Cardiopulmonary Resuscitation Flashcards
what strength of adrenaline/epinephrine should be given in cardiac arrest and how often should it be given?
1) 1 in 10,000 (100mcg/ml) by intravenous injection.
2) dose : 1mg repeated every 3-5 minutes if necessary
Administration through a central line provides faster response than peripheral drug administration. what substance should be followed after a drug is given via peripheral administration?
A flush of at least 20ml sodium chloride 0.9% to aid entry into central circulation
Intravenous injection of amiodarone should be considered after adrenaline in cardiac arrest refractory to defibrillation. when in the advanced life support algorithm should this be administered?
After 3 shocks. An additional dose can be given if necessary followed by an intravenous infusion of amiodarone
↳ Lidocaine alternative
1) what is the compression-ventilation ratio in CPR?
2) How long should CPR continue for before pausing to reassess the patient?
3) How long should the total pause between chest compression to reassess the patient be?
1) compression-ventilation ratio of 30:2
2) 2 minutes
3) The total pause in chest compressions should be brief and no longer than 5 seconds
outline the post cardiac arrest treatment if patients who return to spontaneous circulation
1) Use ABCDE approach
2) Aim for SpO2 of 94-98%
3) Aim for normal PaCO2
4) 12 lead ECG
5) treat precipitating cause
6) Targeted temperature management
outline the MoA of adrenaline/epinephrine
Acts on both alpha and beta receptors and increases both heart rate and contractility (Beta 1 effects); it can cause peripheral vasodilation (Beta 2) or vasoconstriction (alpha effect)
when is adrenaline contraindicated?
no contraindications in cardiac arrest and anaphylaxis
in cardiac arrest restoration of cardiac output with the use of adrenaline is followed by which side effect?
Adrenaline-induces hypertension
