⚠️ WARNING: Monitor closely for Auto-PEEP and breath stacking configurations. Exercise extreme caution in severe obstructive lung disease paths (e.g., Asthma/COPD exacerbations) where preserving adequate Expiratory Time (E-time) remains completely mission-critical.

3. PEEP/FiO2 Titration

FiO2 0.30.40.40.50.50.60.70.70.80.90.90.91.0
PEEP 5588101010121414161820-24
Lung Protection:
Tier 1 Vt (4–8 cc/kg • PBW)
Tier 2 Plateau Pressure ≤ 30 cmH2O
Tier 3 Driving Pressure (ΔP ≤ 15 cmH2O)
Physiological Drivers:
MINUTE VENTILATION (Ve) = RR x Vt
OXYGENATION (O2) = PEEP & FiO2
Fick’s Law | Gas Diffusion:
Surface Area x Diffusion Gradient
Membrane Thickness

PEEP ➔ Surface Area

FiO2 ➔ Diffusion Gradient

Membrane Disease:
  • Inflammation
  • Infection
  • Fibrosis
