HALYARD* MICROCUFF* Subglottic Suctioning Endotracheal Tube


Combining more effective subglottic suctioning with our advanced HALYARD* polyurethane cuff technology, you can finally provide the BEST protection against microaspirtion. HALYARD* MICROCUFF* Subglottic Suctioning Endotracheal Tubes are proven to be more effective at preventing and clearing clogs. Now you no longer have to struggle to make subglottic suctioning actually work!5,7,8

Finally, a Clear Change to Subglottic Suctioning

Using a subglottic suctioning endotracheal tube can cause clogged lumens. This makes it difficult and sometimes impossible to clear out using air bolus.


3 Simple Steps: Rinse. Suction. Clear.


MICROCUFF* Subglottic Suctioning ETT enables the safe use of saline rinsing to effectively clear clogs.7,9

  • Suction lumens clog up to 44% of the time -preventing effective suctioning of secretions.9
  • Saline rinsing is more effective than air bolus at loosening and clearing clogged suction lumens.9
  • The suction valve with integrated rinse port enables both suctioning and saline rinsing, without opening the suction circuit, preventing cross-contamination to both caregiver and patient.7



Suctions Secretions More Effectively and Efficiently…with a Push of a Button

  • When clogged lumens prevent effective suctioning, subglottic secretions are known to accumulate up to 13mL per hour, increasing the risk of microaspiration.2
  • With reports of suctioning dysfunction as high as 48% due to clogs,1,2 suctioning is inconsistent.



A Clear Change for Clearly Superior Results

  • A polyurethane cuff reduces channel formation, minimizing cuff leakage and enabling the use of saline6.
  • Polyurethane cuffs prevent fluid leakage, demonstrating 93% less mircroaspiration than TaperGuardtm Evac ETT.7
  • Because saline rinsing is more effective than air bolus at clearing clogs, subglottic secretions are suctioned more effectively9.
