Shock
Cards (11)
- Pump failure
- cardiogenic shock
- obstructive shock
- tension pneumothorax
- cardiac tamponade
- pulmonary embolism
- poor vessel function
- distributive shock - septic, neurogenic, anaphylactic, psychogenic
- low fluid volume
- hypovolemic shock - hemorrhagic and nonhemorrhagic shock
- causes of cardiogenic shock include disease or illness affecting the heart
- Neurogenic shock any factor that stimulates parasympathetic activity or inhibits sympathetic activity of vascular smooth muscles can cause neurogenic shock, which results in widespread and massive vasodilation
- Neurogenic shock any factor that stimulates parasympathetic activity or inhibits sympathetic activity of vascular smooth muscles can cause neurogenic shock, which results in widespread and massive vasodilation
- causes of neurogenic shock include CNS trauma and vasomotor center depression (e.g. severe pain, drugs, hypoglycemia), inhibitors of sympathetic nervous activity
- signs of compensated shock include agitation, restlessness, anxiety; AMS (altered mental status); tachycardia; tachypnea (fast breathing); changes in skin CTC; nausea, vomiting; weak peripheral pulse (with strong, fast central pulse)
- signs of decompensated shock include falling BP (systolic <90 in adults, <70 in kids); tachycardia and tachypnea; low urine output; labored and irregular breathing; weak, thready, or absent peripheral pulses; cool, clammy skin; cyanosis; dilated pupils
- treating cardiogenic shock: Put patient in position of comfort, Treat for cardiac compromise - oxygen, aspirin, assist with nitro, Rapid transport, ALS
- neurogenic shock - spinal cord restri ction
