Single use self pressurising masked laryngeal airway

Experience the superior design with the new, SELF-PRESSURISING Masked Laryngeal Airway

The new air-Q®SP eliminates the extra step and guesswork for mask cuff inflation and the potential for over-inflation.

  • The new design allows Positive Pressure Ventilation to self-pressurise the mask cuff. The increase in cuff seal pressure occurs at the exact time you need it . . . during the upstroke of ventilation

On exhalation, the cuff decompresses to the level of the PEEP.

  • The intra-cuff pressure cycles between the Peak Airway Pressure usually between 15 – 30 cm H2O and the level of PEEP < 10 cm H2O. Seal pressure on exhalation averages 17 – 20 cm H2O.

Results . . . a safer, efficient, low-pressure seal during the majority of the case. The cyclical lowering in intra-cuff pressure may assist in diminishing complications such as:

  • Mucosal and nerve trauma that may result from over-inflating traditional peripheral laryngeal mask cuffs.

The new air-Q®SP can be used as an ‘everyday’ airway that facilitates intubation.


  • Significant reduction in post-operative sore throats1
  • Eliminates mask cuff over-inflation
  • A safer, efficient, low pressure seal during the majority of a case
  • Removable colour-coded connector facilitates intubation of upto an 8.5 ETT
