A clean medical flowchart titled "TYPES OF SHOCK" based on surgery textbook content. The flowchart starts with a top box "SHOCK" branching into 4 main types arranged horizontally: 1. VASOVAGAL SHOCK (yellow) - arrow down to: "Sudden dilatation of peripheral & splanchnic vessels → Reduced cardiac output → Hypoxia (life-threatening)" 2. NEUROGENIC SHOCK (blue) - arrow down to: "Spinal cord injury → Dilatation of splanchnic vessels → Bradycardia, Hypotension, Arrhythmias" - then box: "Treatment: Vasoconstrictors, Dopamine, Phenylephrine (α agonist), O2, Airway, IV Fluids" 3. HYPOVOLAEMIC SHOCK (orange/red) - arrow down to causes box: "Haemorrhage (liver, spleen, bone fractures) | Vomiting/Diarrhoea | Burns" - then branches into 3 severity levels: MILD (<15%) "No significant change in HR/CO" → MODERATE (15-40%) "Cold periphery, tachycardia, confusion, metabolic acidosis" → SEVERE (>40%) "Hypotension, tachycardia, oliguria, SIRS → MODS" 4. CARDIOGENIC SHOCK (green) - arrow down to: "Circulatory failure → Tissue hypoxia | SBP <90 mmHg for 30 min | Cardiac index <2.2 L/min/m²" - then: "Cause: MI (50% LV wall damage within 24h) | Mortality >50%" - Diagnosis box: "ECG, Echo, ABG, Cardiac enzymes, PCWP" Bottom section: EFFECTS OF SHOCK on organs in a horizontal row of boxes: HEART (Low perfusion→tachycardia→DIC) | LUNG (ARDS) | METABOLIC (Lactic acidosis, ADH release) | KIDNEY (↓GFR, tubular necrosis) | BRAIN (Last organ underperfused) | GIT (Haematemesis, malaena) Use medical diagram style with color-coded boxes, clear arrows, white background, professional typography
