SET 1: Desired Oxygen (FiO₂) Equation
Equation:
New FiO₂ = Current FiO₂ × (Desired PaO₂ ÷ Current PaO₂)
A patient on 40% oxygen has a PaO₂ of 55 mm Hg. The desired PaO₂ is 80 mm Hg.
What FiO₂ should be set?
A patient receiving 50% oxygen has a PaO₂ of 62 mm Hg. The goal PaO₂ is 90 mm Hg.
Calculate the new FiO₂.

SET 2: CROP Equation
Equation:
CROP = (Cdyn × NIF × PaO₂/PAO₂) ÷ RR
Given:
Cdyn = 40 mL/cmH₂O
NIF = −30 cmH₂O
PaO₂ = 80 mm Hg
PAO₂ = 400 mm Hg
RR = 20 breaths/min
Calculate the CROP score.
Given:
Cdyn = 25
NIF = −20
PaO₂/PAO₂ = 0.25
RR = 30
Calculate the CROP score.
