CPR vetsci 4

CPA

• cardiopulmonary arrest

  • the sudden cessation of spontaneous and effective ventilation and circulation

5 signs of CPA

• no palpable pulse

• non auscultable heartbeat

• no ventilatory attempts

• discolored mm

• fixed dilated pupils

ROSC

return of spontaneous circulation

RECOVER goals/ purpose

• create evidence based guidelines and algorithms for CPR

• offer CPR certification at many levels (CE)

• continue to spearhead research into veterinary CPR

factors affecting survival rate (and which one has higher odds)

• pre arrest condition (chronic vs. acute)

  • acute higher ROSC

• time elapsed since arrest (witnessed vs. unwitnessed)

  • witnessed higher ROSC

• etiology of arrest (anesthetic vs. nonanesthetic)

  • anesthetic higher ROSC

phases of CPR

• basic life support (BLS)

• advanced life support (ALS)

BLS components

• chest compressions

• ventilation

• + drugs and IVC placement

ALS components

• medications

• defibrillation

• open chest compressions

during CPR what value counts as good perfusion?

• >15 mmHg

neurologic signs of impending CPA

• sudden changes in mentation

• loss of consciousness

  • comatose or obtunded

  • “star gazing” or spacing out

• opisthotones

• seizure activity

• strabismus or nystagmus

respiratory signs of impending CPA

• tachypnea or bradypnea

• sudden increase/decrease in resp effort

• slow rattling breaths

• agonal

circulatory signs of impending CPA

• pulse changes

  • weak, thready

  • development of deficits

  • abscence

• abnormal ECG patterns

  • increase in ventricular beats

  • sudden tachy/bradycardia

other signs of impending CPA

• mm - suddenly muddy/grey or pale

• ETCO2- under general anesthesia have asudden significant drop

rate of compressions

• 100-120 compressions/min

• contine for min 2 min

  • pause for 10 sec inbetween cycles

ventillation rate during CPR

• 10 resp/min

  • 1 breath every 6 sec
