T4 Hemodynamic disor

PATHO exam 1 review

Edema occurs when there is an imbalance in ______ and _____ pressure Hydrostatic, Oncotic
Edema is an _____ of fluid in the bodys tissues accumulation
Pathogenesis of edema :_____ Hydrostatic pressure causes a _______ in oncotic pressure = edema Increased, Decreased
Pathogenesis of edema: _______ hydrostatic pressure causes a ______ in permeability of the venule = Edema Increased, Increase
Normally _#_ml/min blood leaves the atrial BV and _#_ ml/min enters the Lymphatic organ to get filterd while the other _#_ ml/min returns to the venule 14,2,12
In edema when increasing ______ pressure the fluid does not return to the venule and begins to build up in body tissue . which also causes and increased rate of _______ for both venule and atrial side causing more fluid to enter the tissues Hydrostatic, permeability
In edema when there is a Decrease in _______ pressure this results in failure of the fluid to return to the venule and remain in the body tissue Oncotic
____ ______ occurs when a tumor or object(worm in Africa) is blocking the entrance of fluid into the lymphatic organ Lymphatic obstruction
Hyperemia is an increase in ? Temperature
2 types of Hyperemia Active and Passive
Type of Hyperemia that consists of dilatation of arterioles – Blushing, exercise, inflammation (more normal homeostasis process) Active Hyperemia
Type of Hyperemia that consists of decrease of venous flow; often associated with hydrostatic edema. Passive hyperemia (congestion)
Chronic Passive hyperemia of liver :The liver in patients with ____ ventricular failure results in a characteristic of ‘Nutmeg liver’ (multiple red depressed cells). right
Chronic Passive hyperemia of lung: The lung in the patients with___ ventricular failure often leads to alveolar fibrosis (brown induration of the lung). The _____ in the lung are known as ‘Heart failure cells’. (may be caused by smoking) left, macrophages
what parts of the circulatory system have the highest blood volume ? and what has the least blood volume Veins and venules (64%) have the most , Arteries & arterioles (13%), Capillaries (7%) have the least
What type of Hemorrhage has a BRIGHT red color and has a pulsating flow (squirts RAPIDLY) Atrial Hemorrhage
What type of Hemorrhage has a DARKER red color and has a steady SLOW flow ? Venous Hemorrhage
What type of Hemorrhage has a reddish mixed with blue , violet color and has a slow, even flow ? Capillary Hemorrhage
_____ Hemorrhage results from soft tissue injury (You can see it ) , External
For External Hemorrhage The seriousness of the injury is dependent on : 2 Things 1.Anatomical source of hemorrhage (aterial,venous,capillary) 2. The amount of blood loss tolerated by the patient
Humans have apron. how many liters of blood ? and whats the max u can lose ? 6.5L, no more then 3 liters can be lost
External hemorrhage : Most soft tissue trauma is accompanied by ___ hemorrhage and is not life threatening , but can carry serious risks of patient morbidity and disfigurement mild
_____ Hemorrhage that can be deadly because you CANT see it Internal
Internal Hemorage : can result from Blunt or penetrating trauma , Acute or Chronic medical illness
Internal bleeding that can cause hemodynamic instability usually occurs in one of four body cavities: Chest, Abdomen, Pelvis, Peritoneum(stomach)
How is internal hemorrhage found ? Though a diagnostic test
6 Clinically important forms of Hemorrhage ? Skin hemorrhage, Hemopytsis, Hematemesis, Hematuria, Metrorrhagia, Melena
________ : skin bleeding Skin hemorrhage
________ : Respiratory Tract bleeding Hemoptysis
________: Vomiting blood Hematemesis
________: Blood in urine Hematuria
________: Utero-vaginal bleeding (abnormal menstrual bleeding) Metrorrhagia
________: Black (deoxygenated) blood in stool or feces NOT hemorrhoids Melena
______ is a Big clot formation inside the blood vessels (BAD when in blood vessels) Thrombi (blood clot)
Lines of Zhan consists of ____ and ____ which are responsible for the shape of______ Fibrin, Platelets, Thrombus
Virchow's triad shows what 3 factors that contribute to Thrombosis ? The factors may act independently or may combine to cause thrombus formation. Endothelial Injury, Abnormal blood flow, Hypercoagulability
What drug stops bleeding in dental surgery ? Thrombrin
What does Thrombi(blood clot) consist of ? Fibrin mesh network, RBC, WBC, Platelets
_____ injury is the single most important factor in formation of thrombi Endothelial
Injury to endothelial cells can cause ____ ____ flow and affect_____ abnormal blood, coagulability
Abnormal blood flow (stasis or turbulence), in turn, can cause ____ injury. endothelial
Drug/protein given for heart and stroke patients (thrombosis) (TPA) Tissue Plasminogen Activator
(TPA) Tissue Plasminogen Activator is a ____/____ that is released from _____ cells of ____ _____ which cleaves the _____ and _____ the clot drug/protein, endothelial, Blood vessels, dissolves
According to the AHA (american heart association) for CARDIAC patients TPA has to be given with in ____ hours of the event. (heart attack) 6 hours
According to the AHA (american heart association) for STROKE patients TPA has to be given with in ____ hours of the event. (stroke) 3 hours
Carotid & cerebral arteries, Aorta, Heart valve, varicose veins & coronary arteries are all common sites of ? Thrombus formation
Can thrombi be in the arteries and in the veins ? Yes, Atrial and venous thrombi
What are the possible Fates of thrombi ? Lysis by TPA, organization (not often), Recanalization, Embolism
Free moving mass (clot) carried from one anatomic site to another via..blood Emobli or Embolis , (chunk of thrombi that broke off and traveled somewhere else
The worst type of clot formation, called widow maker, can die in sleep, acts very quickly , consists of calcified clots. Saddle Embolus
SADDLE EMBOLUS Location: Pathogenesis: Location: Pulmonary Artery Pathogenesis: cuts down blood supply to the heart
Infraction is Necrosis ( death of tissue)
2 types of infracts White & Red
Type of infract that has a (pale) off red appearance usually found in the heart ? White infract
Typeof infract that has a hemmorrhagic appearance "dark red" usually found in intestine ? Red Infract
The fate of infarcts depends on their____ site, the type of cells forming the tissue, circulatory status of the organism, extent of necrosis, anatomic
