When should the primary assessment occur before the BLS assessment?
If the pt is conscious
How should you maintain an open airway in an unconscious patient?
What are the types of advanced airway management?
What should you confirm when using advanced airway management?
What is the best way to confirm/monitor airway placement?
Continuous waveform capnography
Note: Physical exam should be complimentary.
What % supplemental oxygen should be used in pts with cardiac arrest?
100%
What % supplemental oxygen should be used in pts undergoing a primary assessment and not in cardiac arrest?
Adjust oxygen level to achieve O2 saturation of 95% to 98%
Note: In acute coronary syndrome you should target an O2 saturation of 90%.
How should you monitor adequacy of ventilation?
Note: Avoid excessive ventilation.
What value indicates adequate CPR quality when using quantitative waveform capnography?
10 mm Hg CO2 (at end expiration)
Note: If less than 10 mm Hg, attempt to improve CPR quality (rare to get ROSC in this situation).
While performing CPR, the end expiration CO2 rapidly increases to more than 25 mm Hg…
This may indicate ROSC (check for consciousness/pulse at next pulse check)
What should the intra-arterial diastolic pressure be during adequate quality CPR?
20 mm Hg or more
Note: If less than 20 mm Hg, attempt to improve CPR quality.
What are the components of the primary assessment?
What are the primary assessment levels of consciousness?
AVPU:
1st degree heart block
Note: PR interval is greater than 0.2 seconds (1 big box).
2nd degree AV block (type 1), AKA Wenkebach
2nd degree AV block (type 2)
2:1 block (a subtype of 2nd degree type 2 AV block where every other QRS complex is dropped)
3rd degree AV block
Treatment for stable bradycardia
First line treatment for unstable bradycardia
Atropine (1 mg bolus, repeated as needed every 3-5 min to a max of 3 mg)
Second line treatment for unstable bradycardia
Note: Consider expert consultation and/or transvenous pacing.
When should bradycardia be considered unstable?
What is the adult dopamine dose for unstable bradycardia?
5-20 mcg/kg dopamine per minute (titrated to pt response)
What is the adult epinephrine dose for unstable bradycardia?
2-10 mcg epinephrine per minute (titrated to pt response)
