🫁 Pneumothorax – NORCET Pearls
⭐ Air in the Pleural cavity
⭐ Sudden chest pain + Dyspnea = Suspect Pneumothorax
⭐ Trachea shifts away in Tension Pneumothorax
⭐ Hyperresonance on percussion
⭐ Breath sounds decreased/absent on affected side
⭐ Tension Pneumothorax = Medical Emergency
⭐ Immediate treatment: Needle decompression
⭐ Definitive treatment: Chest tube (Intercostal Drainage)

🩺 ABG (Arterial Blood Gas) – NORCET Pearls
⭐ Normal pH: 7.35–7.45
⭐ Normal PaCO₂: 35–45 mmHg
⭐ Normal HCO₃⁻: 22–26 mEq/L
⭐ Normal PaO₂: 80–100 mmHg
⭐ ROME Rule: Respiratory Opposite, Metabolic Equal
⭐ pH ↓ + PaCO₂ ↑ = Respiratory Acidosis
⭐ pH ↑ + HCO₃⁻ ↑ = Metabolic Alkalosis
⭐ pH ↓ + HCO₃⁻ ↓ = Metabolic Acidosis

🫀 ECG – NORCET Pearls
⭐ P wave = Atrial depolarization
⭐ QRS complex = Ventricular depolarization
⭐ T wave = Ventricular repolarization
⭐ Normal PR interval = 0.12–0.20 sec
⭐ Normal QRS duration = < 0.12 sec
⭐ ST elevation = Acute Myocardial Infarction (STEMI)
⭐ Tall peaked T wave = Hyperkalemia
⭐ Absent P waves + Irregularly irregular rhythm = Atrial Fibrillation
