when should you swap who is giving chest compressions?
every 2 mins
what are the 2 main things to remember?

what can be used to monitor response to resuscitation?
waveform capnography
what are the non-shockable rhythms?
Pulseless electrical activity
asystole
What are the shockable rhythms?
VT and VF
what is transthoracic imedance
the body’s resistance to electrical current flow
what can cause differing transthoracic impedances?
body mass age disease skin resistance tissue type and amount
when would you commence drugs in persistent VT/VF? and which drugs/doses?
after 3 shocks
adrenaline 1mg IV
amiodarone 300mg IV
when would you commence drugs during asystole/PEA? and which drugs/doses?
on spotting the rhythm,
adrenaline 1mg IV
then repeat every 3-5 mins
what would you do to treat hypoxia?
ensure patent airway
give high-flow O2- avoiding hyperinflation
