Key steps with a suspected cardiac arrest
Look for response in a collapsed patient
Shout for help whilst assessing for signs of life
Begin CPR immediately and ensure the resuscitation team are called by dialling 2222
Deliver high quality chest compressions with minimal pauses
sudden rise in CO2 indicates?
return of spontaneous circulation
once defib is connected when should the rhythm be checked?
at the earliest opportunity
Adrenaline in
1) VT/pVF
2) non shockable rhythm
1) Wait till after 3rd shock
2) when IV access is achieved
what % survive in hospital cardiac arrest?
20%
what % survive out of hospital cardiac arrest?
10%
Which rhythm is most common first monitored rhythm in a cardiac arrest
PEA / asystole
Which rhythm is most associated with hypovolaemia?
PEA / asystole
Aim C02 in ventilation
Ventilation should be adjusted to achieve normocarbia, PaCO2 4.7‒6.0 kPa.
Rate of chest compressions needed in adults
100-120 compressions per min
Fluid preferred in resuscitation?
CRYSTALLOIDS
Define hyperkalaemia
Define severe hyperkalaemia
Hyperkalaemia is defined as a plasma potassium concentration > 5.5 mmol L-1 severe hyperkalaemia is > 6.5 mmol L-1.
