PREVIEW OF
EMT/EMR SHOCK & RESUSCITATIONPOWERPOINT TRAINING
PRESENTATION
ETHICAL ISSUES IN RESUSCITATION
Withholding resuscitation attemptsIrreversible deathDo Not Resuscitate (DNR) orders
Provide emotional support for family
IRREVERSIBLE DEATH
Signs includeDecapitationOther obvious mortal injuriesDecompositionPostmortem lividityPostmortem rigidity
Many areas require EKG confirmation
DO NOT RESUSCIATATE ORDERS
Advanced directive created by doctor and patientNormally is required to be shown at time of death Indicates patients wishes not to be resuscitated
EMOTIONAL SUPPORT FOR FAMILY
Ask if they need support from support fromPastor-either family or on callOther family membersSome employers provide “Employee
Assistance Programs” (EAP) and have a 24 hour phone assistanceEMT’s must maintain dignity & decorum
RESPIRATORY SYSTEM
Fresh oxygen to enter the lungs and blood supply
Respiratory waste products (CO2) to leave the blood and lungs
CARDIOVASCULAR SYSTEMVascular System
Arteries carry blood to tissuesVeins carry blood to heartHeart contraction can be felt as a pulse RadialCarotidBrachialFemoral
Veins (blue)
RESPIRATORY FAILURE
Definition- Reduction of breathing to the point where oxygen intake is not sufficient to support life
RESPIRATORY ARREST
DefinitionCondition that respirations have stopped
and can shortly lead to cardiac arrest if not immediately treated
GENERAL REASONS FOR THE HEART TO STOP BEATING
Sudden death and heart diseaseBreathing stops, especially in infants and childrenMedical emergenciesTrauma
CHEST COMPRESSIONS
Factors which decrease effectivenessCompression that are too shallowSlow compression rateSub-maximum recoilFrequent interruptions
SHOCK(POOR PERFUSION)
Results from inadequate delivery of oxygenated blood to body tissues
DEFINITION
Perfusion is the passage of blood and oxygen and other essential nutrients to the body’s cells
While delivering these essentials to the body’s cells, the circulatory system is also
removing waste such as carbon dioxide from the cells
DEFINITION
Shock is a state of hypoperfusion, or inadequate perfusion of blood through body tissues
Hypoperfusion can lead to death if not corrected
BLOOD VOLUME BY SIZE
Adult- 4-5 liters (females may be slightly higher)Child- 2.4 Liters (66 pounds)Infant- 0.8 Liter ( 22 pounds)
Volume is regulated by kidneys
ANATOMY & PHYSIOLOGY REVIEW
Heart & blood vesselsPhysiology of respiration
Gas exchangeAlveolar levelTissue level
CirculationPulmonarySystemic
HEART & BLOOD VESSELS
PULMONARY CIRCULATION
Is the portion of the cardiovascular system that carries blood between the heart and the lungs
DISRUPTIONS THAT CAN CAUSE SHOCK
Inadequate fluid/blood – blood/water lossFailing pump/heart
Disease or injury to conduction systemDamage to cardiac muscle
Leaky or dilated container/vesselsLoss of nervous controlSevere allergic reactionsMassive infectionHypothermia
COMPENSATED SHOCK
Earliest phaseUp to 5 to 15 % blood lossBody compensates by activating the
sympathetic nervous system
IRREVERSIBLE SHOCK
Rapid deterioration of the cardiovascular system
Greater blood shunting to heart & brainCell death begins which will progress over
several days
S & S OFIRREVERSIBLE SHOCK
Marked decrease in level of responsivenessDecreased respiratory rateProfound respiratory rateDecrease in pulse ratePatient feels impending doom
SHOCK DUE TO FLUID LOSS
Hypovolemic (hypovolemia)ExamplesSigns and symptoms
CARDIOGENIC SHOCK(PUMP FAILURE)
Caused by profound failure of the heartSevere MISevere heart failureTrauma to the heart
There is good peripheral vascular resistance & adequate blood volume, but the heart is not pumping properly
NEUROGENIC SHOCK
The nervous system is no longer able to control the diameter of the blood
vessels leading to hypovolemiaUsually from severe brain or CNS injury
SEPTIC SHOCK(SEPSIS)
Caused by an infection causing massive vasodilation
Blood plasma is lost through the vessel wallsResults in hypovolemia
PEDIATRICS
Common causes of shockTraumaFluid lossInfectionAnaphylaxisCongenital heart diseaseChest wall injury
GERIATRICS
AssessmentBody system changes affecting
presentations of shockVital sign changesAirwayBreathingCirculationSkin
MEDICATIONS MAY MASK SHOCK SYMPTOMS
Beta BlockersPrevent increase in heart rate
Decompsensation will be more will happen more quickly due to inability to raise heart rate & constrict blood vessels
