BUILD THE NORMAL LUNG BEFORE THE DISEASE Use one connected model: PRESSURE/COMPLIANCE/RESISTANCE -> VENTILATION -> PERFUSION -> DIFFUSION -> O2/CO2 TRANSPORT -> SPIROMETRY. For every perturbation, predict the effect on airflow, V/Q, oxygenation, CO2, A-a gradient and work of breathing before naming the disease.

RESPIRATORY PHYSIOLOGY CLOSED-BOOK CHECK
A. DEEP RESPIRATORY CONCEPT VIDEOS - DIRECT & PLAYABLE
- Draw pressure changes through one breath; distinguish compliance, elastic recoil and airway resistance from first principles.
- Interpret lung volumes, FEV1, FVC, FEV1/FVC and flow-volume loops; predict obstructive vs restrictive shifts.
- Distinguish V/Q mismatch, shunt, dead space, diffusion limitation and hypoventilation using oxygen response and A-a logic.
- Connect ventilation and gas exchange to ABG direction, oxygen content and compensatory respiratory responses. VIDEO-FIRST | SCHOOL-EXAM + BOARD-EXAM MASTERY
