Oxygenation Flashcards
(29 cards)
This is the most potent stimulant during oxygenation.
Carbon dioxide
This means that there is an insufficient supply of oxygen required by the body.
Hypoxia
This type of hypoxia is for when there is a deficiency in the oxygen exchange in the lungs.
Hypoxic hypoxia
This type of hypoxia is for when the body cannot transport oxygen even though it’s available.
Anemic hypoxia
This type of hypoxia is for when there is insufficient blood flow.
Stagnant hypoxia
This type of hypoxia is considered fake because one’s oxygenation levels maybe normal or even higher.
Histotoxic hypoxia
Complete the formula:
V02 = ____ x _____ x ____ x (_____ - _____)
The attached formula is for oxygen delivery
V02 = 1.39 x Q x Hb x (SaO2 - SvO2)
where Q = blood flow (ml/min)
Hb = hemoglobin (gm/dl)
SaO2 = % saturation of arterial blood (100 mmHg)
SvO2 = % saturation of venous blood (40 mmHg)
What are the three main functions of the blood?
- Transportation
- Regulation
- Protection
This is the physiologic act of bleeding control.
Hemostasis
Scabs are made up of which material?
Fibrin
Erythrocytes easily pass through the blood vessels because of its _____________.
Biconcave shape
YES OR NO - the ff. steps of hemostasis is arranged in the proper order
Coagulation phase - activation of clotting system and clot formation
Platelet phase - platelet aggregation and adhesion
Vascular phase
Clot destruction - ezymatic destruction of clot
Clot retraction - contraction of blood clot
NO - the steps are not in order
Vascular phase
Platelet phase - platelet aggregation and adhesion
Coagulation phase - activation of clotting system and clot formation
Clot retraction - contraction of blood clot
Clot destruction - ezymatic destruction of clot
The liver functions as a _________ and __________.
Reserve RBC supply; iron storage, plasma protein and clotting factor synthesizer
The spleen functions as a _________ and _________.
Reserve RBC supply; removes old RBCs from circulation
The bone marrow is _________________.
Where RBCs and plasma are formed.
It is the process of RBC production.
Erythropoeisis
The hormone ____________ is produced in the _________ which stimulates the bone marrow to produce more RBCs.
Erythropoietin; kidneys
It is a type of anemia caused by an increase in the RBCs rate of destruction.
Hemolytic anemia
This anemia is may be caused by defective heme synthesis and symptoms include pallor along with glossitis and cheilitis.
Iron-deficiency anemia
This causes megaloblastic anemia because the GI tract is not producing enough intrinsic factor - a necessary substance in the absorption of this mineral. This condition is coupled with altered thought processes like confusion and dementia.
Cobalamin (Vitamin B12 Deficiency)
This is the main cause of _________ anemia in which RBCs are large and few. The main difference of this from the previous type of anemia is that there is an absence of neurologic conditions.
Folic Acid Deficiency; magablastic anemia
This is an autosomal recessive condition in which there is an irregularity in the production of either the alpha or beta globin chains - leading to a decrease in hemoglobin production.
Thalassemia
_____________ is a type of anemia caused by bone marrow failure. It’s called ______________ if it’s inherited.
Aplastic anemia; fanconia anemia
Pancytopenia is when there is a decrease in _________________.
All blood cell types
