CPR Flashcards
CPR compression ratio:
30:2
O2 consumption in adults at rest:
250 ml/min
Chest compression should be delivered at a rate of at last:
100/min
Jake peocento normalniho CO dosahneme pri CPR:
25 - 30%
Jak nastavit ventilator pri CPR ?
DF 8 - 10 /min
Vt 6 - 7 ml/kg (500ml in average, one hand technique)
Defibrilace je synchronni/asynchronni?
asynchronni
CPR -4T:
Tension PNO / Tamponade / Trombembolism / Toxins
CPR - 4H:
Hypoxia / Hypovolemia / Hypotermia / Hypokalemia
CPP (Coronary Perfusion Pressure) is defined:
DAP - RAP
Adrenalin and CPR:
dose: 1mg
increase in CPP of 30% for 3min
Beta-mediated cardiac stimulation
Vasopressin and CPR:
dose: 40 U
causes coronary vasoconstriction
no Beta stimulation
Endotrachealni podani u CPR - leky:
Adrenalin
Vasopressin
Lidocaine
U endotrachealniho podani se davky zvyssuji:
2 - 2.5x
Davky amiodaronu u CPR:
- 300 mg (po 3.vyboji)
2. 150mg (po 4.vyboji)
Magnesium u CPR:
pouze u Torsade de pointes
1 - 2 g i.v. na 5min
Lidocaine u CPR:
1 mg/kg i.v. bolus
pak 0.5 mg/kg kazdych 5-10min
max.davka 3mg/kg
Jaka je hladina ETCO2 rozhodujici o preziti ve 20min resuscitace ?
10 - 15 mmHg
Jaka je hladina ScvO2 rozhodujici o uspechu resuscitace ?
30%
norma: 70 - 80%
Co znamena zkratka ROSC ?
Return Of Spontaneous Circulation
Jake % pacientu prezivsich resuscitaci neodejde z nemocnice ?
70%
Post-cardiac arrest syndrome is:
SIRS triggered by release of blood from areas of ischemia (reperf.inj.)
- Brain injury (failure to awaken, myoclonus, gen.seizures)
- Cardiac dysfunction (systolic and diastolic, stunning -> card.shock)
- SIRS (whole-body reperfusion injury)
What are shockable rythms?
VF (ventricular fibrilation)
VT (pulseless ventricular tachycardia)
Who is indicated for TTM (Target Temperature Management)?
any patient who doesn’t awake after following ROSC
Absolute contraindications for TTM (Target Temperature Management):
pre-existing hypotermia (<34st)
major bleeding
cryoglobulinemia
Relative contraindications for TTM (Target Temperature Management):
hemodynamic instability
cardiogenic shock
How is goal defined for TTM (Targeted Temperature Management):
body temperature: 32 - 34 st. (mild hypotermia)
meri se termistorem na katetru v moc.mechyri
TTM (Targeted Temperature Management) - Induction:
FR 500ml 4st. á 10min. (max.30 ml/kg)
goal: 34st. in bladder
Shivering -> deep sedation, muscle relaxants
Complications when TTM (Targeted Temperature Management) goes:
bradycardia (usually no intervention)
hypotension (cardiac depression, cold-induced diuresis)
hypokalemia (cave when rewarming -> hyperkalemia)
noncolvusive status epilepticus (10% of patients -> ECG)
Rewarmig from TTM (Targeted Temperature Management):
0.25 - 0.5 st/hod (slow rewarming)
CAVE: hyperkalemia
Post CPR predictive signs of poor outcome:
No pupillary reflex on day 3
No corneal reflex on day 3
Myoclonic status epilepticus on day 1 (repetitive irregular movements)
Is time to awaken post CPR a good predictor of neurologic outcome?
No
Is time to awaken post CPR a good predictor of neurologic outcome?
No
