Emergency Flashcards
5Hs & 5 Ts causes in cardiac arrest
5 Hs:
- Hypothermia
- Hypoxia
- Hyper/Hypokalemia
- Hypovolemic
- Hydrogen ion excess (Acidosis)
5 Ts:
- Toxins
- Thrombus (cardio)
- thrombus (pulm)
- Tension pneumothorax
- Tamponade
ACLS cardiac arrest algorithm
Shockable rhythm (pVT,VF)
—>Shock –> CPR 2 mins–> check –> shock (with epi 1 mg q3-5 mins) + CPR 2 mins continue until ROSC
Not shockable rhythm (PEA, Asystole)
epi (1 mg) –> CPR 2 mins –> check if shockable proceed as above) –> epi q3-5 mins –> continue CPR 2 mins continue until ROSC
30:2 for breaths
ACLS tachycardia
> 150 bpm
SVT
Unstable –> synchronized cardioversion
wide QRS >0.12
- adenosine if reg
- antiarhythmic drugs
Narrow QRS
- vagal maneuvers
- adenosine (if regular)
ACLS bradycardia
<50 bpm
if stable monitor
if unstable:
- atropine
if failed transcutaneous pacing/epi infusions
