Gas → Vent Copilot
Interpret the blood gas and reason the next ventilator move.
FiO₂ and MAP from the ventilator above are used for the Oxygenation Index.
Respiratory acidosis
Expected HCO3 rise: acute +1.5, chronic +5.3.
- • Elevated A-a gradient (90)
- • Increase minute ventilation: ↑ PIP by 1–2 cm H₂O (ΔP, the driver of Vt) and/or ↑ rate by 5–10 bpm.
- • Verify ETT position/patency, chest rise, and check for plug, kink, or pneumothorax before stacking changes.
- • Recheck gas in 20–30 min after a single deliberate change.
Educational nudge — confirm with bedside exam and use "Suggest next vent move" for full reasoning.
