Antecubital Fossa
|
The portion of the arm that is in front of the bend of the elbow. The most prominent veins for venipuncture are located in this area.
|
|
Anticoagulant
|
Chemical substance that prevents the blood from clotting.
|
|
Basilic Vein
|
The vein on the little finger side of the arm running the length of the arm.
|
|
Buffy Coat
|
Layer of cells in an anticoagulant tube of blood that is positioned between the RBC's and plasma layers. Consists of WBC's and platelets.
|
|
Centrifuge
|
Instrument that spins and separates blood into layers depending on the weight of the layer. The heavier elements are pushed to the bottom due to centrifugal force.
|
|
Cephalic Vein
|
The vein on the thumb side of the arm running the length of the arm. Second choice for venipuncture.
|
|
Diastolic
|
Blood pressure when the heart is at rest. Blood refills the ventricles.
|
|
Endocarditis
|
Infection of the inner membrane of the heart.
|
|
Erythrocytes
|
Formed blood element; also known as red blood cells.
-transports 02 and CO2 with hemoglobin -formed in bone marrow -size 6-7 micrometers (no nucleus) -life span 100-120 days -removed in bone marrow, liver, and spleen |
|
Leukocytes
|
Formed blood element; also known as white blood cells.
-body defense -formed in bone marrow and lymphatic tissue -size 9-16 micrometers; eosinophils, neutrophils, and basophils (granular) monocytes and lymphocytes (agranular) -life span 24 hours-years -removed in bone marrow, liver, and spleen |
|
Median Cubital Vein
|
The vein in the antecubital Fossa area of the arm that bridges the cephalic and basilic veins. Easiest to palpate and used the majority of the time in venipuncture.
|
|
Occluded
|
Blocked, preventing a normal flow of blood.
|
|
Plasma
|
Fluid portion of the blood when no clotting has taken place. Contains fibrinogen.
|
|
Pulmonary System
|
System circulating blood through the lungs.
|
|
Serum
|
Fluid portion of the blood after clotting has taken place.
|
|
Systemic System
|
System circulating blood throughout the body with the exception of the lungs.
|
|
Systolic
|
Blood pressure when the heart is fully contracted.
|
|
Thrombocytes
|
Formed blood element; also known as platelets.
-stops bleeding -formed in bone marrow from megakaryocytes -size 1-4 micrometers -life span 9-12 days -removed in spleen |
|
Blood Draw Calculations
|
-150lb adult = 5L total blood
-2.2lb infant= .100L total blood -2.5% blood max per draw -5% blood max per 30 days -blood contains 45% formed elements and 55% plasma |
|
Arteries vs. Veins
|
Arteries
-carry oxygenated blood from the heart -Bright red color -Elastic walls expand with blood surge -No valves -smooth muscle in tunica media for dilation and constriction -can feel a pulse Veins -carry deoxygenated blood to the heart -dark red color -less elastic walls -valves -no pulse |
|
Complete Blood Count (CBC) Components
|
WBC's (differential), RBC's, Platelets, Hemoglobin, and Hematocrit
|
