Out-of-hospital cardiac arrest (OHCA) Flashcards
What can the ambulance dispatcher usually tell someone ?
Where the nearest AED is
What does survival after OHCA depend on ?
Bystander CPR and AED.
ALS guidelines are essentially the same follow the ones outlined in prior decks
If you attend an OHCA and you are the solo attender which takes precedence; rhythm recognition +/- defibrillation or airway management ?
Rhythm recognition and attempted defibrillation (if appropriate).
In the presence of cardiorespiratory arrest and in the absence of a DNACPR ambulance crews should start CPR unless what?
The patient has a condition unequivocally associated with death:
* Decapitation
* Massive cranial or cerebral destruction
* Hemicorporectomy (or similar massive injury)
* Incineration >95% full thickness burns
* Decomposition/putrefecation
* Rigor mortis and hypostasis
How long should you continue OHCA resus attempts in:
Asystole/PEA
VF or pVT
If PEA/Asystole - attmpt for 20 mins and if all reversible causes have been identified and corrected, consider stopping
If in VF/pVT - take to cardiac arrrest centre with ongoing CPR as there may be a reversible cause e.g. PCI
What are the exceptions to considering stopping a resus attempt in OHCA when the rhythm remains PEA/Asystole after 20mins ?
- If young <18
- Drowned or hypothermic patient
- Poisoning or overdose
- Pregnant
Post ROSC care is similar pre-hospital as to in-hospital guidelines. There is only slight differences, should you initiate TTM?
No - its associated with a slight increased risk of APO and re-arrest so only done in-hospital
A structured approach to providing key informatio handover for pre-jospital to hospital care used the mnemonic ATMIST
