ARDS Workup
An ARDS algorithm console*
A five-step titration worksheet for respiratory care: screen for inclusion, tier severity, hold the plateau pressure ceiling, and work the gas back to a set rate. Each step unlocks the next.

Baseline & protocol inclusion
Evaluate 60 minutes after the initial ventilator setup. All three criteria must be present to enter the protocol.
Select a time zone above to unlock the workup. Every time written into the handoff note — the armed time, the timeline, and each scheduled task — is stamped in that zone. Times come from this device's clock and must be reviewed manually before they are entered into the patient record.
ARDS severity & PEEP titration
Tier on the P/F ratio measured with PEEP above 5 cmH₂O, then titrate PEEP to the tier target.
Verify the inclusion criteria to unlock severity tiering.
Plateau pressure & tidal volume
Hold an inspiratory pause on a passive breath, then compare plateau pressure against the 30 cmH₂O ceiling.
Tier severity to unlock the volume limits.
Arterial blood gas & rate optimisation
A pH inside the ARDSnet pH goal (7.30–7.45) needs no rate change. Otherwise aim for a PaCO₂ of 40 mmHg (Winter’s formula for a metabolic acidosis) and work back to a set rate.
Evaluate tidal volume to unlock the rate calculation.
Follow-up gas at 60 minutes
Screen the post-titration gas for refractory hypoxemia before settling into routine surveillance.
Complete the blood gas step to unlock the refractory screen.
