UMEM Educational Pearls

Cuff Pressures and the Prevention of VAP

  • As highlighted in a recent pearl, ventilator-associated pneumonia (VAP) is the second most common nosocomial infection in the US and is associated with increases in ICU length of stay and mortality.
  • With increasing ED lengths of stay for many critically ill patients receiving mechanical ventilation, measures to prevent VAP should be initiated in the ED.
  • In addition to elevating the head of the bed to 30-45 degrees, another low cost intervention is the measurement of endotracheal tube cuff pressures.
  • Cuff pressures below 20 cm H2O increase the risk of VAP.
  • Measure cuff pressure within 4 hours of inflation and maintain between 20-30 cm H2O.
