Shock States Flashcards
Shock States
Shock is a clinical syndrome of systemic hypertension, acidemia, and impairment of vital organ function resulting from tissue hypo perfusion
Hypovolemic Lab/Diagnostics
CO/CI: low CVP: low PCWP: low **SVR: high SV 02: low
Cardiogenic Lab/Diagnostics
CO/CI: low **CVP: High **PCWP: high SVR: high SV 02: low
Distributive shock
Three forms of shot characterized by vasodilation, decrease intravascular volume, reduced peripheral vascular resistance, and loss of capillary integrity. Distributive shock maybe
Septic
Anaphylactic
Neurogenic
Septic Lab/Diagnostics
CO/CI: high than low CVP: low than high PCWP: low than high SPR: low SP 02: low than high
Anaphylactic Lab/Diagnostics
CO/CI: low CVP: low PCWP: low SVR: low SVO2: low
Neurogenic Lab/Diagnostic
CO/CI: low CVP: low PCWP: low SVR: low SVO2: low
Obstructive Lab/Diagnostics
CO/CI: low CVP: high PCWP: normal/low SVR: high SVO2: high
Hypovolemic Shock
Results from a loss of greater than 20% of circulating blood volume
Hypovolemic shock causes
Internal/external bleeding
Burns
DKA
Severe dehydration
Hypovolemic shock management
Fluid resuscitation is the mainstay of treatment
Vasopressor supports
Packed red blood cells when indicated by hemoglobin/hematocrit
Cardiogenic Shock
A loss of effective contract tile function results in impaired cardiac output, impaired oxygen delivery, and reduced tissue perfusion
Cardiogenic shock causes
Acute am I: most common causes Ventricular aneurysm Dysrhythmia Pericardial tamponade Hypoxemia Pulmonary edema Acute valvular regurgitation Acute ventricular septal defect
Cardiogenic Shock Management
Initial, careful administration of IV fluids
Vasopressor support
Septic Shock
Caused by infective organisms which invade the bloodstream and alter vascular tone; hypovolemia develops as a result of blood pooling in the micro circulation
