Vent control

Low compliance / high alveolar-pressure branch

PIP and plateau both rise: think lung, pleural space, chest wall, tube position, or overdistension.

Lung problem pathwayARDS/shunt/pulmonary edema/pneumothorax.Overdistension / excessive VTPressure-volume loop and PBW branch.If BP fallsTension, PEEP, RV, or shock pathway.

Common causes

  • ARDS, pulmonary edema, or atelectatic lung.
  • Pneumothorax, pleural effusion, abdominal distension, chest-wall restriction.
  • Mainstem intubation or excessive VT/pressure.

Reassess

  • Tube depth, bilateral chest findings, ultrasound/radiography when appropriate, VT/PBW, Pplat, PEEP, and hemodynamics.
