TO FORM AND GROW.
PERNICIOUS ANEMIA IS CAUSED BY NOT GETTING ENOUGH VIT B12
What is the medical management of sickle cell anemia?
Increase fluids (at least 8 glasses of fluid daily)
More fluid means lower viscosity/thickness
Analgesics
Pain control is necessary during crisis – morphine and
hydromorphone (Dilaudid)
What is a Blood disorder characterized by hyperplasia (overgrowth) of the bone marrow with Manifestations of Overproduction of circulating erythrocytes (erythrocytosis), granulocytes, and platelets?
It is characterized by an ^ of RBC in bloodstream, ^ hemoglobin and hyper viscosity, excess wbc and platelets.
Polycythemia (erythrocytosis)
There is an ^ of bleeding disorders
MM and NI for Polycythemia (erythrocytosis)
+Reduction of blood viscosity
+Repeated Phlebotomy – removal of 500 to 2000 ml of blood until Hct level is maintained at 45-48%
What are the normal values for HCT and HGB?
HCT 35-45%
HGB 12-18
