HALYARD* MICROCUFF* Adult Endotracheal Tube

Provides A Superior Tracheal Seal (3,4) … Proven to Reduce Leakage


Micro-aspiration of potentially infectious secretions through gaps in the endotracheal tube cuff is known to be a leading cause of VAP1. The cuff seal is the final barrier that protects the lungs from aspiration of potentially infectious pharyngeal secretions. When intubated, conventional high volume, low pressure (HVLP) PVC cuffs create channels that permit fluid to leak through the cuff and into the lungs.

MICROCUFF* features an advanced microthin polyurethane cuff, allowing channels to "self-seal" for increased protection against fluid leakage:

  • Polyurethane (10 microns) cuff membranes are substantially thinner than conventional PVC cuffs (50-80 microns)
  • Provides an effective seal at low cuff pressure
  • Designed for better contact with tracheal contour
  • Allows for greater visualization of vocal cords when cuff is deflated
  • Puncture strength is almost double compared to conventional2
  • Burst pressure is more than double compared to conventional2

The better the seal, the less micro-aspiration, the lower the risk of VAE and VAP.


"In conclusion, our in-vitro experiments show the recently introduced MICROCUFF* tube cuff to be the only one of the tested HVLP endotracheal tube cuffs that effectively prevents fluid leakage around the tracheal tube when cuff pressure was set to 30 cm H2O or less."
