Outline
Cardiogenic Shock
Definition/Etiology:
- Definition
- Circulatory failure
- Poor Perfusion = tissue/organ ischemia = Anoxia (Cell DEATH)
- Fluid Overload = Lung Injury → Edema
- Numerous Types = Cardiac Focus
- Analogy= Circulatory System = The Gas Station
- Gas Pump = Heart
- Hose = Vasculature
- Gasoline = Blood/Volume
- Vehicle = Tissues
- Circulatory failure
- Etiology/Cause
- CAD/MI*
- Acute Valve dysfunction
- Heart Failure
- Dysrhythmias
- Pericarditis = Cardiac Tamponade
Pathophysiology:
- Gas Pump Fails – Extreme version of Heart Failure
- Decreased Cardiac Output/Perfusion
- No Gas from Pump to vehicle
- Gas Runs backwards
- ↑CVP & Increased Fluid Overload
- Fluids must go somewhere
- Backs up to lungs = HF Sx
- Backs up to tissues and organs
- Fluids must go somewhere
- Compensatory
- ↑SVR
- Shunt blood to vital organs
- Kidney = no perfusion =oliguria
- Decreased Cardiac Output/Perfusion
Noticing: Assessment & Recognizing Cues:
- Subjective Cues (Typical Cardiac Patient)
- Chest Pain/SOB
- FEEL COLD
- Objective Cues (All point to poor perfusion)
- Vitals
- ↓BP (SBP<90) & Narrow Pulse Pressure
- ↑HR (Compensation)
- Hidden by Beta Blockers
- Pulses ↓
- Temp = Low
- Hemodynamics – Art Line
- Central Venous Pressure ↑
- Amount of blood backing up/not getting pumped through
- ↑ SVR (Compensation – Shunt Blood back to heart)
- +JVD/Edema
- Central Venous Pressure ↑
- Heart & Lung Sounds
- S3/Murmurs/Muffled Heart Sounds
- WET! Crackles/Rales
- ↓Tissue/Organ Perfusion
- Brain
- Kidneys
- Extremities
- Vitals
Interpreting: Analyzing & Planning:
- Labs
- H/H -hemorrhage
- Troponin -MI
- BNP – HF
- BMP/CMP – Electrolytes
- BUN/Creatinine – Arrhythmias
- Diagnostics
- ECG – Electricity
- Ischemia
- Alternans
- Echocardiogram – Plumbing
- Inflammation – Pericarditis
- Valves
- CXR – Heart Failure
- Cardiomegaly
- Pulmonary Edema/Effusion
- ECG – Electricity
Responding: Patient Interventions & Taking Action:
- ABCs & Treat Cause
- Lifesaving measures
- Pharmacological Interventions
- ↓SV (due to ↓ contractility and ↑ SVR)
- + Inotropes/Dobutamine or Milrinone
- ↑ Contractility
- Similar outcomes but Dobutamine is faster
- Vasopressors/Norepinephrine
- ↑ Vasoconstriction
- Generate pressure support
- Anticoagulants/Thrombolytics
- if MI/Clot
- Diuretics -Treats HF but may ↓ BP
- + Inotropes/Dobutamine or Milrinone
- ↓SV (due to ↓ contractility and ↑ SVR)
- Non-Pharmacological Interventions
- IABP – Heart Failure
- PCI: Angioplasty, Stent- (MI/Clot)
- Pericardiocentesis – (Tamponade)
- Cardioversion – Dysrhythmia)
- Open Heart (blown heart valve)
- Adjunct Medical Therapy
- Cardiology
- Interventionist/Surgeon
Reflecting: Evaluating Patient Outcomes:
- Airway/Breathing
- Sufficient oxygenation is provided
- Pulmonary congestion is decreased
- Hemodynamics/Circulation
- iSBP is increased to adequately perfuse tissues and vital organs.
- BP and pulse are within normal limits for the patient.
- Fluid and electrolyte balances are maintained
- Intake and output are balanced
Linchpins (Key Points):
- Notice
- Objective/Subjective Cues ↓ Perfusion
- Interpret
- Labs/Diagnostic -underlying cause
- Respond
- Treating underlying cause
- Hemodynamics
- Reflect
- ABCs are supported
