,Low blood flow cardiogenic shock -comprimised cardiac output. systolic and diastolic
dysfunction
CAUSES
-MI, cardiomyopathy, blunt cardiac injury, severe
systemic or pulmonary HTN, cardiac tamponade,
myocardial depression from metabolic problems
EARLY MANIFESTATIONS
-tachycardia
-hypotension
-narrowed pulse pressure
-increased myocardial o2 consumption
-tachypnea, pulmonary congestion, decreased cap
refill time
-anxiety, confusion, agitation, increased pulmonary
artery wedge pressure, decreased UO
INTERPROFESSIONAL CARE
-goal: decrease heart workload
-angioplasty w stenting, vavle replacement
-hemodynamic monitoring
-drugs: nitrates, diuretics, vasodilators, b adrenergic
blockers
,Low blood flow hypovolemic shock -absolute hypovolemia: loss of intravascular fluid
volume
-when fluid moves out of the vascular space into the
extravascular space
-*burns?
TYPES?
-hemorrhage, vomiting, diarrhea
-fistula drainage, diabetes insipidus
-hyperglycemia, diuresis
MANIFESTATIONS
-anxiety, tachypnea, increased CO, heart rate
-decrease in stroke volume, PAWP, urinary output
-*if loss >30%, blood volume needs replacing
INTERPROFESSIONAL CARE
-*3:1 rule- 3ml of isotonic crystalloid for every 1ml of
EBL
Distributive shock: neurogenic shock -can occur within 30 minutes of a spinal cord injury at
the fifth thoracic vertebra or above. can last up to 6
weeks.
-can be induced by spinal anesthesia
-DEFINED: massive vasodilation, leading to pooling of
blood in vessels, tissue hypoperfusion, impaired
cellular metabolism
MANIFESTATIONS
-hypotension, bradycardia
-inability to regulate body temperature (heat loss)->
poikilothermia (taking on temp of environment)
-dry skin
INTERPROFESSIONAL CARE
-*stability for spinal cord injury
-*atropine for hypotension and bradycardia
-monitor for hypothermia
, Distributive shock: anaphylactic shock -acute life threatening allergic reaction
-massive vasodilation, release of vasoactive
mediators, increased capillary permeability
MANIFESTATIONS
-anxiety, confusion, dizzy
-sense of impending doom, chest pain
-incontinence
-swelling of lips and tongue, flushing, allergic rxn sx
-*resp distress and circulatory failure
INTERPROFESSIONAL CARE
-epi, diphenhydramine, famotidine
-*maintain patent airway (bronchodilators, aerosolized
epi, ET tube may be necessary
-*fluid replacement
