RESPIRATORY SCHOOL-EXAM MASTERY
YEAR 2 | PAGE 22G - PFTs, ABGs, HYPOXEMIA, IMAGING + PROBLEM-SOLVING
C. WHAT SCHOOL EXAMS COMMONLY REQUIRE
| Resource | Description | Link |
|---|---|---|
| Mechanics / volumes | Pressure gradients, compliance/recoil, airway resistance, surfactant, lung volumes/capacities and work of breathing. | |
| V/Q + hypoxemia | Apex/base physiology; V/Q mismatch, shunt, dead space, diffusion limitation, hypoventilation, A-a gradient and oxygen response. | |
| PFT / loops | FEV1, FVC, FEV1/FVC, TLC/RV/FRC, DLCO and flow-volume-loop patterns for obstructive, restrictive and upper-airway disease. | |
| ABG / acid-base | Primary respiratory vs metabolic disturbance, expected compensation, acute vs chronic respiratory disease and mixed disorders. | |
| Pulmonary disease | Asthma/COPD, ILD, pneumonia/TB, pleural disease, PE/pulmonary HTN, ARDS, respiratory failure and lung cancer patterns. | |
| Diagnostics / imaging | CXR/CT patterns, pulse ox/ABG, sputum/microbiology, D-dimer/CTPA concepts and when PFTs/imaging answer the question. | |
| Respiratory pharm | Bronchodilators, inhaled/systemic steroids, leukotriene drugs, antimicrobials, anticoagulants and signature adverse effects. |
E. RESPIRATORY ERROR-LOG TAXONOMY — MECHANICS/PFT - resistance/compliance/volume/loop logic. GAS-EXCHANGE - V/Q, shunt, dead space or A-a. ABG - primary disorder/compensation. DISEASE PATTERN - imaging/PFT/clinical clues. THERAPY - drug/oxygen/ventilation mechanism. SCHOOL-EXAM GATE
Proceed when you can identify the physiologic failure first, predict the PFT/ABG/imaging consequence before answer choices, and connect the disease mechanism to the correct diagnostic or therapeutic principle on unfamiliar cases. VIDEO-FIRST | SCHOOL-EXAM + BOARD-EXAM MASTERY
