Airway situation
DKA / Severe Metabolic Acidosis Airway
The major danger is taking away the patient’s compensatory minute ventilation and then under-ventilating after paralysis.

Before intubation
- Estimate the patient’s pre-intubation respiratory compensation and anticipate very high minute ventilation demand.
- Resuscitate potassium, volume, shock, and reversible causes per local DKA/critical-care pathways before intubation if time allows.
- Plan post-intubation RR/VT strategy before medications are pushed.
During intubation
- Minimize apnea time and avoid delayed ventilation after paralysis.
- Use skilled first-pass technique and prepare for peri-intubation hypotension.
- Confirm with waveform EtCO2 but interpret EtCO2 in context of severe metabolic acidosis.
After intubation
- Immediately set minute ventilation intentionally and reassess pH/CO2 with blood gas.
- Continue DKA resuscitation and ICU pathway.
- Monitor for hypotension, electrolyte shifts, cerebral edema risk in peds, and ventilator-induced harm.
Common pitfalls
- Routine low minute ventilation after intubation.
- Long apnea while the patient is profoundly acidemic.
- Focusing on tube placement while DKA resuscitation stalls.
