SOPN SHOCK

QuestionAnswer
a syndrome resulting from sustained, inadequate tissue perfusion at the cellular and organ level Shock
What are the 3 stages of shock compensatory, progressive, and refractory
what is triggered by a decrease in cardiac output and a decrease in tissue perfusion = increase in lactic acid production Stage one - compensatory
an increase in the force of contraction of the heart = increase in cardiac output
an increased shunting of the blood to the vital organs = signs of cyanosis or pallor, pale, and cool moist skin
decreased kidney perfusion = decreased urinary output
decreased blood perfusion to the liver = stimulates production of glucose for increased energy production
What happens when the compensatory mechanism begins to fail to maintain BP and adequately perfuse VITAL organs, therefore, vital organs begin to fail due to lack of perfusion stage 2 or PROGRESSIVE STAGE
irreversible stage, body does not respond to interventions, multi organ failure with continured decrease in BP *death is imminent* 3rd stage - REFRACTORY STAGE OF SHOCK
name the types of shock Hypovolemic, cardiogenic, septic, neurogenic, and anaphylactic
what is caused by a lack o fblood, plasma, or interstitial fluid Hypovolemic shock
give examples of hypovolemic shock hemorrhage, diarrhea, burns, draining wounds, dehydration
How would you manage hypovolemic shock control source of blood loss and attempt to reverse the loss via transfusion, lactated ringers solution, shock position ect....
the hearts ability to pump is extremely impaired .....severe pump failure....therefore decrease in cardia output cardiogenic shock
what could cause cardiogenic shock myocardial infarction "MI" causing CHF this is the #1 cause!!!
balloon inserted via femoral artery for temporary circulatory assistance inflates during diastole and deflates during systole Intra-aortic balloon pump
characterized by hypotension and redistribution of blood flow- some areas are underperfused and some are overperfused Septic Shock
What causes sepsis toxins from micro-organisms that are released into the bloodstream
Massive vasodilation and redistribution of blood septic shock
massive vasodilation except to the vital organs causing a decrease in BP, skin warm and flushed, with increased heart rate, temperature, WBC count, and decreased LOC Hyperdynamic Shock
decreased cardiac output due to myocardial suppression, profound hypotension, ventricular failure, tachycardia, weak and thready pulse, SKIN PALE, COOL, & CLAMMY, decreased temp, patient unresponsive, increasesd BUN & Cr Hypodynamic Shock
1st line of defense with Septic Shock IV antibiotics
massive vasodilation resulting from loss or decrease in sympathetic nervous system can be associated with injury or disease of the spinal cord and/or brain stem also from general or spinal anesthesia neurogenic shock
Vasopressors used in the management of neurogenic shock Dopamine or dobutamine
what is used for bradycardia when dealing with neurogenic shock atropine
a sudden life threatening, hypersensitivity reaction to an antigen characterized by vasodilation and increased capillary permeability unless Rx'd immediatly could DIE!!! anaphylactic shock
what causes the following reactions: bronchial constriction, vasodilation: decreased BP, increased capillary permeability HISTAMINES
What are the main signs and symptoms of anaphylactic shock INCREASED HEART RATE AND INCREASED PULSE *feelings of anxiety, uneasiness*
#1 method to manage anaphylactic shock: a vasoconstrictor that improves blood flow to the heart and brain epinephrine
what helps reverse vasodilation and reverses bronchospasm epinephrine
what is given during anaphylactic shock to increase BP Dopamine
what is the most frequent cause of cardiac arrest MYOCARDIAL INFARCTION "MI" from coronary artery disease
what causes the cardiac ischemia from occulded coronary arteries artherosclerosis
purpose is antifibrillatory - used to treat ventricular fibrillation that does not respond to epinephrine Lidocaine
purpose - used to treat symptomatic bradycardia - LOW HEART RATE Atropine
purpose - used to treat shock and correct hemodynamic imbalances - improves perfusion to vital organs, increases CO and corrects hypotension DOPAMINE
purpose - used for life threatening ventricular arrythmias, works by prolonging refractory period, inhibits adrenergic stimulation, slows rate, increases "PR" interval AMIODARONE
