Flashcards
Cardiogenic shock
Cards in this deck (7)
- 1Define cardiogenic shockDiminished cardiac output leading to impaired tissue perfusion
Most extreme form of pump failure - 2How much of the ventricle must infarct for cardiogenic shock to occur?40%
- 3What is the mortality of cardiogenic shock?>85% with treatment
- 4Signs and symptoms of cardiogenic shock- ALOC - Confusion, restlessness, anxiety, stupor, coma
- Poor perfusion - cool, clammy skin, pallor
- Weak or absent extremity pulses
- Tachycardia
- Slow or absent cap refil
- BP <90 systolic or >30mmHg below normal - 5Cardiogenic shock confounding factors- Arrhythmias
- Hypovolaemia
- Decreased vascualr tone - 6Treatment of cardiogenic shock- Priorities are:
- Rate
- Rhythm
- BP, volume, pump, vascular tone
- Improve oxygenation and peripheral perfusion
- Avoid increased cardiac workload/myocardial oxygen demand - 7Cardiogenic shock management, more detail- Keep pt supine unless dyspnoeic, do not elevate lower extremities
- Oxygenate via NRB
- Consider assisting ventilations, decrease work of breathing
- Monitor ECG
- IV TKVO, limit fluids unless RHF, IV morphine
- CCP to correct major rhythm disorders
