Term
Occurs when there is circulatory insufficiency between tissue oxygen supply and the resting metabolic demands of the tissues.
Definition
Shock
Term
Hypovolemic, cardiogenic, distributive, obstructive
Definition
4 classes of shock
Term
A patient in shock may have an elevated or subnormal temperature.  T/F
Definition
True
Term
Shock is associated with a systolic BP below _____?
Definition
90mm Hg
Term
Persistent elevations greater than 1.0 of the shock index indicates ???
Definition
impaired left ventricular function and is associted with increased mortality.
Term
Neck vein distention, flattening and cardiac dysrhythimias.
Definition
Cardiovascular manifestations of shock
Term
Complete blood count, electrolytes, platelet count, blood urea nitrogen, creatinine determinations, prothrombin and partial prothrombin times, urinalysis.
Definition
Frequently preformed lab studies for shock
Term
Aggressive airway control is best obtained through ???
Definition
Endotracheal intubation
Term
Isotonic crystalloid intravenous fluids in the intial resusitation phase.
Definition
ER intervention of shock
Term
______ is the ideal resuscitation fluid for shock.
Definition
Blood
Term
Used after appropriate volume resucitation has occurred and there is persistent hypotension.
Definition
Vasopressors
Term
Used when systolic BP is over 100 mm Hg.
Definition
dobutamine 2.0 to 20.0 micrograms/kg/min
Term
Used when systolic BP is 70-100 mm Hg
Definition
dopamine 5.0 to 20.0 micrograms/kg/min
Term
Used for systolic BP of above 70 mm Hg.
Definition
epinephrine 0.5 to 30.0 micrograms/kg/min
Term
_____ should be treated with adequate ventilation and fluid resusitation.
Definition
Acidosis
Term
Can be caused by any class of microorganism.
Definition
Septic Shock
Term
The majority of septis occurs with which bacteria?
Definition
Gram negative and gram positive bacteria
Term
Predisposing factors such as DM, lymphoproliferative diseases, cirrhosis, burns, invasive procedures and chemotherapy occur with which bacteria?
Definition
gram negative bacteria
Term
Risk factors such as vascular catheters, burns, indwelling mechanical devices, and injection drug use are risk factors for which bacteria?
Definition
Gram positive bacteria
Term
Retinal hemmorages, cotton wool spots, and conjunctivial petechiae are manifestations of ???
Definition
Ophthalmic for septic shock
Term
Hyperprexia, mental status changes, tachycardia, wide pulse pressure, tachypnea, warm extremities, hypoxemia, renal failure with azotemia and oliguria, liver dysfunction.
Definition
Clinical features of septic shock.
Term
T/F-- Hemoglobin and hematocrit are usually not affected unless the sepsis is prolonged or there is an associated GI bleed.
Definition
True
Term
May result from increased catecholamines, cortisol, and glucagon.
Definition
Hyperglycemia
Term
Blood gases show hypoxemia and a respiratory acidosis. As perfusion worsens, and glycolysis increases, a metabolic acidosis occurs from decreased tissue perfusion, glycolysis in perpherial tissues and impaired hepatic clearance of lactate and pyruvate.
Definition
Early sepsis
Term
Should be suspected in any patient with a temp above 38 degrees C. or below 36 degrees C, systolic BP below 90 mm Hg and evidence of inadequate organ perfusion.
Definition
Septic shock
Term
Ceftriaxone IV, Cefotaxime IV, or Ceftazidime IV
Definition
Adult antibiotic therapy for sepsis
Term
High flow oxygen, keeping oxygen saturation greater than 90% through endotracheal intubation.
Definition
Aggresive airway management
