Critically ill patients are at notably increased risk of aspiration due to the following:

  • The challenge of appropriate, risk-minimizing positioning

  • Gastroparesis/dysmotility

  • Impaired cough/gag/swallow reflexes (illness- or drug-induced)

  • Impaired immune response

  • Intubation/extubation
